Spinal cord injury
During a typical year, there are about 12,000 spinal cord injuries in the US or 40 cases per million persons per year.
The most common causes of spinal cord injuries are
Motor vehicle crashes (48%)
The remainder of spinal cord injuries are attributed to assault (12%), sports (10%), and work-related accidents. About 80% of patients are male.
Vertebral injuries may be
- Fractures, which may involve the vertebral body, lamina, and pedicles as well as the spinous, articular, and transverse processes
- Dislocations, which typically involve the facets
- Subluxations, which may involve ligament rupture without bony injury
In the neck, fractures of the posterior elements and dislocations can damage the vertebral arteries, causing a syndrome resembling a brain stem stroke.
