Rectus femoris muscle: an obstacle in reduction of acute traumatic anterior dislocation of hip in an adult.
A case of traumatic anterior dislocation of the hip that could not be reduced closed is described. On exploring the hip, the rectus femoris muscle was found to be buttonholed by the head of the femur, resulting in failure of closed reduction. Release of the muscle from its origin resulted in easy reduction.
