Presentation transcript:

An AP pelvis x-ray showing a patient with a normal left hip joint and right hip bone-on-bone arthritis. Note the dark, radiolucent “gap” between the ball and the socket on the healthy left hip (white arrow). The dark space between the ball and the socket is full of healthy cartilage. There is an area where there is no cartilage between the ball and socket of the patient’s right hip (yellow arrow). Source: The Hip, Practical Office Orthopedics Citation: Parks E.
