BackgroundGunshot injuries are one of the most common causes of the penetrating injuries of the spine. The victims of these injuries usually have neurologic deficits. Percutaneous endoscopic lumbar surgery is one of the most popular surgical spine interventions. We report a case with incomplete radiculopathy due to shrapnel located in L5 foramen that was removed by percutaneous endoscopic technique.Case DescriptionA 23-year-old man sustaining a gunshot injury penetrating to the abdomen presented to our hospital. His first examination revealed a single gunshot wound with entry hole in the left low lumbar region without exit hole and right lower abdominal quadrant tenderness. Plain radiographs and computed tomography showed a bullet in the abdomen and left L5 transverse process fracture and shrapnel in L5 foraminal zone. The bullet was removed by abdominal surgeons without any surgical plan for the shrapnel in the foramen. He was referred to our clinic 3 weeks after discharge. Without any further neurologic deterioration, he had uninterrupted severe pain that was mostly unbearable during the night. Despite gradually increasing dosages of different drugs, his pain relief was insufficient. Percutaneous transforaminal endoscopic removal of the shrapnel was planned.ConclusionsDespite the absence of a universally approved algorithm in the treatment of spinal gunshot injuries, endoscopic technique can be kept in mind for a minimal access and invasiveness in case of indication for removal. With experience in endoscopic procedures and familiarity with surgical anatomy, the treatment of this unique case was completed successfully.Copyright © 2020 Elsevier Inc. All rights reserved.
