posterior dislocation of the hip
Last reviewed 01/2018
About 80% of hip dislocations are posterior.
This type of injury will often occur in a road accident. In this situation the patient may have been seated in a car and been thrown forward hitting their knee against the dashboard and forcing the femoral head upwards and backwards dislocating the hip joint posteriorly. This type of injury may cause a concomitant fracture of the acetabulum and so be a fracture-dislocation of the hip joint.
