Abstract:
1. A method for treating a hip joint of a leg, wherein the hip joint comprises a concave acetabular cup surface rotatably supporting a convex femoral head surface, the concave acetabular CUP surface of the hip joint comprises a fossa, said method comprising the steps of: providing an elongate member having a proximal end, a distal end and an ex positioning the expandable member in the joint between the concave acetabular cup surface and the convex femoral head surface, wherein the step of positioning the expandable member in the joint comprises positioning at least a portion of the expandable member in the acetabular fossa; expanding the expandable member, while the expandable member remaining in the acetabular fossa during the expansion of the expandable member, so as to displace the convex femoral head surface from the concave acetabular cup surface; while the displaced convex femoral head surface is supported on the expanded expandable member, manipulating the displaced convex femoral head surface vis-a-vis the concave acetabular cup surface, wherein such manipulation comprises rotating the displaced convex femoral head surface about the concave acetabular cup surface, and further wherein such manipulation comprises at least one from the group consisting of flexion, extension, lateral rotation, medial rotation, abduction and adduction of the leg; and while the displaced and manipulated convex femoral head surface is supported on the expanded expandable member, performing a therapeutic procedure on the joint.
