Nerve Root Injuries• “stingers” or “burners”• Most common cervical injury in football
• ~8% incidence in college football• Initially complains of total arm weakness, and dysethetic
pain which usually resolves from minutes to 24 hours• Numbness and muscle group weakness may persist.

Nerve Root Injuries• Treatment
• Can return to play when symptoms have resolved and player has full, non-painful ROM
• If player has pain with or limited ROM cervical x-rays should be done to r/o fracture/dislocation
• If neurological symptoms continue for 3-4 weeks EMG/NCV can be done to evaluate function

Cervical Fracture/Dislocation• Fractures and dislocations again are a spectrum of
injuries • Subluxation w/o fracture or neurologic injury• Fracture-Dislocations with cord injury
• Acutely there is painful ROM and guarding• Immobilize and image.
![Page 27: Spine Trauma in Sports - Bone & Joint Center · • AP, Lat, Flexion and Extension, +/- open odontiod ... • Degenerative disease and annular tears • Axial pain that persists past](https://reader034.fdocuments.net/reader034/viewer/2022052000/6011c4f1d60b394aa83044d9/html5/thumbnails/27.jpg)
Cervical Fracture/Dislocation• Over the last 50 years there has been a significant
decrease in morbidity associated with spine fractures due to adherence of spine precautions prior to arriving at the hospital
• Leave all equipment in place• Log roll onto and transfer on back-board
![Page 28: Spine Trauma in Sports - Bone & Joint Center · • AP, Lat, Flexion and Extension, +/- open odontiod ... • Degenerative disease and annular tears • Axial pain that persists past](https://reader034.fdocuments.net/reader034/viewer/2022052000/6011c4f1d60b394aa83044d9/html5/thumbnails/28.jpg)
Cervical Fracture/Dislocation• Treatment is based on concept of stability
• Stable – non-operative (immobilization)• Unstable – operative treatment/immobilization
• What constitutes spinal stability is sometimes hard to determine• White et al described stability as “the spines ability to limit it’s
patterns of displacement during physiologic loads to prevent damage or irritation to the spinal cord and nerve roots”
![Page 29: Spine Trauma in Sports - Bone & Joint Center · • AP, Lat, Flexion and Extension, +/- open odontiod ... • Degenerative disease and annular tears • Axial pain that persists past](https://reader034.fdocuments.net/reader034/viewer/2022052000/6011c4f1d60b394aa83044d9/html5/thumbnails/29.jpg)
Cervical Fracture/Dislocation• Even among spine surgeons there is controversy• In general instability is present if
• Cord injury• Greater than 3.5mm of displacement in adult spine with
flexion and extension films• Greater than 20 deg in angulation with flexion extension
films (or 11 deg in static lateral)

Spine Injuries• Serious injury to the spine during sports is uncommon• With improvement in equipment, coaching, and pre-
hospital care the incidence has decreased.
