Background Data: One of the worst complications of spine fracture is posttraumatic kyphosis, and beside pain and disability, new neurological deficit may develop and need surgical interference, that is challenging.Purpose: To assess the technique of pedicle subtraction osteotomy as a single posterior approach in treatment of posttraumatic kyphosis.Study Design: A prospective clinical cohort study.Patients and Methods: we recruited for this study 12 patients, 8 males and 4 females. The mean was age (31.25±9.39 years). All patients suffered symptomatic posttraumatic kyphosis and were treated surgically using pedicle subtraction technique at the Neurosurgery Department of Benha University Hospital through the period from February 2013 to April 2015. The mean period of follow up was (24.08±6.89 months). Analysis was performed with use of before-and-after pain scale, disability scale, and degree of correction. Complications and radiographic findings, and personal satisfaction from surgery were analyzed.Results: Statistically significant correction of kyphotic angle was obtained from (28.25° to 43.50°) to (3.25° to 10.25°) (P=0.002). Patients showed improvement in pain scale from (6.13 to 7.5) to (1.0 to 2.0) (P=0.002). Disability scale improved from (6.0 to 8.0) to (1.25 to 3.0) (P=0.003). No neurological complication had occurred. 91.6% of patients were satisfied from surgery.Conclusion: Pedicle subtraction osteotomy is a safe and effective technique for management of posttraumatic kyphosis, and can obtain satisfactory result. According to our results, a safe degree of 45 of correction could be obtained. (2016ESJ136)
