Fractures of the acetabulum: classification and surgical approaches for open reduction. We conclude that roof arc measurements are useful to further characterize patients with acetabular fractures. CT estimation of the roof arc measurement also was different between the two groups. Patients treated operatively for their acetabular fractures had a smaller roof arc measurement, as measured on radiographs, when compared to those patients treated nonoperatively. The clinical record for each patient was reviewed to determine whether the patient had been treated conservatively or surgically. Roof arc measurements were performed on radiographs and CT scans. Thirty-five patients with transverse or T-shaped acetabular fractures were reviewed. We also studied the utility of these roof arc measurements for predicting surgical vs. We present the method for measuring the roof arc on radiographs and estimating this arc on CT scans. For patients with acetabular fractures, the extent to which a fracture involves the weight-bearing dome has been estimated with the “roof arc” measurement obtained on radiographs and computed tomographic (CT) studies.
