Introduction
bull Surgery is trending toward minimally invasive surgery worldwide including spine surgery
bull Advancements in instrumentation fiber optics laser technology fluoroscopic imaging high resolution video imaging endoscopy along with the accumulated experience in endoscopic laser spine surgery made MISS possible
bull MISS requires more precise delicate and effective method for spinal decompression
bull MISS does not de-stabilize the vertebral segments
bull Can safely treat multiple level symptomatic spinal discs spinal stenosis and high risk spinal patients
What is Minimally Invasive Spine Surgery (MISS)
spinecentercom
Introduction
bull Endoscopic MISS is a technologically dependent surgery requiring utilization of advanced endoscopic surgical instruments imaging-video technology and tissue modulation technology in a digital operating room (DOR)
bull It requires seamless connectivity and control to perform the surgical procedures in a precisely orchestrated manner
bull Therefore a new integrated technological convergence and control system (SECS) SurgMatixreg (US Patent) was created by myself
and Professor HK Huang USC MC to facilitate MISS
bull This system facilitates MISS with ldquoorganized control instead of organized chaosrdquo in an endoscopic DOR suite and enables a safer precise and more effective surgery

Introduction
bull If conservative treatment fails and continue to have persistent significant symptoms affecting their daily activities and ability to work this can lead to the need for surgical decompression of the disc
bull In the past the only method was open traumatic lumbar surgery with cutting of the muscle bone and the disc and even spinal fusion which are associated with long periods of recovery wound healing blood loss hospitalization and others

ndash Larger surgical incision ndash longer healing time
ndash More traumatic than MISS and more blood loss
ndash Often is performed under general anesthesia
ndash Higher risk and complication rate
ndash Long and painful recovery time
ndash Higher long term complication rate including post fusion junctional disc herniation syndrome (JDHS 19-49 after 4-5 years)
ndash Alarming high rate of ldquofailed back syndromerdquo

Advantages of MISS
bull An out patient or same day surgeryldquo no hospitalization
bull Less traumatic
bull Small or tiny incision
bull Costs less - approximately 40 less than a open spinal surgeryfusion
bull Economic savings for the employee and employer are significant due to earlier return to work
bull Done under local anesthesia except occasional brief general anesthesia
bull Early post ndash op exercise one day after surgery
bull Surgical triad approach and critical fan-sweep maneuver further facilitate the disc decompression and improves surgical result
bull Multiple level spinal discectomy can be performed at one sitting with minimal risk
bull Can be done for high risk anesthesia patients with morbid obesity emphysema and cardiac conditions under local anesthesiaIV sedation at much less risk
bull Intra-operative neurophysiologicalEMG monitoring and direct visualized endoscopic significantly reduces the chance of inadvertent injury of neural structure
bull Preserves spinal motion

Introduction
bull If conservative treatment fails and continue to have persistent significant symptoms affecting their daily activities and ability to work this can lead to the need for surgical decompression of the disc
bull In the past the only method was open traumatic lumbar surgery with cutting of the muscle bone and the disc and even spinal fusion which are associated with long periods of recovery wound healing blood loss hospitalization and others

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS

monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance
bull Infection
ndash Avoided by sterile technique and intraoperative I-V prophylactic antibiotics
ndash Aseptic discitis can be prevented by aiming the laser beam in a ldquobowtierdquo fashion to avoid damaging the endplates
bull Hematoma (subcutaneous and deep)
ndash May occur but is minimized by careful technique
ndash Not prescribing aspirin or NSAIDrsquos prior to surgery
ndash Applying digital pressure or an I-V bag over the operative site after surgery
All potential complications of open approaches are possible for endoscopic MISS but rare or much less frequent
spinecentercom
Potential Complications and their Avoidance
bull Operating wrong level

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological
monitoring optimizes the anesthesia for MISS

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological
monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance
bull Dorsal Root Ganglion Injury
ndash A common complication for posterior lateral lumbar approach with dysesthesia (mostly transient permanent less than 1)
ndash Careful endoscopic technique and knowledge of foraminal anatomy
ndash C-arm fluoroscopic monitoring
ndash Using cannulae and endoscope that fit the foramen
ndash Careful using laser in the foraminal area Lumbar laser foraminoplasty with
steerable spinoscope with proximity to dorsal lumbar root ganglion
spinecentercom
Potential Complications and their Avoidance
bull Excessive sedation
ndash Continuous conscious EEG monitoring with the new computerized SNAPtrade monitoring (SNAP index) improves anesthesia and reduces drug requirement
ndash Local anesthesia with conscious sedation provides a responsive patient to facilitate endoscopic MISS and prevents potential complications

spinecentercom
Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS
spinecentercom
Potential Complications and their Avoidance
bull Pneumothorax potential complication for all approaches to thoracic discs
ndash Introduction of the micro instruments through the ldquosafety zonerdquo as described previously prevents complication
ndash Chest x-ray is obtained immediately after completing the operation to rule out pneumothorax
Posteriorlateral Endoscopic Thoracic Discectomy Endoscopic Instruments and Intercostal Nerve
spinecentercom
Potential Complications and their Avoidance
bull Bowel and ureteral injuries extremely
rare
ndash Ureteral injuries not reported with MISS
ndash Bowel perforation in the early experience with percutaneous lumbar discectomy
ndash None in recent multiple center study of 32100 cases
ndash Knowledge of the surgical anatomy avoids potential complications

spinecentercom
Goals of SurgMatixreg SECS integration system
to facilitate and control MISS
bull Provides a complete picture of the patientrsquos medical history and status by consolidating data from multiple IT and OR systems ndash patient transparent
bull Improves patient safety by converging pre-op intra-op and post-op data and OR control ndash patient centric
bull Offers a complete ldquoreal-timerdquo picture of the patientrsquos medical status including vital signs wave form and biosensor data
bull Promotes workflow efficiency in the DOR reducing personnel and other costs leading to a significant economic saving in an ldquoorganized control instead of an organized chaosrdquo environment
bull Enhances quality of patient care by providing information available to all OR staff and facilitating communication in the DOR
bull Facilitates post-surgical care and trend analysis through increased data collection during surgery

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological
monitoring optimizes the anesthesia for MISS

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological
monitoring optimizes the anesthesia for MISS

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological
monitoring optimizes the anesthesia for MISS

Discussion
Potential Complications and their Avoidance
Pearls Tips and Tricks
spinecentercom
Potential Complications and their Avoidance
bull Infection
ndash Avoided by sterile technique and intraoperative I-V prophylactic antibiotics
ndash Aseptic discitis can be prevented by aiming the laser beam in a ldquobowtierdquo fashion to avoid damaging the endplates
bull Hematoma (subcutaneous and deep)
ndash May occur but is minimized by careful technique
ndash Not prescribing aspirin or NSAIDrsquos prior to surgery
ndash Applying digital pressure or an I-V bag over the operative site after surgery
All potential complications of open approaches are possible for endoscopic MISS but rare or much less frequent
spinecentercom
Potential Complications and their Avoidance
bull Operating wrong level
ndash A major complication of all spine surgery
ndash Avoided by using digital C-arm fluoroscopy for accurate anatomic localization
ndash Provocative discogram verifies level
bull Dural Tear
ndash Gross dural tear very rare
ndash Dural injury evidenced by spinal headache and presumed csf leak (less than 1)
ndash No surgery required to repair a CSF leak
ndash Spinal headache responds to epidural blood patch

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological
monitoring optimizes the anesthesia for MISS

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological
monitoring optimizes the anesthesia for MISS

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological
monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance
bull Infection
ndash Avoided by sterile technique and intraoperative I-V prophylactic antibiotics
ndash Aseptic discitis can be prevented by aiming the laser beam in a ldquobowtierdquo fashion to avoid damaging the endplates
bull Hematoma (subcutaneous and deep)
ndash May occur but is minimized by careful technique
ndash Not prescribing aspirin or NSAIDrsquos prior to surgery
ndash Applying digital pressure or an I-V bag over the operative site after surgery
All potential complications of open approaches are possible for endoscopic MISS but rare or much less frequent
spinecentercom
Potential Complications and their Avoidance
bull Operating wrong level
ndash A major complication of all spine surgery
ndash Avoided by using digital C-arm fluoroscopy for accurate anatomic localization
ndash Provocative discogram verifies level
bull Dural Tear
ndash Gross dural tear very rare
ndash Dural injury evidenced by spinal headache and presumed csf leak (less than 1)
ndash No surgery required to repair a CSF leak
ndash Spinal headache responds to epidural blood patch

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological
monitoring optimizes the anesthesia for MISS

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological
monitoring optimizes the anesthesia for MISS

bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS

Intraoperative Neurophysiological Monitoring - IOM
bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited
visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct
visualization with fluoroscopy and endoscopy
creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP
and MEP can provide the surgeon with useful
feedback to avoid neural trauma during MISS

bull Trend of spinal surgery is toward less or
minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less
morbidity and improved surgical outcome

visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL
MONITORING (IOM) of neural structure direct

visualization and exposure of the relevant
anatomy in spite of fluoroscopy and endoscopy to
work with and potentially placing the relevant
neural structures at increased risk of trauma

spinecentercom
Potential Complications and their Avoidance
bull Infection
ndash Avoided by sterile technique and intraoperative I-V prophylactic antibiotics
ndash Aseptic discitis can be prevented by aiming the laser beam in a ldquobowtierdquo fashion to avoid damaging the endplates
bull Hematoma (subcutaneous and deep)
ndash May occur but is minimized by careful technique
ndash Not prescribing aspirin or NSAIDrsquos prior to surgery
ndash Applying digital pressure or an I-V bag over the operative site after surgery
All potential complications of open approaches are possible for endoscopic MISS but rare or much less frequent
spinecentercom
Potential Complications and their Avoidance
bull Operating wrong level
ndash A major complication of all spine surgery
ndash Avoided by using digital C-arm fluoroscopy for accurate anatomic localization
ndash Provocative discogram verifies level
bull Dural Tear
ndash Gross dural tear very rare
ndash Dural injury evidenced by spinal headache and presumed csf leak (less than 1)
ndash No surgery required to repair a CSF leak

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS
spinecentercom
Potential Complications and their Avoidance
bull Pneumothorax potential complication for all approaches to thoracic discs
ndash Introduction of the micro instruments through the ldquosafety zonerdquo as described previously prevents complication
ndash Chest x-ray is obtained immediately after completing the operation to rule out pneumothorax

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS
spinecentercom
Potential Complications and their Avoidance
bull Pneumothorax potential complication for all approaches to thoracic discs

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS
spinecentercom
Potential Complications and their Avoidance

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS
spinecentercom
Potential Complications and their Avoidance
bull Pneumothorax potential complication for all approaches to thoracic discs

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS
spinecentercom
Potential Complications and their Avoidance
bull Pneumothorax potential complication for all approaches to thoracic discs
ndash Introduction of the micro instruments through the ldquosafety zonerdquo as described previously prevents complication

Potential Complications and their Avoidance With IOM
bull Trend of spinal surgery is toward less or minimally invasive spine surgery (MISS)
bull MISS aims at being less traumatic with less morbidity and improved surgical outcome
bull The obvious challenge of MISS is limited visualization and exposure of the relevant anatomy in spite of fluoroscopy and endoscopy to work with and potentially placing the relevant neural structures at increased risk of trauma
bull INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IOM) of neural structure direct visualization with fluoroscopy and endoscopy creates safer endoscopic MISS procedures
bull Spontaneous EMG monitoring at times SSEP and MEP can provide the surgeon with useful feedback to avoid neural trauma during MISS
bull Intra-operative surface EEGneurophysiological monitoring optimizes the anesthesia for MISS
spinecentercom
Potential Complications and their Avoidance
bull Pneumothorax potential complication for all approaches to thoracic discs
ndash Introduction of the micro instruments through the ldquosafety zonerdquo as described previously prevents complication
ndash Chest x-ray is obtained immediately after completing the operation to rule out pneumothorax
Posteriorlateral Endoscopic Thoracic Discectomy Endoscopic Instruments and Intercostal Nerve

Potential Complications and their Avoidance
bull Bowel and ureteral injuries extremely
rare
ndash Ureteral injuries not reported with MISS
ndash Bowel perforation in the early experience with percutaneous lumbar discectomy
ndash None in recent multiple center study of 32100 cases
ndash Knowledge of the surgical anatomy avoids potential complications

Surgical ePR Control System (SECS)
bull To facilitate and to avoid potential risks and complications in MISS
bull The Surgical ePR Control System (SECS) (SurgMatixreg) being patient
transparent provides a complete clinical picture with live ldquoreal timerdquo data of a patient in a DOR it consolidates key clinical and surgical data which can be instantly accessed and viewed
bull This patient centric system enhances and improves the quality and safety of patient care and provides significant data for clinical analysis education training further development of MISS

Goals of SurgMatixreg SECS integration system
to facilitate and control MISS
bull Provides a complete picture of the patientrsquos medical history and status by consolidating data from multiple IT and OR systems ndash patient transparent
bull Improves patient safety by converging pre-op intra-op and post-op data and OR control ndash patient centric
bull Offers a complete ldquoreal-timerdquo picture of the patientrsquos medical status including vital signs wave form and biosensor data
bull Promotes workflow efficiency in the DOR reducing personnel and other costs leading to a significant economic saving in an ldquoorganized control instead of an organized chaosrdquo environment
bull Enhances quality of patient care by providing information available to all OR staff and facilitating communication in the DOR
bull Facilitates post-surgical care and trend analysis through increased data collection during surgery

EducationTraining for Endoscopic MISS
ndash Thorough knowledge of the surgical anatomy and the surgical procedure
ndash Specific endoscopic MISS training
ndash Hands-on experience in a laboratory including cadaveric
ndash Meticulous pre-operative surgical planning
ndash Working closely with an experienced endoscopic spine surgeon through the steep surgical learning curve
ndash Fluoroscopy as ldquoThe 3rd Eyerdquo or ldquoEye of Wisdomrdquo for confirmation of location of instruments endoscopy alone is not enough
ndash Use of digital imaging system PACS enhanced 3D visualization and use of SurgMatixreg -in DOR
bull Endoscopic MISS has numerous obvious advantages but requires
bull Training is critical in order to perform endoscopic MISS effectively safely and avoid potential complications
Computer assisted endoscopic MISS trainer
