Kyphotic deformity after laminectomy surgery for a gunshot wound to the spine: a case report

Spinal kyphotic deformity after spinal laminectomy or laminoplasty is more common in pediatric patients than adults. Laminectomy can lead to decreased cartilage growth, anterior wedging and posterior spinal muscle insufficiency which can result in kyphotic deformity. Herein we outline a case report of a child presenting with kyphotic deformity after receiving a spinal laminectomy to treat a penetrating spinal trauma. The 8-year-old male presented with penetrating spinal trauma following a gunshot wound and subsequently underwent L1 laminectomy and thecal sac decompression to remove the foreign body. In a follow-up examination approximately one month after surgery, imaging revealed kyphotic deformity and the patient was referred to the Rasoul-e-Akram Hospital. The patient then underwent surgical reconstruction. The postoperative computed tomography (CT) scan showed appropriate repair of sagittal balance and the patient’s symptoms gradually improved. Post-laminectomy kyphosis is a notable concern and complication in the pediatric population and can occur shortly after surgery. The following interventions can decrease the likelihood of post-laminectomy kyphosis: minimal muscle dissection and bone removal during laminectomy, avoidance of facet disruption, use of laminoplasty rather than laminectomy, postoperative immobilization/bracing and regular follow-up for early detection and treatment of any deformity.
