[Function reconstruction of anterior and middle column in thoracolumbar spinal tuberculosis by one-stage anterior radical debridement].
OBJECTIVE
To summarize the effect of one-stage anterior debridement of infection in function reconstruction of anterior and middle column for the treatment of thoracolumbar spinal tuberculosis.


METHODS
From January 2001 to January 2007, 65 patients with thoracolumbar spinal tuberculosis were treated with one-stage anterior debridement, decompression, autogenous bone grafts and internal fixation. There were 43 males and 22 females with an average age of 40.2 years (range, 19-64 years), including 18 cases of thoracic tuberculosis (T(4-l0)), 44 cases of thoracolumbar tuberculosis (T11-L2) and 3 cases of lumbar tuberculosis (L(3-5)). The disease course was 3 months to 10 years (median 10 months). One segment was involved in 7 cases, two segments in 54 cases and three segments in 4 cases. In 14 cases with spinal cord injury, there were 5 cases of grade C and 9 cases of grade D according to Frankel classification. The kyphotic Cobb angle was 20-65 degrees (41 degrees on average).


RESULTS
The operative time was 120-210 minutes (170 minutes on average), and the blood loss was 300-1500 mL (600 mL on average). Fifty-eight patients were followed up for 1-6 years (23 months on average). Abscess occurred in 2 cases at 40 days and 3 months, and healed after symptomatic management. The other incisions achieved healing by first intention. The X-ray films showed bony fusion 4-12 months (6 months on average) after operation. No tuberculosis recurred. At 12 months after operation, pain disappeared, and there were 7 cases of grade D and 7 cases of grade E according to Frankel classification. The kyphotic Cobb angle was 0-33 degrees (24 degrees on average), showing statistically significant difference (P < 0.05) when compared with preoperation.


CONCLUSIONS
Early reconstruction of load-bearing function and stability of anterior and middle column in the treatment of spinal tuberculosis is great significant. The application of one-stage anterior surgery with debridement, decompression, autogenous bone grafts and internal fixation in the operative treatment of thoracolumbar tuberculosis is safe and effective after a rigorous anti-tuberculosis treatment.
