Terminal Learning ObjectiveTerminal Learning Objective
Given a casualty who has a suspected musculoskeletal injury,
manage a musculoskeletal injury
IAW Prehospital Trauma Life Support Chapters 12 and 21.

AssessmentAssessment
Consider the MOI and visualize possible primary injuries (most obvious) and secondary injuries (less obvious, but located in the path of
the injury).
Assess and manage any life threatening hemorrhage and injuries that affect the
casualty's airway, breathing and circulation.

AssessmentAssessment
In which three categories can musculoskeletal injuries be placed?
Isolated non life-threatening musculoskeletal trauma Non life-threatening musculoskeletal trauma, but with
multisystem life-threatening trauma Definite musculoskeletal life-threatening injuries.
Bleeding from pelvic fractures can be fatal.

AssessmentAssessment
How does placing musculoskeletal injuries in categories help?
These categories will help you understand the priority of care.
Loss of 1-2 liters of blood can be caused by the fracture of one
femur.

AssessmentAssessment
What signs and symptoms do you expect from musculoskeletal injuries?
Swelling, deformities, crepitus, limited range of motion, and pain.
Once a sign or symptom is found, no additional or repetitive steps should be taken to
reproduce it.That’s just mean….

AssessmentAssessment
When is PMS assessed?Distal to all extremity injuries.
Before and after splinting any extremity.
What do abnormal findings tell you about the extent of the injury?
Loss of motor and sensory function usually indicates nerve injury.
Loss of motor, sensory and pulse indicate a serious arterial and
nerve injury.

Multisystem TraumaMultisystem Trauma
Life takes precedence over limb.
Focus on maintaining vital function. Hemorrhage, Airway, Breathing, Circulation
Limited measures should be taken to addressing musculoskeletal injuries of the
extremities.
![Page 9: Point of Wounding: Musculoskeletal trauma](https://reader034.fdocuments.net/reader034/viewer/2022050816/54c226fe4a79591a7d8b45ca/html5/thumbnails/9.jpg)
Amputation and AvulsionsAmputation and Avulsions
How is life threatening hemorrhage of the
extremities controlled?Tourniquet
Amputations may not immediately bleed due to vascular spasms of the
injured vessels. Once the spasms subside,
bleeding will occur.

Compartment SyndromeCompartment Syndrome
What are the five P’s of compartment syndrome?
PainParesthesias (par·es·the·sia)
(burning, prickling, pins and needles, itching, or tingling of the skin)
Pulselessness
Paralysis
Pallor
![Page 12: Point of Wounding: Musculoskeletal trauma](https://reader034.fdocuments.net/reader034/viewer/2022050816/54c226fe4a79591a7d8b45ca/html5/thumbnails/12.jpg)
Compartment SyndromeCompartment Syndrome
What is the corrective action if compartment syndrome is suspected?
Loosen tightly applied splints or dressings.
Tighten tourniquets or apply a second tourniquet directly above the first until a distal pulse can no
longer be detected.

Crush SyndromeCrush Syndrome
Damaged muscle tissue releases myoglobin and potassium.
Myoglobin can cause damage to the kidneys. This free myoglobin will produce tea or cola colored urine.
Elevated potassium can cause cardiac arrhythmias.
When the casualty is extricated and the injury is reperfused,
new blood washes the old blood with the accumulated toxins into the system.
![Page 14: Point of Wounding: Musculoskeletal trauma](https://reader034.fdocuments.net/reader034/viewer/2022050816/54c226fe4a79591a7d8b45ca/html5/thumbnails/14.jpg)
Crush SyndromeCrush Syndrome
When possible, achieve vascular access and contact a MO
before extrication.
Provide aggressive fluid resuscitation with
Normal Saline.(Lactate Ringers contains potassium)

Mangled ExtremitiesMangled Extremities
Involves skin, muscle, tendons, bone, vessels, nerves. The focus is life-threatening conditions. Apply tourniquets to control hemorrhage.
Evacuate the casualty as an urgent surgical priority.

What is crush syndrome?
Damaged muscle tissue releases myoglobin and potassium.
Myoglobin is a storage site within muscle tissue that stores oxygen. When released from damaged
muscle, it can cause damage to the kidneys. The free myoglobin will produce tea or cola colored urine.
Elevated potassium levels can cause cardiac arrhythmias.

What is the most common cause of compartment syndrome in combat casualties?
Instances found in combat casualties are commonly caused when arterial blood flow continues into an
extremity, but venous flow is restricted from returning to the system.
What are the five “P”s of compartment
syndrome?
Pain, Paresthesias, Pulselessness, Pallor and Paralysis
![Page 18: Point of Wounding: Musculoskeletal trauma](https://reader034.fdocuments.net/reader034/viewer/2022050816/54c226fe4a79591a7d8b45ca/html5/thumbnails/18.jpg)

Manage Musculoskeletal InjuriesManage Musculoskeletal Injuries
Assess and manage any life threatening hemorrhage and injuries that affect the
casualty's airway, breathing and circulation.
If the tactical situation and the casualty's condition allows, splint suspected
musculoskeletal injuries.
In a hostile environment, there may not be time to splint an injury.
![Page 20: Point of Wounding: Musculoskeletal trauma](https://reader034.fdocuments.net/reader034/viewer/2022050816/54c226fe4a79591a7d8b45ca/html5/thumbnails/20.jpg)
Manage Musculoskeletal InjuriesManage Musculoskeletal Injuries
Why do we splint musculoskeletal injuries?
Prevent motion in the broken bone ends.Not only decreases pain but also eliminates further damage to muscles, nerves, and blood vessels and
helps to control hemorrhage.
![Page 21: Point of Wounding: Musculoskeletal trauma](https://reader034.fdocuments.net/reader034/viewer/2022050816/54c226fe4a79591a7d8b45ca/html5/thumbnails/21.jpg)
Splinting ConsiderationsSplinting Considerations
Expose if the tactical situation allows.
Check PMS before and after splinting.If distal pulses are absent, apply gentle traction
in an attempt to realign it.
Splints must be long enough to immobilize the joint above and the joint below the injury and
rigid in order to keep the bone from moving.
![Page 22: Point of Wounding: Musculoskeletal trauma](https://reader034.fdocuments.net/reader034/viewer/2022050816/54c226fe4a79591a7d8b45ca/html5/thumbnails/22.jpg)
Splinting ConsiderationsSplinting Considerations
If possible, use at least four ties (two above and two below the fracture) with nonslip knots to secure the
splints.
If splinting material is not available, then swathes or a combination of swathes and slings can be used to immobilize an extremity with an anatomic splint.

Splinting MaterialSplinting Material
When using improvised material, what are some general rules to follow and why?
If raw materials are not available, anatomical splints may be utilized.
Splints should be padded.
Narrow materials should not be used to secure a splint.

Pain ManagementPain Management
Splinting the injury will greatly reduce the pain.
Pharmaceutical pain management includes Morphine or Fentanyl
When are analgesics recommended?Isolated joint and limb injuries.
When are analgesics NOT recommended?Casualties with serious multisystem trauma.

AntibioticsAntibiotics
If the casualty is conscious and able to swallow, direct them to take their combat
pill pack.
If necessary and available, provide IV antibiotics

How should musculoskeletal trauma be treated in the following circumstances:
If the tactical situation and the casualty's condition allows?
Splint suspected musculoskeletal injuries.
In a life-threatening situation?Injuries may be splinted while the casualty is being
transported.
In a hostile environment? There may not be time to splint an injury.

When treating a musculoskeletal injury of an extremity, you find the distal pulse is absent.
What is the next step?Apply gentle traction in an attempt to realign it. If resistance is encountered, splint the extremity in the
position found.
When should pain management be considered for musculoskeletal injuries?
Analgesics are recommended for isolated joint and limb injuries, but not for casualties with serious
multisystem trauma.
