The REESE study is looking at information from past spine surgeries to learn how often screws placed at the top of a spinal fusion become loose over time. Researchers will review existing medical records and X-rays from adults who have already had thoracolumbar spinal fusion surgery. The study will also look at factors that may increase the risk of screw loosening and whether it leads to additional complications or surgeries. No new procedures, treatments, or patient visits are required because the study uses information that has already been collected during routine medical care.
The REESE (Retrospective Evaluation of Upper Instrumented Vertebrae Screw Loosening Following Spine Surgery) study is a multicenter, retrospective chart review that aims to determine the rate of screw loosening at the upper instrumented vertebra (UIV) following thoracolumbar spinal fusion surgery and identify associated risk factors. Up to 400 patients from up to 10 U.S. sites will be included. Eligible patients must be adults who underwent thoracolumbar fusion with bilateral UIV screws and have at least 12 months of postoperative imaging follow-up.
Inclusion Criteria: * ≥ 18 years of age at the time surgery * Underwent thoracolumbar spinal fusion with bilateral screws at the UIV 1. Construct \<4 levels ending at the sacrum may be treated with or without pelvic fixation 2. Constructs ≥4 levels ending at the sacrum must include pelvic fixation 3. Constructs not ending at the sacrum may be included * Patient must have a minimum of 12-month follow-up including imaging (AP and lateral x-rays) Exclusion Criteria: * Treated for high grade (grade III, IV, or V) spondylolisthesis * Diagnosed with primary or metastatic tumor involving th…
