January’s Specialty of the Month is Hip.
The human hip, like the shoulder, is a ball and socket joint, in which the ball of one bone (the femur, or bone of the upper leg) fits into the socket of another (the pelvic bone). As the most flexible free-moving joint in the body, the normal hip can move backwards and forwards, from side-to-side, and can perform twisting motions. Hip pain may be a symptom of a number of common hip injuries or conditions.
