Abstract: An improved body element for use in a modular prosthetic stem component of the sort comprising a body element and at least one other element, wherein the body element and the at least one other element are joined together by at least one modular connection, wherein the improved body element comprises an anterior wall and a posterior wall, at least one of the anterior wall and the posterior wall converging toward the other on the medial side of the body element and diverging away from the other on the lateral side of the body element, whereby the body element approximates a general wedge shape.

Abstract: A prosthetic femoral stem component comprising a body element, a neck element and a stem element, with the body element, neck element and stem element being secured to one another with a modular connection, wherein the modular connection comprises a taper junction and an engaged-fit junction.

Abstract: A bone milling instrument is disclosed for creating a shaped cavity from an initial cavity in a bone, the bone milling instrument comprising a reference frame, a centering member at the distal end of the reference frame, a registration surface for engaging a portion of the initial cavity, and an attachment site provided proximally of the registration surface, a guidance support member, an attachment mechanism at the first end of the guidance support member, and a constrained pathway extending between the ends of the guidance support member; a shuttle having a first connection element configured for positionably attaching the shuttle to the guidance support member, and a second connection element configured to provide a rotational coupler; and a cutting device having a cutting portion configured at a distal end thereof, and an attachment portion provided at a proximal end.

Abstract: This invention provides apparatus and a method for assembling a modular hip implant where the desired orientation of the neck component is uniquely determined during the trialing phase of the operation, and that same desired orientation is accurately reproduced during the implantation phase of the actual hip implant device.

Abstract: This invention provides for a tool that produces, and directly and accurately measures, an axial force used to assemble two members of a modular implant, specifically, a modular hip implant.

Abstract: This invention provides for a system of temporary or “trial” implants which are used to establish the optimal location of the femoral head relative to the body of the hip stem implant. Using a series of interchangeable modular femoral neck components that mate with a series of interchangeable modular femoral body components, the location of the femoral head can be independently adjusted with respect to horizontal offset, vertical offset and anteversion angle relative to the body.

Abstract: A prosthetic femoral stem component comprising a body element, a neck element and a stem element, with the body element, neck element and stem element being secured to one another with a modular connection, wherein the modular connection comprises a taper junction and an engaged-fit junction.

Abstract: An orthopedic component comprising a first element and a second element, with the first element and the second element being secured to one another with a modular connection, wherein the modular connection comprises a taper junction and an engaged-fit junction.

Abstract: Systems and methods are described for implants with composite coatings to promote tissue in-growth and/or on-growth. An implant includes: a substrate; a structured surface formed on at least a portion of the substrate; and a biocompatible coating deposited on at least a fraction of the structured surface. The systems and methods provide advantages in that the implant has good biocompatibility while the biocompatible coating has good strength.
