A Penetrating Lumbar Spine Injury With Misleading Neurological Symptoms

Penetrating spinal injuries require specific neurosurgical attention. To date, there are no guidelines regarding emergency neurosurgical management of such injuries and the decision whether to operate is made individually, based on the neurological examination and the analysis of any imaging available. We report the case of a 22-year-old patient who sustained two gunshots in the thighs and one in the lumbar spine. Clinical examination revealed neurological deficit in both legs prevailing on the right side. Discussion between the radiologist and the neurosurgeon concluded to an injury to the left S1 nerve root within the spinal canal, and to the right sciatic nerve. Thus, there was no need for a decompressive laminectomy. In the light of the current literature, penetrating spinal injuries rarely require an extensive surgical exploration; indications for such a procedure include incomplete neurological deficit with persistent neurological compression, cerebrospinal fluid leakage, and obvious instability. Furthermore, penetrating spinal injuries are rarely encountered, even for military neurosurgeons. Their surgical management and especially the need for laminectomy, stabilization, and dural sac watertight closure are still a matter of debate. An expert consensus statement would give food to surgeons facing penetrating spinal injuries.
