English Abstract:

  【Abstract】 Objective：To investigate the outcome of one-staged anterior debridement，autograft bone fusion and spinal reconstruction for multi-segment tuberculosis.Method：A total of 41 cases suffering spine tuberculosis and with multisegments involvement（over 3 vertebrae） between May 1998 and May 2008 underwent one-staged anterior debridement，autograft bone fusion and spinal reconstruction.The lesion ranged from C4 to S1，with 2 in cervical spine，14 in thoracic，19 in thoracolumbar，4 in lumbar and 2 in lumbosacral.7 cases were complicated with paraplegia with 4 Frankel C，2 Frankel B and 1 Frankel A.Kyphosis was noted in 21 cases.The clinical outcome was reviewed retrospectively.Result：All cases were followed up for an average of 67 months（range，12-120 months）.7 cases recovered to some degree 1 year later.The postoperative kyphosis cobb angle decreased to 11.5° compared with preoperative 23.5°，with mean loss of correction of 3.8° at final follow-up.Instrument failure was noted in 1 case and delayed union of skin incision in 2 cases.All cases got bony union with no tuberculosis recurrence.Conclusion：One-staged anterior debridement, autograft bone fusion and spinal reconstruction for multi-segment tuberculosis is reliable.
