摘要： A proximally hollow prosthesis is provided having a cap element and a stem; the prosthesis, in one embodiment, has a cap element suitable to be adapted to a ball and hip socket and has a stem suitable to be implanted in a reamed femoral medullary canal. The stem of the prosthesis has a proximal region and a distal region and is mateable with the cap element of the prosthesis. The proximal region of the stem is open to define a cavity which extends longitudinally a predetermined distance through the proximal region of the stem but not into an isthmus region of the stem, which is located distal to the proximal region of the stem. The distal region of the stem is located distal to the isthmus region of the stem and is made of solid metal or alloys thereof. In another embodiment of the invention, the distal region of the stem is furcated, being at least bifurcated so as to define a plurality of tangs.

摘要： A method and tool for inserting a prosthetic stem component in an aligned position into a prepared bone cavity. The bone is prepared by removing bone material from the bone canal and preferably also machining an entry opening of a predetermined shape and desired orientation in the bone, or marking the plane of the joint on the bone end. The tool includes an upper component that engages the top of the prosthesis stem to fix its rotational alignment, and an arm that extends to the opening in the bone and is aligned at its distal end. The upper component rides along the arm, and orients the stem with respect to the bone as the stem is inserted. The tool may include a lower element that engages the machined or marked bone and holds the arm to orient the head of the prosthesis. Optionally, the lower element may guide the distal stem. Alternatively, the guide may include an arm that simply points to, contacts or fastens at the bone end, orienting the prosthesis insertion without sighting errors. In a pointer or pin assembly which extends to an alignment point on the proximal femur, the upper portion may clamp to the femoral component head or neck, and may include a sliding bushing, that allows the guide to remain rigidly coupled as the stem is progressively advanced in the femoral canal. Articulation may be provided by a pivot mounting of the arms and bushing, and the bushing may swivel as it rides along a post, rail or pin, the lower end of which remains pointed to, or driven into, an alignment mark scribed at the medial periphery of the cut surface of the proximal femur. Alternatively, a lower alignment body may fit against a machined bone surface to fix the orientation of a linking arm in one plane, with a sliding coupling to the upper part of the prosthesis to maintain that orientation as the stem is driven down into contact with the prepared bone surface.

摘要： A modular acetabular reinforcement system includes a substantially cup-shaped reinforcement body having a peripheral flange portion. One or more fixation wings, of various sizes and shapes, are selectively and separately attachable to the flange portion of the reinforcement body. The system is mountable within the acetabulum of a patient to reinforce the acetabulum and to serve as a platform for other prosthesis components such as an acetabular shell.

摘要： A femoral head trial adaptor for converting a shell trial to a head trial includes a barrel member having an outer surface and an inner surface defining a cavity for receiving a femoral neck trial. A circumferential flange portion is located on the outer surface of the barrel member. A resilient connecting member disposed on the circumferential flange has a nominal first diameter compressible to a smaller second diameter in response to a force and returnable to the first diameter in the absence of the force for securing the trial adaptor to a shell trial. The flange may be located at a predetermined position along the outer surface of the barrel member so as to simulate a neck trial of a given length.

摘要： A prosthetic stem inserter device includes an elongate rod member having a handle portion and an elongate rod member having a distal portion which has a plurality of surface features formed thereon which define a series of predetermined stem insertion depths. The device further includes a depth guide member having a proximal portion removably and replaceably engageable with the surface features on the elongate rod member. A distal, bone engaging portion of the depth guide member protrudes beyond a distal end of the elongate rod member. The depth guide member includes a mounting plate having a substantially hemispherical opening slot therein and a pair of distally extending prong elements. Each prong element has a first, longitudinally extending portion and a second portion that is angled with respect to the first portion. The second portion is adapted for contacting a plane of calcar bone in a prepared femoral cavity when a femoral stem is inserted into the cavity.
