Summary

This study examines how well computed tomography (CT) imaging performed during spine surgery - known as intraoperative CT - can detect instability in the lower (lumbar) part of the spine. Spinal instability means that the bones of the spine move more than they normally should, which can contribute to pain and may affect the outcome of surgery.

Before surgery, doctors usually check for this instability using X-rays taken while the patient bends forward and backward. These X-rays do not always show instability clearly. During surgery, the patient lies face down and the muscles are fully relaxed, which can change how the spine appears on imaging.

The purpose of this study is to learn whether CT images taken during surgery can identify signs of lumbar spinal instability as reliably as standard imaging performed before surgery, and whether they can reveal signs of instability that were not visible beforehand. To do this, the researchers will review imaging and clinical information from adults who are undergoing surgery for degenerative (wear-related) conditions of the lower spine.

This study does not change a patient's surgery or treatment. It only analyzes imaging and clinical information that are already part of standard care. The findings may help guide imaging and surgical decisions in lumbar spine surgery in the future.
