An Evaluation of Correction of Idiopathic Kyphoscoliosis by Axial Translation Technique with Pedicle Screw and Rod
As sufficient study not available in this subcontinent about correction of idiopathic kyphoscoliosis by axial translation technique, a group of patients of Adolescent Idiopathic Scoliosis (AIS) was selected to evaluate the outcome of rod rotation technique. The curve correction with more screw on the concave site was assessed, patient satisfaction and correction of cobb angle. Post operative radiological and functional outcome were assessed. Twenty consecutive patients (8 males, 12 females) with an age range from 10 to 24 years. Post operatively all were followed-up for 18 months. All patients were under went pedicle screw instrumentation through posterior approach. More screw inserted in the concave side. X-ray evaluation done by pre-operative and 1, 3, 6 ,12 and 18 months after surgery. Scoliosis Research Society (SRS) questionnaire was done for clinical evaluation. Radiological evaluation done by preoperative cobb angle was significantly reduced in postoperative period. The mean postoperative SRS scores were improved from 3.38 to 4.13. These results were statistically significant and so it may be concluded that the axial translation technique with more screw in the concave side is ideal technique with good postoperative outcome both clinically and radiologically.
