OBJECTIVESTo explore the long-term effects,operating opportunity,indication of anterior debridement and decompression and bone graft in treating thoracolumbar tuberculosis with paraplegia.

METHODSFrom March 2006 to September 2008, the data of 56 patients with spinal tuberculosis were retrospectively analyzed. They were 36 cases male and 20 cases female, the age in ranging from 19 to 78 years with the mean of 42.5 years; course of disease in ranging from 3 months to 4 years. The lesion level was in T11-L2, including one stage in 6 cases, two stages in 42 cases, three stages in 7 cases, four stages in 1 case. According to the Frankel grade, grade A in 5 cases, B in 25, C in 21, D in 5. Preoperative Cobb angle had 30 cases under 30 degrees, 24 cases in 30 degrees-60 degrees, 2 cases more than 60 degrees [averaged in (35.0 +/- 3.3) degrees]. The mean VAS was 7.3 +/- 2.1 preoperatively. All patients had chemotherapy for 2-3 weeks. The clinical effects were evaluated by Cobb angle, VAS, condition of Frankel grade and fusion segments.

RESULTSAll patients were followed up from 12 to 38 months with an average of 24 months. All wound obtained primary healing. The Cobb angle was(19.0 +/- 5.5) degrees immediately after operation, and lost (1.8 +/- 0.7) degrees at the follow up. The mean VAS was 1.4 +/- 0.3 postoperatively and 1.3 +/- 0.4 at final follow up. The Cobb angle and VAS significant improved in postoperatively (P < 0.05), and there was no statically difference between after operation and last follow up(P > 0.05). At 1 year after operation, all patients obstained successful bony fusion. Among 51 cases incomplete paraplegia recovered partially or completely (over Frankel D) through chemotherapy and rehabilitation training for 1-1.5 years; 5 cases of complete paraplegia had partially recovered, 3 cases from Frankel A to C, 2 cases from Frankel A to B.

CONCLUSIONBase on the chemotherapeutic effect, paraplegia reason and location, total body condition to select different operative opportunity can effectively relieve spinal compression, stabilize spinal column, correct kyphosis and promote recovery of paraplegia.
