IntroductioN: Though rod rotation is safe and effective technique in the treatment of Adolescent Idiopathic scoliosis, adequate study on the topics with long follow-up still not available .

Method: We have select a number of patients with strict inclusion criteria to assess the translation technique of curve correction with the efficacy of side opening system for scoliosis correction & to assess patient satisfaction, correction of Cobbs angle and spinal balance . Assessment of correction of idiopathic scoliosis by pedicle screw and rod was done by reviewing the radiological and clinical outcomes .Clinical and radiological outcomes were measured in 32 consecutive patients (9 males, 23 females) with an average age of 15.0 years (range 10 to 24 years). They were followed up for 24 months. All patients underwent posterior instrumentation only with pedicle screws. More screw inserted in the concave side. X-ray evaluation done by pre-operative and 1, 3, 6 and12,18,24 months after surgery. Clinical evaluation was done by SRS questionnaire.3

Result: The mean preoperative Cobb’s angle was 58.25° , which came down postoperatively to 23.35° signifying a mean correction of 59.57%.The values of mean pre- and postoperative scores are 3.68 and 4.18, showing an improvement of 0.5 points. Superficial wound infection is the only complication.

ConclusioN: Using the axial translation technique with side-opening spinal instrumentation systems, achieved good clinical and radiological outcome for patients of AIS.

Keywords: Adolescent idiopathic scoliosis, axial translation technique, side opening pedicle screws.
