Perioperative complications of posterior transpedicular osteotomy for patients with spinal deformity / 中华骨科杂志

ABSTRACT

Objective To analyze the perioperative complications of posterior transpedicular osteotomy (wedge osteotomy and total vertebral osteotomy) for patients with spinal deformity.Methods From January 2007 to December 2011,73 patients with spinal deformity underwent posterior transpedicular spinal osteotomy (wedge osteotomy and total vertebral osteotomy).Among them,30 patients,including 8 males and 22females,aged from 8 to 68 years (average,40.7 years),presented with at least one perioperative complication.There were 10 cases of scoliosis,9 cases of kyphoscoliosis and 11 cases of kyphosis.Twenty two patients underwent total vertebral osteotomy,and 8 patients underwent wedge osteotomy.A retrospective analysis on perioperative complications of 30 patients was performed.Results Except 1 patient dying of hemorrhagic shock after operation,29 patients were followed up for 6 to 61 months (average,17.2 months).The total perioperative complication rate was 41.1％.Neurological complications occurred in 16 patients (21.9％),bleeding complications in 2 patients (2.7％),dural injury in 6 patients (8.2％),postoperative cerebrospinal fluid leakage in 4 patients (5.5％),wound infection in 4 patients (5.5％) and pleural effusion in 4 patients (5.5％).Conclusion Posterior transpedicular osteotomy is an effective surgical technique for spinal deformity.However,perioperative complications are common,including nerve injury,bleeding,dural injury,wound infection and so on.Among them,nerve injury and bleeding are most common.
