Computerised tomography after posterior dislocation of the hip

Abstract

We have reviewed 19 consecutive patients admitted to the Odense University Hospital after traumatic dislocation of the hip. We aimed to perform computerised tomography as soon as possible after closed reduction; this was accomplished in 15 patients. The CT scans revealed intra-articular fragments of bone in five hips, and fractures of the femoral head or acetabulum in six. In two cases the CT scans excluded fractures or intra-articular fragments which had been suspected on conventional radiography. CT scanning is a useful diagnostic tool in traumatic dislocation of the hip; we consider that it makes an important contribution to management.
