Surgical Treatment of Kyphosis in Children in Healed Stages of Spinal Tuberculosis

BACKGROUNDVery less literature focuses on the treatment of kyphosis in healed stages of spinal tuberculosis (TB), especially in children. The purpose of this study was to evaluate the outcomes of anterior release, decompression, deformity correction, and instrumented fusion, followed by posterior osteotomy, deformity correction, and pedicle screw instrumented fusion, which is used to treat kyphosis in children in healed stages of spinal TB. METHODSSixteen children with kyphotic deformity of the spine in healed stages of TB underwent anterior release, decompression, deformity correction, and instrumented fusion, followed by posterior osteotomy, deformity correction, and pedicle screw instrumented fusion between 2003 and 2007 with at least 2 years of follow-up. Radiologic assessment including the angle of kyphosis and scoliosis, and neurologic status using the modified Frankel grade were analyzed before surgery, after surgery, and at the last follow-up. Fusion was evaluated on flexion-extension lateral radiographs. RESULTSGood cosmetic results were achieved in all patients. Neurologic improvement was shown in all 4 patients with paraplegia. The mean preoperative angle of kyphosis was 55.8 degrees that reduced to 21.7 degrees, postoperatively. The difference in the mean angle of kyphosis was statistically significant (P
