Thoracic outlet syndrome (TOS) is a condition in which nerves, arteries, or veins in the space between the collarbone and the first rib become compressed. While TOS can result from repetitive overhead work or anatomical variation, motor vehicle accidents are a significant cause — particularly rear-end collisions that strain the neck and shoulder muscles.
Why Car Crashes Cause TOS
During a whiplash-type injury, the muscles of the neck and upper shoulder — particularly the anterior and middle scalenes, and the pectoralis minor — sustain rapid stretch injuries. These muscles, when in prolonged spasm or when they develop scar tissue, can narrow the thoracic outlet and compress its neurovascular contents. The result is a cluster of symptoms that may not appear until days or weeks after the accident.
Symptoms of TOS After a Crash
- Pain, numbness, or tingling in the arm, hand, or fingers
- Weakness in the grip or shoulder
- Heaviness or fatigue in the arm, especially with overhead activity
- Coolness or color change in the hand (vascular TOS)
- Neck and shoulder pain that worsens with arm elevation
Chiropractic Treatment for TOS
Chiropractic care addresses TOS by treating both the spinal component (cervical misalignment that may crowd nerve roots) and the soft-tissue component (scalene and pectoral tightness that narrows the outlet). Treatment includes cervical and thoracic adjustments, rib mobilization, and targeted soft-tissue therapy for the affected muscles.
If you've noticed arm or hand symptoms following a car accident, don't dismiss them as coincidence. TOS is a recognized and treatable post-accident condition. Contact Total Health Family Clinic in Hyattsville or District Heights for an evaluation.
