摘要： A hip implant assembly including a spherical shaped ball and an elongated stem. An annular defining rim separates the ball from the stem and abuts, in a maximum inserting condition, over an exterior reconditioned surface of the femur and upon inserting the stem within an interior passageway formed within the femur. A cup shaped support seats the ball in a universally articulating permitting fashion via a flexible and resilient ligament which extends from the ball and is received within a recess passageway of the cup. The cup also includes a mounting surface with a central projecting portion which is in turn resistively fitted within an undercut defined recess formed in the ilium bone in communication with a base surface of the reconditioned acetabulum socket. A corresponding installation kit assists the preparation of the femur and ilium bones defining the hip joint, as well as the installation of the implant body into the upper conditioned femur end and the cup shaped and outer socket support to a reconditioned acetabulum defined in the ilium bone.

摘要： A method for arthroplasty includes using a self-locking prosthesis that has a member structured to transfer a load produced by the weight of a patient to a bone. An expandable bone-locking portion that is integral to the member includes a shape-memory material and expands to produce a locking force. A portion of the bone is removed to form an aperture in the bone. The bone-locking portion is inserted into the aperture, and a temperature increase causes a change from a contracted state to an expanded state resulting in expansion of the bone-locking portion so as to contact the inner surface. The expanding is sufficient to create a locking force at the junction between the inner surface and the bone-locking portion of the prosthesis and the majority of the locking force is applied at or above the metaphysis. The length/width ration of the prosthesis may be less than or equal to 5. The resulting reconstructed long-bone may have improved primary and long-term stability.
