Intervertebral Disc Degeneration in Long-Term Postoperative Patients with Adolescent Idiopathic Scoliosis: MRI Evaluation 34-51 Years after Surgery and its Changes during Middle and Older Age for an Average of 6.9 Years.

ABSTRACT:

Introduction

This study aimed to identify factors associated with intervertebral disc degeneration (DD) in adolescent idiopathic scoliosis (AIS) patients who reached middle and older age after surgery.

Methods

A total of 252 AIS patients who underwent spinal fusion surgery between 1968 and 1988 were included in this survey-based study. Patients with a mean follow-up period of 40.9 years were evaluated through lumbar spine magnetic resonance imaging (MRI), radiographic assessments, and patient-reported outcome measures (PROMs). DD was evaluated using the Pfirrmann grading system. Various factors, such as surgical levels, sagittal alignment, and PROMs, were analyzed for their association with DD.

Results

Among the 21 participants who underwent both previous (conducted f
