Abstract:

BACKGROUND: It is effective in the application of posterior incision debridement, bone graft and fixation on the patients with spinal tuberculosis deformity angle more than 40°, spinal cord or cauda equina, nerve root compression and unstable.
OBJECTIVE: To analyze clinical results and biomechanical characteristics of the posterior spine dual-plane osteotomy, debridement and fusion, pedicle screw fixation for the patients of spinal tuberculosis with severe kyphosis.
METHODS: From January 2009 to January 2010, the clinical information of nine patients who accepted a bilateral posterior spinal osteotomy, debridement and fusion with pedicle screw fixation for the treatment of spinal tuberculosis with severe kyphosis was analyzed retrospectively.
RESULTS AND CONCLUSION: All the patients were safe in the perioperative period, the term of followed up was 12 (8-16) months, without the cases recurrence of tuberculosis and were all bone fusion, Cobb angle of the last follow-up and visual analogue scale score compared with preoperative score improved significantly (P < 0.01), fusion time was 8.5 (5-14) months. The clinical outcomes illustrated that the correct anti-tuberculosis treatment with the posterior spine dual-plane osteotomy, debridement and fusion, pedicle screw fixation for the treatment of spinal tuberculosis with severe kyphosis has better clinical and biomechanical effectiveness.
