How Car Accidents Cause Shoulder Injuries
Shoulder injuries in car accidents result from several mechanisms: seatbelt restraint forces that compress the shoulder against the chest wall; airbag deployment impact against the outstretched arm; bracing against the steering wheel or door at the moment of impact; and occupant restraint causing traction forces on the shoulder joint. Each of these mechanisms preferentially injures different shoulder structures.
Common Shoulder Injuries
- rotator cuff tear: Tear of one or more of the four rotator cuff tendons, causing pain, weakness, and limited overhead motion
- SLAP tear: Tear of the superior labrum, causing deep shoulder pain, clicking, and instability
- Acromioclavicular (AC) joint injury: Separation of the AC joint from direct impact or seatbelt forces
- Shoulder impingement: Compression of rotator cuff tendons in the subacromial space following traumatic inflammation
- Biceps tendon injury: Partial or complete tear of the long head of the biceps tendon
MRI and Treatment at MAIC
Shoulder MRI — with arthrogram when labral pathology is suspected — provides definitive diagnosis of all shoulder injuries. MAIC's orthopedic surgeons provide causation opinions and surgical consultation for shoulder injuries. Call (888) 991-5290.
