Abstract: An orthopaedic prosthesis for implantation in a patient's intramedullary canal includes a prosthesis body and a removable prosthesis stem portion that is connectable to the prosthesis body at the lower end portion of the prosthesis body. The stem is formed of an elongated stem member that is preferably conically shaped, having an inner elongated conical core with proximal and distal end portions. A helical portion extends around the core beginning at a position adjacent to the proximal end and terminating at a position adjacent to the distal end. The stem and body can be connectable using a wedge lock or taper-like connection. The prosthesis stem can provide a socket with internal threads for attaching a removal tool thereto.

Abstract: An in-situ surgical orthopedic milling apparatus includes an instrument frame having upper and lower end portions. A plurality of templates are provided, each forming a respective virtual pattern. A cutting device supported upon the frame cuts bone tissue (e.g., within the intramedullary canal of a patient's bone), by tracking the virtual patterns. A system of vertically stacked templates can be placed in position with respect to the instrument frame to define an operative position. The templates provide a wall portion that constrains movement of the cutting tool beyond a desired surgical cutting area defining an "actual pattern". In this first embodiment, the templates are in the form of stacked templates, each template having its own pattern.

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.

Abstract: A rasp tool including a handle member, a cutter member, and a releasable locking mechanism for selectively coupling the handle and cutter members. The locking mechanism includes a locking post on the cutter member and a corresponding post-receiving bore in the handle member. A spring-biased locking key is disposed within a guide bore that intersects the post-receiving bore such that the locking key extends partially into the post-receiving bore. As the locking post is axially introduced into the post-receiving bore, the locking post contacts the locking key and causes it to retract until the locking post is fully received within the bore, at which point the spring-biased locking key engages a transverse notch in the locking post, thereby preventing axial removal of the post from the bore. The locking key is disengaged from the locking post by a manually-actuable trigger coupled to the locking key.

Abstract: A guide apparatus for preparing the femur of a patient with a rotary mill to receive a femoral hip prosthesis includes a V-shaped guide body having a lower end base portion adapted to extend into the intermedullary canal of the femur and an upper end portion comprised of at least two spaced apart struts so that the overall guide body had a configuration substantially the same as the prosthesis body sought to be implanted in the patient. The lower end of the guide body base provides one or more hemispherical receptacles for holding the hemispherical end portion of a spinning mill bit. A preferably removable transverse guide rail has connection pins at one end portion thereof for forming a connection with the upper end of the guide body at one of the struts, the arm having a curved surface that is adapted to guide the mill bit during preparation of the intermedullary canal of the patient's femur for receiving a hip prosthesis thereafter.

Abstract: 36 The present invention relates to a prosthetic interpositional device/coupler designed to be interposed between the neck and head of a femoral prosthesis. One example of a contemplated environment of use of the inventive interpositional device/coupler is in the situation where the prosthesis has a neck of one material and a head of another material. The inventive interpositional device/coupler may be made with an outer wall having a taper designed to match the taper of the head and with an inner wall having a taper designed to match the taper of the neck. These tapers may differ. Additionally, the inner and outer surfaces may have different surface textures from one another so as to make the respective walls compatible with the surface texture of the material of which the adjacent structure, head or neck, is made. Three embodiments of the inventive interpositional device/coupler are disclosed.

Abstract: A modular broach handle for use with a broach having a tapered configuration beginning at a wider upper end tapering to a smaller lower end. An elongated handle body portion has a longitudinal axis, with one end portion of the handle body defining a connection end portion for attaching a broach thereto at the wide upper end portion of the broach. A slot extends a distance along the handle terminating at one end thereof adjacent a connection end poriton of the handle body. A socket communicating with the slot is formed at the connection end portion of the handle body, the socket having an open end portion receptive of an attachment post on the wide end portion of the broach. A spring loaded slider bar is disposed within the slot for sliding movement therein and with respect to the handle between engaged and disengaged positions, and includes an end portion that extends into the socket when in the engaged position to form a connection with the post.
