Diagnostic value of CT for acetabular trauma

Objective:To evaluate the diagnostic value of CT scan for acetabular trauˉma.Methods:25patients with acetabular trauma,who underwent both plain film and CT exˉamination,were included in our study.Results:Among25patients12were right acetabular trauma,10were left acetabular trauma,3were bilateral acetabular trauma.There were15patients with acetabular fracture:4patients with fracture of posterior wall of acetabulum,3patients with anterior wall fracture,5patients with posterior column fracture,2patients with anterior column fracture,1patient with transverse fracture.9patients with acetabular fracture had positive sign on plain film.The detective rate was60%for plain film and100%for CT scan.Conclusion:CT can show the overall anatomic character of acetabulum directly and can offer more useful information than plain film.CT was a helpful imaging modality for estimating the stability of fracture and selecting rational therapy.
