False colour X-ray showing a femoral osteotomy, performed as treatment for osteoarthritis of the hip. The femur (thigh bone) is cut in two just below the joint and the two ends are realigned. The operation allows weight to be carried through a different, largely undamaged, portion of the articular cartilage, thus reducing pain and disability in the joint.
