Summary

Routine radiographs are commonly obtained after spinal fusion surgery to monitor postoperative evolution and detect complications. However, the actual contribution of these radiographs to clinical decision-making remains unclear. This retrospective cohort study evaluates the frequency and clinical impact of routine postoperative radiographs in patients undergoing spinal fusion surgery at University Hospitals Leuven.

Detailed description

Routine radiographs are commonly obtained after spinal fusion surgery to assess implant position, fusion progress, and potential complications. Yet, their actual contribution to patient care remains uncertain, and routine use may expose patients to unnecessary radiation and increase healthcare costs. In this retrospective cohort study, the investigators will evaluate the clinical utility of routine radiographs during the first postoperative year after spinal fusion surgery at University Hospitals Leuven (2011-2021). The investigators will review each follow-up visit to record the clinical course, radiographic findings, and whether these influenced further diagnostic tests or therapeutic interventions. The investigators will primarily assess how often radiographs lead to a change in management. Secondary analyses will determine the proportion of abnormal versus normal radiographs, the relationship between clinical course and imaging results, and whether demographic or surgical factors predict radiographic utility. By analyzing nearly 1,000 patients and more than 2,800 visits, the investigators will provide one of the most comprehensive evaluations of routine postoperative radiographs to date, aiming to guide more efficient, evidence-based follow-up strategies.
