Posterior Hip Dislocation


Diagnosis

Diagnosis is by plain radiographs. On the lateral projection, the femoral head will be lateral and superior to the acetabulum and the femoral shaft will be adducted and internally rotated.

In major trauma, associated acetabulum fractures are often seen. CT scan can help delineate further fractures, especially those to the acetabulum and pelvis.
