Analyzing mechanical complications in degenerative lumbar scoliosis surgery

Clinical Study of Imaging and Endoplant-related Mechanical Complications After Long Segment Fixation and Fusion of Degenerative Lumbar Scoliosis (DLS)

Observational Peking University Third Hospital · NCT04960423

This study looks at patients with degenerative lumbar scoliosis who had surgery to see how often they experience complications and what might cause them.

What this trial studies

This observational study aims to retrospectively analyze patients with degenerative lumbar scoliosis who underwent long segment fixation and fusion surgery. It focuses on collecting and examining patients' basic data, surgical details, and imaging data from preoperative, immediate postoperative, and follow-up periods. The study seeks to identify the incidence of distal mechanical complications and their risk factors, as well as their relationship with clinical symptom scores. The findings are intended to guide clinical decision-making for surgical operations.

Who should consider this trial

Good fit: Ideal candidates are patients aged 45 and older with degenerative lumbar scoliosis who have undergone long segment fixation and fusion surgery.

Not a fit: Patients with idiopathic scoliosis, neuromuscular scoliosis, or a history of spinal surgery or trauma may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes and reduce complications for patients undergoing surgery for degenerative lumbar scoliosis.

How similar studies have performed: While there is limited research specifically on this topic, similar studies on mechanical complications in spinal surgeries have shown varying degrees of success.
