One stage posterior vertebral column resection for the treatment of thorciclumbar tuberculosis with kyphotic deformity / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To evaluate the clinical outcome of one stage posterior vertebral column resection in patients with spinal tuberculosis combined with kyphotic deformity.@*METHODS@#Thirty-six patients with spinal tuberculosis combined with kyphotic deformity underwent posterior one-stage vertebral column resection reducing tension on the spinal cord from 1998 to 2006. The patients were mobilized with a thoracolumbar orthosis for 3 months. All patients had a minimum of a 2-year follow-up, and clinical examinations and radiographs were obtained at 6-month intervals.@*RESULTS@#No perioperative mortality occurred. The average duration of surgery was 208 (145 approximately 385) min. The kyphotic Cobb angle improved from the preoperative average of 57.2 degree(17 degree approximately 86 degree) to a postoperative average of 8.9 degree(-6 degree approximately 27 degree). The average horizontal distance between C(7) and S(1) was 13.6 (8 approximately 19) mm preoperatively and 3.6 (-11 approximately 9) mm postoperatively. Nineteen patients had preoperative neurological deficits. Of them, 89.5% (17/19) showed a postoperative neurologic improvement. Perioperative complications occurred in 3(8.5%) of the 36 patients with pneumonias and superficial infections. Twenty-five patients (69.4%) showed radiographic evidence of solid fusion in the follow-up examinations. In the follow-up, 25% (9/36) patients rated their results as excellent, 66.7% (24/36) as good, 2 as fair, and 1 as poor.@*CONCLUSION@#One stage posterior vertebral column resection for the treatment of spinal tuberculosis with kyphotic deformity is safe and effective. Because this procedure is highly technical, the surgeon must be familiar with the pathoanatomy and the operation must be carefully done.
