An improved modular rotational device includes a first and second threaded coupler for affixation along the stem of an endoprosthetic device, for example, a humeral prosthesis or a femoral prosthesis. The rotational device axis of rotation is coaxial with the stem, and its axis of rotation is located in close proximity to the intramedullary stem of the prosthesis or in close proximity to the distal articulation of the prosthesis. A housing has a proximal and distal end with an axial bore therethrough for receiving an elongated stem of the device. A lobe ring may be utilized to limit the axis of rotation of the device. Additional endoprosthetic devices may be attached to male or female threaded couplers, or to Morse tapers. A plurality of suture attachments facilitates attachment of soft tissue thereto.

A tool for use with an orthopaedic implant includes: a tubular assembly including a tubular passage having a first end and a second end, the first end including a means for attachment to an implant body; a plug; and a plunger coupled to the plug. The tubular passage is configured to receive, via the second end, a material agent and the plunger coupled to the plug. The plunger is configured to slide through the tubular passage for expelling the material agent from the tubular passage into a load bearing member via the at least one first opening. The plunger is configured to rotate within the tubular passage for coupling the plug with the first opening to seal the first opening against expulsion of the material agent from the load bearing member via the first opening.

An orthopaedic implant includes an implant body comprising a biocompatible material and configured to be implanted at an anatomical location, the implant body defining a surface; and a porous material at least one of attached to and integral with the surface of the implant body, the porous material having a plurality of grooves formed therein.

An orthopaedic implant includes a patella component having a metal base with a polymer bearing molded thereto. A method for making a patella component is also disclosed.

This orthopedic implant includes a polymer substrate with an outer surface intended to be secured to a bone tissue. The outer surface is covered with metal particles including titanium. The particles include large primary particles and small secondary particles. The primary particles and the secondary particles are evenly distributed over the outer surface.

A three-dimensional scaffold for a medical implant includes a plurality of layers bonded to each other. Each layer has a top surface and a bottom surface and a plurality of pores extending from the top surface to the bottom surface. Each layer has a first pore pattern of the pores at the top surface and a different, second pore pattern at the bottom surface. Adjacent surfaces of at least three adjacent layers have a substantially identical pore pattern aligning to interconnect the pores of the at least three adjacent layers to form a continuous porosity through the at least three adjacent said layers.

A surgical implant with recesses adapted to capture fixation medium that extravasates during implantation. The implant includes an elongated stem having a distal tip configured for insertion into an implant receiving area of a patient. A collar having recesses for capturing extravasating fixation medium is attached on the stem. The collar can be fixed to the stem by a separable collar-engagement feature or the collar can be fixed to the stem via structures on the stem.

Embodiments of the invention described herein thus provide systems and methods for providing improved surgical implants. Embodiments of the implants may include a thin porous sheet formed on a mandrel. The porous sheet that is formed has an interconnected pore structure that may be compressed by a heat compression mold without losing porosity. Additional membrane materials or other layer materials may be applied to one of the face surfaces of the porous sheet or to one of the edges of the porous sheet. For example, a solid membrane surface may be compressed, bonded, welded, or secured a surface face or an edge of the porous sheet. The solid membrane may be compressed or laminated to the upper surface, lower surface, or both. The solid membrane may be welded to at least one edge of the porous sheet (by, for example, being butt welded, thermally bonded, or heat compressed to the at least one edge).

Graft for a bone defect, in particular a tibial head graft for a knee-joint endoprosthesis. It comprises a sleeve-like inner body (2) for implantation at one end of a long bone (99). An outer face of the inner body (2) is designed as a bone contact face (20) for bearing on the surrounding bone margin (97). According to the invention, an outer shell piece (3) is provided which, as a bone replacement piece, is doubled onto the outside of the inner body (2) for filling a defect at the cortical bone margin (97) and is not dimensioned peripherally, such that, in the circumferential direction, it covers only a part of the outer circumference of the inner body (2). The doubled outer shell piece (3) forms a filler piece for a bone defect (bone window 96) at the bone end. Closure of the bone window (96) is achieved, and unwanted contact between the graft and surrounding soft-tissue parts is avoided. Moreover, the graft is thus also supported in the region of the bone window (96). Parts of the bone margin (97) that are still present can thus remain intact, allowing the greatest possible preservation of naturally present bone substance.

A bone fusion method, apparatus and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable plates having a central rib. The bone fusion device includes one or more support channels configured to receive an insertion instrument that is then secured to the bone fusion device via a coupling mechanism. As a result, the coupled device is able to be securely positioned between vertebrae using the insertion instrument with minimal risk of slippage.
