Dislocations of the hip

Description: Posterior Hip Dislocations
Posterior hip dislocations are the most common. The usual cause is a motor vehicle accident with the passenger's knee hitting the dashboard and forcing the femoral head out of the acetabulum posteriorly. The limb is shortened, and the hip flexed, the foot is in internal rotation.
