Background:
Gunshot wound (GSW) injuries are among the leading causes of penetrating spinal column injury (pSI). Patients with pSI often have concurrent polytrauma that complicates management.
Methods:
We retrospectively reviewed charts between January 2012 to June 2018 at an urban Level 1 trauma center and analyzed bracing and surgical indications, antibiotic and magnetic resonance imaging (MRI) use, and patient outcomes.
Results:
We identified 100 patients with pSI with an average age of 27.2 (range, 15-58) years. Five patients had knife injuries and 95 suffered GSW. Polytrauma occurred in 90% of patients with an average of 3.39 bullets per patient (range, 1-23). Fourteen patients underwent either decompressive surgery (n = 8) or decompression and fusion (n = 6). Thirty-five patients were externally braced. A total of 43% of patients presented as American Spinal Injury Association-A compared with 26% who were intact. Although 14 patients received prophylactic antibiotics for retained bullets or durotomies, only 2 patients had postoperative wound infections and 4 had extraspinal infections from retained bullets. All inpatient mortalities (n = 5) were patients with cervical pSI. Thirteen patients with GSW obtained MRI scans without complications. Among our cohort, only 65 patients had follow-up with a median follow-up period of 1.25 (range, 1-60) months.
Conclusions:
Management of pSI in urban trauma centers is complex, as these victims routinely have polytrauma that takes precedence. Indications for surgical intervention are narrow and secondary to surgery for polytrauma. External bracing may be overutilized. The efficacy of prophylactic antibiotics remains unclear. MRI can contribute valuable information but is limited by uncertainty regarding bullet compatibility. Lack of follow-up limits the study of this population.
