However in severe and rigid curvatures, combined anterior and posterior fusion is generally required. In this study we have aimed to evaluate the efficacy of posterior only instrumentation in severe thoracolumbar scoliosis clinically and radiologically and compare these results with the literature.

MATERIAL and METHODS: In this retrospective study, 29 consecutive patients with severe idiopathic scoliosis who underwent posterior only instrumentation and fusion between March 2003 and February 2011 were included the study. Radiological evaluation was performed with preoperative, postoperative and folllow up standing AP and lateral x-rays. Clinical evaluation was made with shoulder balance and trunk shift.

REAULTS: Major curve magnitude decreased to 24,1º and compensatory curve magnitude decreased to 12.20º at postoperative period. There was no significant difference in sagittal plane angles. Major curve correction rate was %68,65 in screw only instrumentation and % 65 in hybrid instrumentation.

CONCLUSION: Transpedicular screw instrumentation in severe IS is a safe and effective method in proper hands when flexibility of the curve evaluated accurately in preoperative period. Keywords : Scoliosis, Posterior vertebral fusion, Anterior vertebral fusion
