A femoral stem hip implant for insertion into a surgically created aperture in a femur includes a monolithic femoral stem made of shape memory material. The stem is configured to be inserted into the aperture, has a proximal portion and a longitudinal axis. The shape memory material within the proximal portion has a cross-section perpendicular to the longitudinal axis. At least a portion of the shape memory material within the proximal portion is in a compressed state by application of a plurality of compressive forces at a temperature below an austenitic finish temperature of the shape memory material so that the cross-section expands through shape memory effect via the formation of austenite in response to a temperature increase after insertion into the aperture thereby causing a locking-force to be exerted against an inner surface of the aperture, the locking force being sufficient to stabilize the implant in the aperture.

A method for manufacturing an object having a potential {x} which is generated in response to a field {f} applied thereto is provided. The method includes the step of designing a geometric model of the object. A computerized mathematical model of the object is generated by discretizing the geometric model of the object into a plurality of finite elements and defining nodes at boundaries of the elements, wherein values of the field {f} and potential {x} are specified at the nodes. A material property matrix [k] is then calculated based on the relationship {f}=[k] {x}. Material property coefficients are then extracted from the material property matrix [k] for each finite element in the computerized mathematical model and the extracted material property coefficients are compared to material property coefficients for known materials to match the extracted material property coefficients to the material property coefficients for known materials. Manufacturing parameters corresponding to the matched material property coefficients are then determined. The object is then manufactured in accordance with the determined manufacturing parameters.

An orthopedic implant in the form of a hip joint endoprosthesis consists of a head, which is set onto an anchoring shaft, which itself is insertable into a bone and anchorable therein. The head comprises an inner blind-hole-type recess, and the anchoring shaft is provided with a tenon for inserting into this recess. A sleeve provided with an approximately central through-bore is soldered into the recess of the head, via which sleeve the head is setable or mountable on the tenon. The head consists of a ceramic based on zirconium dioxide, aluminum oxide or a mixed ceramic, while the sleeve consists of a high strength titanium material. The connection between the head and the sleeve is produced by a silicate ceramic solder that solidifies or hardens in a ceramic firing, as well as by a subsequently applied glass solder, of which the excess can exit via the through-bore into a hollow space existing between the sleeve and the tenon. Both the recess of the head as well as the metallic sleeve are embodied approximately cylinder-shaped.

Принадлежит: Biomet Manufacturing LLC

Disclosed are methods and systems to determine proper seating engagement of a first orthopedic component with a second orthopedic component to ensure stability of the assembled implant. In an example, the first orthopedic component is a head for a shoulder or hip prosthesis and the second orthopedic component is a stem for the shoulder or hip prosthesis, and the head and stem can be attached via a taper junction. The methods and systems can include contacting the first or second orthopedic component to excite the first or second orthopedic component and generate a measurable response, and evaluating the measured response to determine whether the first orthopedic component is properly seated with the second orthopedic component. In an example, a tooling component can physically contact the first or second orthopedic component and generate a vibrational response. The same tooling component or a second tooling component can include one or more sensors to measure the vibrational response and provide an output to the user.

Surgical tools which are used to separate from one another a femoral cup and an acetabular ball in an implanted hip replacement prosthesis. At its distal end, elements of the surgical tool engage the femoral cup and the acetabular cup. When proximal handles of the tool are squeezed toward one another, the engagement elements move away from one another. Thus, a surgeon is able to separate the femoral cup and the accetabular ball from one another without pulling the acetabular cup away from the acetabulum or the femoral cup and/or femoral implant away from the femur, thereby accomplishing the separation without disrupting any bone ingrowth.
