Dynamic stress fluoroscopy with the patient under general anesthesia has been advocated as a clinical measure of hip stability and congruity in patients with a posterior wall acetabular fracture. The purpose of this study was to establish the predictive value of the dynamic stress fluoroscopic examination for these fractures by evaluating clinical and radiographic outcomes after nonoperative treatment of fractures found to be stable with this examination.
21 consecutive patients with an acute posterior wall fracture of the acetabulum who were shown to have a stable hip joint by dynamic stress fluoroscopy while they were under general anesthesia were treated nonoperatively. At the time of follow-up, the patients underwent clinical and/or radiographic evaluation.
Hip joint stability determined with dynamic stress fluoroscopy with the patient under general anesthesia after a posterior wall acetabular fracture is predictive of hip joint congruity, an excellent radiographic outcome, and a good-to-excellent early clinical outcome after nonoperative treatment.
Level of evidence: Prognostic Level IV. See Instructions to Authors for a complete description of levels of evidence. Copyright remains with the authors and publisher.
