Optimizing lordosis preservation in monosegmental lumbar spondylodesis: evaluating the efficacy of a novel noninvasive technique using intraoperative hip hyperextension.

ABSTRACT:

Background

Loss of lumbar lordosis after spinal fusion can lead to complications such as chronic low back pain, abnormal sagittal balance, and accelerated adjacent segment degeneration. This study aims to evaluate a novel intraoperative positioning technique for lumbar spondylodesis, involving hip hyperextension in the prone position with an inflatable bladder under the thigh to preserve lumbar lordosis.

Materials and methods

This prospective, pilot, interventional study included 100 patients undergoing monosegmental lumbar fusion at L4 or L5. Patients with degenerative disc disease and no prior spine surgery were enrolled. Lateral X-rays were obtained preoperatively, intraoperatively, and postoperatively, measuring sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI),
