Degenerative Scoliosis Clinical Trial
Official title:
Correlation Among Standing-sitting Sagittal Spinal Alignment, Paravertebral Muscle and Postoperative Clinical Outcomes in Patients With Adult Degenerative Scoliosis
This is a prospective single-center study. Patients with adult degenerative scoliosis are prospectively enrolled and followed. All patients will take standard standing and sitting posteroanterior and lateral whole spine X-ray and lumbar MRI examination before and after surgery. Functional evaluation and radiographs were assessed preoperatively and postoperatively.This study will focus on the correlation among standing-sitting sagittal spinal alignment, paravertebral muscle and postoperative clinical outcomes in patients with adult degenerative scoliosis.
