Background: 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.
Objective: 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 of 12 patients (8 males and 4 females) were included, a mean age (31.25±9.39 years), with symptomatic posttraumatic kyphosis who were treated surgically using pedicle subtraction technique at the Neurosurgery Department of Benha University Hospital through the period from February 2013 to April 2016. The mean period of follow up was (24.08±6.89months).
Methods: 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: Twelve patients were studied, eight males (66.7%) and four females (33.3%) with mean age 31.25±9.4 months (ranging from 18y to 48y), and they were followed up for a period ≥18 months with a mean of 24.08±6.89 months (ranging from 18 to 36 months) 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), and also disability scale from (6.0 to 8.0) to (1.25 to 3.0) (P=0.003). No neurological complication had occurred, and 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 very satisfactory result. According to our results, a safe degree of 45 of correction could be obtained.
