Radiographic outcome of adolescent idiopathic scoliosis surgical correction with posterior spinal fusion using pedicle screw and rods fixation.
J Surg Pak Jan ;16(3):118-22.

Objective To evaluate the correction of deformity as measured by Cobb’s angle with posterior spinal instrumentation and fusion (PSIF), by using rods and pedicle screw along with autologous bone graft in adolescent idiopathic scoliosis (AIS). Study design Descriptive case series. Place & Duration of study Department of Orthopaedics and Spine Surgery Postgraduate Medical Institute, Hayatabad Medical Complex Peshawar, from January 2007 to April 2011. Methodology Patients of aged more than 10 years of either sex were included in the study. All patients were managed by posterior spinal fusion using pedicular screws and rod and then evaluated by standing anteroposterior and lateral radiographs post operatively. The data was analysed with SPSS version 10. Results There were a total 18 patients with 14 (77.8%) females and 4 (22.2%) males. Mean age was 17 years (range 13-30 years) . The preoperative Cobb angle was 450 minimum, 1200 maximum (average 700) which was corrected to 50 minimum, 650 maximum and 200 average postoperatively. Total correctness achieved was 250 minimum, 700 maximum and 500 average. Conclusion Pedicle screw construct can result in better correction and less frequent implant failures in idiopathic scoliosis.
