Management of non-missile penetrating spinal injury

Review of the literature with case illustration. Non-missile penetrating spinal injury (NPSI) represents a small subset of spinal cord injuries at tertiary trauma centers and is comprised mostly of knife violence. Strict guidelines for the management of penetrating spinal cord injury remain elusive given the variability of mechanisms, rarity of clinical experience, and paucity of prospective studies. A review of the literature was conducted by search of the National Library of Medicine (PubMed) in the English language through June of 2018. Additional articles were culled from the reference lists of the included series. Eleven case series totaling 1007 patients, along with 21 case reports, were identified. In summary, magnetic resonance imaging (MRI) may be beneficial in assessing incomplete or progressive spinal injuries and can be considered with retained foreign bodies in select cases. Forty-eight hours of antibiotic prophylaxis is likely sufficient to prevent infection. Puncture wounds should be debrided, washed, and closed. Retained foreign bodies should be removed in the operating room and often require laminectomy. Early intervention is preferred. Non-missile penetrating spinal injury has a higher likelihood of neurologic recovery as compared to other traumatic spinal injuries.
