posterior hip dislocation


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.

posterior hip dislocation

A dislocation of the hip onto the dorsum ilii or sciatic notch. Most such dislocations occur when the hip is flexed and adducted and a violent longitudinal force is applied to the femur that forces the femoral head posterior relative to the acetabulum. This dislocation is often seen in automobile accidents.

Symptoms

The condition is characterized by an inward rotation of the thigh, with flexion, inversion, adduction, and shortening; pain and tenderness; and a loss of function and immobility.

Treatment

The patient should first be anesthetized and then laid on his back with the leg flexed on the thigh and the thigh on the abdomen. The thigh is adducted and rotated outward. Circumduction is performed outwardly across the abdomen and then back to the straight position. Traction may be required.
