    Abstract:
    OBJECTIVE: To explore an effective and reasonable surgical strategy for active spinal tuberculosis with severe kyphotic deformity (kyphotic angle >or= 45 degrees). METHODS: From January 2004 to January 2008, 30 consecutive patients of active spinal tuberculosis complicated with significant angulation were enrolled in this study, including 8 male and 22 female. The average age was 35 years (range, 7 - 60 years), with average angle of kyphosis of 58 degrees (range, 45 degrees - 70 degrees). There were 28 patients complicated with intraspinal abscess, of which 10 patients presented with incomplete paraplegia. According to the Frankel's scoring system, there were 2 patients with Frankel Grade B, 6 with Grade C, 2 with Grade D. After antituberculous chemotherapy (HREZ) for at least 2 weeks, all patients underwent posterior multiple-level pedicle screw instrumentation and kyphotic correction, and then received anterior debridement, decompression and supportive bone grafting, all of which were completed in the same day. The postoperative standardized chemotherapy was 6HREZ/6-12HRE. The angle of kyphosis, curve correction after surgery, and recovery of paraplegia were analyzed. Fusion status and erythrocyte sedimentation rate were recorded to determine the presence of active disease. RESULTS: Operative time was 4 to 6 hours (average 5.2 h), blood loss was 600 to 900 ml (average 760 ml). No perioperative severe complications occurred. The kyphotic angle was corrected to 0 degrees - 10 degrees, and the maximum corrected angle was 65 degrees . The average follow-up duration was 18 months (range, 12 - 48 m). All patients showed evidence of solid fusion and healing of the active disease at 6 months follow-up. Neurologic deficits were improved: 2 patients from B to D, 6 patients from C to E, 2 patients from D to E. No recurrence of the tuberculosis infection or instrumentation failure happened at final follow-up. CONCLUSION: Combined posterior instrumentation and anterior debridement, fusion surgery in one stage is proved to be successful in treating spinal tuberculosis, correcting the kyphosis, and providing solid fusion.
