Patient-based outcomes analysis of patients with single torsion thoracolumbar-lumbar scoliosis treated with anterior or posterior instrumentation: an average 5- to 9-year follow-up study.

摘要

INTRODUCTION: Since the advent of single, stiff rod anterior instrumentation, and now dual rod anterior instrumentation, most thoracolumbar-lumbar scoliosis is treated with an anterior approach. We have previously reported a retrospective comparison of patients with single torsion thoracolumbar-lumbar scoliosis treated with either anterior or posterior instrumented fusion. The purpose of this study is to examine the patient-based outcomes in this cohort of patients at an average of 5 years (anterior instrumentation) and 9 years (posterior instrumentation). MATERIALS AND METHODS: Inclusion criteria were as follows: 1) single torsion thoracolumbar or lumbar curve of
