Abstract
Of 112 patients who entered the Medical Research Council's prospective study on the surgical management of spinal tuberculosis, 105 were available for review at a mean follow-up of 15.3 years postoperatively. All these patients were age 18 years or more at the time of surgery. Seventy-one patients had radical surgery; the remaining 34 underwent debridement surgery. The longitudinal changes in spinal deformity were evaluated using kyphus and deformity angles from lateral spinal radiographs obtained at preoperative evaluation, postoperatively at 6 months, 1 year, and 5 years, and at final follow-up. The mean kyphos and deformity angles showed correction after radical surgery at 6 months' evaluation; thereafter there were minimal variations up to final follow-up. Those who underwent debridement surgery showed an increase in these angles at 6 months postoperative evaluation; thereafter there were practically no changes in thoracic and thoracolumbar tuberculosis, whereas in lumbar tuberculosis there was spontaneous correction from 1 year post-surgery onward. The changes in mean kyphos and deformity angles at 6 months postoperative evaluation from their preoperative values were significantly different between the two surgical groups, where radical surgery produced better correction. Thus, the choice of surgery--radical or debridement--is important in determining the fate of spinal deformity in the management of tuberculosis of the spine.
