Single-stage posterior vertebral column resection and internal fixation for old fracture–dislocations of thoracolumbar spine: a case series and systematic review

摘要

PurposeTo evaluate the efficacy of single-stage posterior vertebral column resection for old thoracolumbar fracture–dislocations with spinal cord injury.MethodsFrom January 2007 to June 2013, twelve male patients (average age, 32.6?years; range 19–57?years) with old fracture–dislocations of the thoracolumbar spine and spinal cord injury underwent single-stage posterior vertebral column resection and internal fixation. All patients were assessed for relief of the pain and restoration of neurologic function. Postoperative Cobb angle was measured and bone graft fusion was evaluated by X-ray. A systematic review of 25 studies evaluating surgical management of thoracolumbar fractures with spinal cord injuries was also performed.ResultsFrom our case series, six of the nine patients with Frankel grade A had significant improvement in urination and defecation after surgery. The three patients with Frankel grades B and C had progression of 1–2 grades after surgery. Bony fusion was achieved and local back pain was relieved in all patients after surgery. From our systematic review of 25 studies, the majority of patients had improved back pain, the postoperative kyphotic angle was significantly reduced compared with pre-operative kyphotic angle.ConclusionSingle-stage posterior vertebral column resection and internal fixation for old thoracolumbar fracture–dislocations is an ideal treatment allowing for thorough decompression, relief of pain, correction of deformities, and restoration of spinal stability.Level of evidenceIV...
