T ranspedicular closing wedge ostemotomy (TCWO) has become popular in correcting thoracic and lumbar kyphotic deformity (TKD). Our study aims to evaluate the efficacy of TCWO in treating TKD of different etiologies. TCWO were performed on 25 patients with thoracic and lumbar kyphosis, of whom 10 had ankylosing spondylitis, 10 had post-traumatic thoracolumbar fractures, and 5 had tuberculosis. Mean follow up period was 24 months. Pre- and post-operative kyphotic Cobb angles and the horizontal distance between C7 and S1 in the lateral view were measured. Back pain and disability were assessed by Visual Analog Score (VAS) and Oswestry Disability Index (ODI). Postoperative complications were also recorded. Kyphotic deformity was successfully corrected and 100% osteotomic site fusion was obtained in all cases. Average operative duration was 210 min and blood loss was 1570 ml. Average correction angels were 39 degrees in ankylosing spondylitis, 37 degrees in post- traumatic, and 33 degrees in tuberculosis. The horizontal distance between C7 and S1 was 91.3 mm before the operation and 12.3 mm after the operation. Pre- and post-operative mean VAS of back pain in all cases was 7.8 and 3.0 respectively. Pre- and post-operative mean ODI was 60.5 and 30.2 receptively. Two complications were registered in two patients. Pedicle subtraction osteotomy is an effective and safe surgical method to correct thoracic and lumbar kyphosis of different etiologies
