Abstract：Objective To evaluate the efficacy and application principles of one -stage posterior intervertebral debridement, bone graft and internal fixation for the treatment of lumbosacral tuberculosis .Mte hods A retrospective analysis was performed on the clinical data of 15 cases of lumbosacral tuberculosis who were treated by surgery and got complete follow-up data.The changes of Cobb angle , the conditions of neurological function recovery , and the time of postoperative bone fusion before and after surgery were observed .Results Fifteen patients were followed up for 1~5 years, with an average of 3 years.All patients′incisions were primary healing .The postoperative X-ray films showed good bone graft and internal fixator position , and grafts gained bone fusion during 3.5 to 7 months.No loosening and fracture of internal fixator was found .Cobb angle was averagely 14 degrees .No significant loss of corrective angle was found, spinal cord function recovered well.According to Frankel grade , in 4 patients with grade C before surgery , postoperative spinal cord function restored to grade D in one case , E grade in 3cases, in 11 patients with grade D be-fore surgery, postoperative spinal cord function retured to grade E .No recurrence of tuberculosis was found.Conclu-sio n One-stage posterior intervertebral debridement , bone graft and internal fixation for the treatment of lumbosacral tuberculosis has advantages of less damage , better bone graft stability , higher fusion rate , effective correction of ky-phosis deformity , and better therapeutic results .
