Objective To investigate the clinical therapeutic effect of general spine system(GSS) short-seg-ment posterior fixation for the thoracolumbar spine fracture.Methods Totally 47 patients with thorocalumbar fracture were retrospectively analyzed from May 2006 to July 2009,which were operated by general spine system short-segment posterior fixation,preoperative and postoperative Cobb angle,front and rear margin height ratio of vertebral body and the recovery of neural function were measured respectively.Results All patients were followed up,in 47 patients with thoracolumbar burst fracture,kyphosis deformity were corrected satisfactorily in X-ray visibly,vertebral body height got good recovery.2 cases occurred loss of corrective angle less than 5% after operation,in Frankel function classification.B～D classes showed significant improvement( at least one grade),A grade improved to B in 1 case,no serious complications occurred.Conclusion GSS short-segment posterior fixation was a safe and effective treatment method for thoracolumbar fracture.It can restore height and physiological curve of injuried vertebral body,contribute to recovery on neural function.
