Introduction
Between 1997 and 2006, we treated 11 patients with tuberculotic spondylitis and 19 with pyogenic spondylitis using a two-staged operation (posterior spinal instrumentation, followed by anterior debridement and fusion).
Method
We compared changes in inflammatory reactions, postoperative complications, organisms obtained during anterior debridement, neurological status, bone union, and suppression of the infection between the patients with tuberculotic and pyogenic spondylitis.
Patients
All patients in both groups achieved bone union and suppression of the infected sites. Decreases in C-reactive protein and erythrocyte sedimentation rate were significantly slower in the patients with tuberculotic spondylitis. Positive bacterial cultures at the second anterior debridement were obtained from 26% of patients with pyogenic spondylitis and 55% of patients with tuberculotic spondylitis. Frankel types improved in 57% of patients, but there were no differences in neurological improvement. The efficacy of the two-staged operation did not differ between the patients with pyogenic and tuberculotic spondylitis.
Results
Although the baselines were different, there were no significant differences in relative operating parameters, neurological improvement, or postoperative complications between the two groups. At the final follow-up, all patients finally achieved suppression of spinal infection and solid bone fusion in both groups, although the decline in inflammatory parameters was slower in the T group than in the P group.
