Background:
Spine injuries after gunshot wounds are thought to be rare among asymptomatic patients. The occurrence of spine injuries among asymptomatic patients with gunshot wounds was studied to determine the necessity for mandatory spine immobilization and radiographic imaging.
Methods:
In this retrospective cohort study, initial physical examination, radiographic findings, and final diagnosis and treatment were reviewed. Patients were included if they were admitted to the authors’ level 1 trauma center with gunshot wounds to the head, neck, or trunk during a 10-year period. Spine injuries were considered “significant” if the injury was associated with spinal cord injury or required spine-related surgical procedures or prolonged spine immobilization. Spine injuries were defined as “unsuspected” if there were no neurologic findings at admission.
Results:
During the study period, 2,450 patients who survived more than 24 hours were admitted with gunshot wounds to the trunk, neck, or head. Of these patients, 244 (approximately 10%) had spine injuries, and 228 of them had complete records. Two thirds of the spine injuries were found to be significant, requiring surgery or prolonged immobilization, and 13% were unsuspected.
Conclusions:
Spine injuries without neurologic signs are not uncommon among patients with gunshot wounds. Complete radiographic spine imaging is therefore recommended to ensure that spine injuries are not missed in this population.
