Abstract: A calcar trial includes a stem having a proximal end and a distal end, and a body. The body is engaged with the stem near the proximal end of the stem and is slidable with respect to the stem. A locking mechanism inhibits movement of the body with respect to the stem when desired. A collar extends radially outward from the stem to surround a portion of the body. The body and stem are configured so that the diameter of the calcar trial at a point between the collar and the distal end of the stem increases as the body is moved toward the distal end of the stem and decreases as the body is moved away from the distal end of the stem. Additionally, the proximal end of the stem can include opposed notches that are egagable by a forked tool.

Abstract: A modular hip prosthesis can be custom fitted to a particular patient by a surgeon prior to surgical insertion. The prosthesis features a body having a neck portion for carrying a rounded head element, a transitional mid-section of the prosthesis body includes generally rectangular and generally rounded cross-sectional areas, and a stem section has a generally rounded cross-sectional area. The stem is tapered to receive a tubular extension sleeve with a hollowed portion corresponding in shape to the stem portion of the prosthesis. The tubular extension sleeve has an open end portion receptive of the lower tapering stem of the prosthesis body. The stem portion includes an internal bore, and an attachment in the form of an elongated screw is provided for connection to the stem internal bore for securing the extension sleeve and the prosthesis body together, forming a compressive sealed connection therebetween. Pads can be attached to the transitional mid-section of the prosthesis body for increasing the cross-sectional shape of the prosthesis at the transitional mid-section. The pads are loaded continuously to connect to the prosthesis body by the hip joint reaction force. Removable collars can be added to the prosthesis to form a transverse load carrying interface with the upper end of the patient's femur. Frustroconically-shaped extension sleeves can be added to the prosthesis neck for extending the neck length.

Abstract: A set of surgical products which includes an attachment mechanism for modular surgical products. The set includes a plurality of first components and a plurality of second components. One of the first components and one of the second components are to be selected for engagement with each other. The components each include an indexing means including a key on the first components and a corresponding slot on the second components for mating with the key. The orientations of the keys and slots vary, so that only first components having a key orientation that is similar to and aligns with the slot orientation of a second component will properly mate together and so that first components will not properly align and mate with second components having slot orientations that are different from the respective key orientation.

Abstract: An arrangement for preparing an anatomically measured endoprosthesis with a stem to be anchored in the widening end of a hollow bone, in particular a hip joint stem prosthesis to be anchored in the femur, uses radiographs true to scale, a set of a limited number of prosthesis templates and a set of corresponding prosthesis preparation models. In order to obtain greater variability and facilities for individual adaptation, a set of partial templates for that part of the prosthesis stem is provided which is to be anchored in the outer bone section forming the greatest widening. To determine the dimensions of the adjoining prosthesis stem sections, a direction scale and indicator are provided, the partial template and the a direction scale and indicator being mutually connected or connectable in defined directions. A set, corresponding to the partial templates, of trial preparation sections which are connectable to trial prosthesis sections; and for the adjoining prosthesis sections, is provided. Advantageously, the a direction indicator and scale are also each formed by one set of partial templates.

Abstract: The invention relates to a joint prosthesis having an articular member fitted on an implant element housed in the bone cavity so as to slide without turning perpendicularly to the resection surface. The implant element is not provided with any abutting edge to limit its insertion into the bone cavity and the articular member is permanently supported with no twisting moment by the resection surface owing to its sliding possibility. The invention finds an application in hip joint endoprostheses.
