Deskripsi

Study Design Retrospective case series. Purpose Describe the technique and evaluate the outcome of apical vertebral column resection (VCR) with sagittal rotation and anterior opening and posterior closing (AOPC) maneuver for correction of severe post-tubercular kyphosis (PTK). Overview of Literature The surgical procedures described for the correction of PTK are VCR, pedicle subtraction osteotomy, transpedicular decancellation osteotomy, and closing-opening osteotomy. Methods We retrospectively evaluated 21 patients who had been operated on with single stage apical VCR with AOPC maneuver. Radiographs were obtained before surgery and at regular follow-up intervals. These were used to calculate the angle of kyphosis. Back pain was rated using the Visual Analog Scale (VAS) and neurological status was graded using Frankel grading. Radiological outcome was assessed by the improvement in the angle of kyphosis and fusion following surgery. Neurological status was assessed using Frankel grading. Results The study included eight males and 13 females with a mean age of 21.9 and average follow-up time of 30.4 months. The average number of vertebral bodies destroyed was 2.57. Kyphosis was improved from a mean of 68.42°±13.23° preoperative to 8.71°±4.58° postoperative. The average correction achieved was 87.10%. Preoperative VAS score improved from a mean of 6.38±0.92 preoperative to 1.38±0.49 postoperative. No patients had any sign of neurological deterioration. Seven out of eight patients with a preoperative neurological deficit improved following surgery. Two patients developed superficial wound maceration, one had persistent postoperative hypotension, and the other developed hemothorax. All patients recovered fully without a need for additional surgery. Conclusions Single stage simultaneous anterior column lengthening and posterior column shortening is an effective method for surgical correction of severe PTK.
