Pedicle Subtraction Osteotomy in Local Kyphotic Deformity: An Institutional Study

Kyphotic deformity of spine is a debilitating condition of the spine occurring most commonly as a consequence of traumatic spinal injury. In developing countries, Pott's spine also accounts for kyphosis in significant number of patients. Kyphosis is a growing concern for treatment to the patient either due to the progressive neurological deficit or mechanical back pain due to altered spinal biomechanics. Dorsal spinal ostetotomies can readily attend to these treatment goals with the added advantage of being a single approach to both the anterior and posterior compartments and lack of dependency on an anterior device. We present our experience with pedicle subtraction osteotomies in our institution in this study.45 patients with kyphotic deformity were addressed with this procedure, along - with posterior fusion and were assessed in regards to the degree of correction of kyphotic deformity, neurological improvement and post - operative complications. We conclude that with proper anatomic, functional and biomechanical knowledge of the spine, this procedure could provide a one - step solution to all sorts of kyphotic deformities with limited complications.
