Abstract: A prosthesis for reconstructing a multibone joint such as a wrist. A patient's scaphoid is removed to create a void. The scaphoid has a plurality of adjacent bones, each of the adjacent bones comprising a surface generally facing the void. The surface of at least two of the adjacent bones is prepared by affixing a magnetic element thereto and a magnetic scaphoid implant is inserted into the void. A magnetic relationship exists between the magnetic elements and the magnetic scaphoid implant.

Abstract: A carpometacarpal prosthesis system generally includes a trapezial implant for replacing an excised trapezium within a human hand and a component stem implant for replacing a partially excised first metacarpal. The component stem implant is adapted to be press fit within the medullary cavity of the partially excised first metacarpal bone of the human hand; the component stem when so implanted is adapted to effect universal movement of the first metacarpal bone relative to the trapezial implant thereby providing a restructured thumb metacarpal joint that restores substantially normal thumb function in terms of strength and flexibility.

Abstract: An implant couples a first bone of a hand to a second bone of the hand. The implant includes a body that defines a median plane. The body also defines a first joint surface having a first central region that articulates with the first bone. The body further defines a second joint surface having a second central region that articulates with the second bone, and the second central region is disposed on an opposite side of the median plane of the body relative to the first central region. The first and second central regions correspond to profiles of first and second axial segments, respectively, the first and second axial segments are each one of a cylinder, a cone and a torus and are centered on first and second axes, respectively, and the first and second axes, as projected on the median plane, are substantially perpendicular to each other.

Abstract: A modular resurfacing implant for a radioscaphoid joint of a wrist includes a stem and an articular component coupled to the stem. The stem includes a threaded body for implantation into a distal radius and a connection member positioned at a second end of the stem. The articular component includes a body member configured to resurface a scaphoid fossa of the distal radius. The body member includes a concave top surface matching a curvature of the scaphoid fossa and a bottom surface having a post extending therefrom that is configured to mate with the connection member of the stem. The articular component is configured to resurface the scaphoid fossa while leaving a lunate fossa of the distal radius intact.

Abstract: Surgical implants for neighboring bones are disclosed herein. Preferred implants are configured to be implanted into the scaphoid and lunate. Preferred implants include a first plate configured to be implanted into the scaphoid and a second plate configured to be implanted into the lunate wherein said first and second plates are couple together by a rotatable rod.

Abstract: A wrist prosthesis system to replace at least a portion of a bone of a wrist of a patient. The system includes a carpal implant to replace at least a portion of a carpal bone of a carpal complex of the patient. The carpal implant includes a base and an augment that replaces at least a portion of the carpal bone. The augment is removably coupled to the base.

Abstract: Solid-state deformation processing of crosslinked high molecular weight polymers such as UHMWPE, for example by extrusion below the melt transition, produces materials with a combination of high tensile strength and high oxidative stability. The materials are especially suitable for use as bearing components in artificial hip and other implants. Treated bulk materials are anisotropic, with enhanced strength oriented along the axial direction. The material is oxidatively stable even after four weeks of accelerated aging in a pressure vessel containing five atmospheres of oxygen (ASTM F2003). Because of its oxidative stability, the deformation processed material is a suitable candidate for air-permeable packaging and gas sterilization, which has thus far been reserved for remelted crosslinked UHMWPE.

Abstract: System, including methods, apparatus, and kits, for connecting bones and/or bone portions using a bone connector with a pivotable ball and socket joint.

Abstract: An implant system and apparatus configured to permit motion of the wrist in at least one physiological direction, as well as in a dart thrower's motion, and constrain motion of the wrist in at least one non-physiological direction are provided. The implant according to one embodiment includes a distal component and proximal component. Each of the distal and proximal components includes a primary articulating portion and a secondary articulating portion. Primary and secondary articulating portions include at least one component having either a substantially convex or a substantially concave shape. The secondary articulating portion is configured to be radially and volarly disposed in relation to the primary articulating portion.

Abstract: A distal component for a wrist prosthesis that utilizes fixation within the carpus complex, incorporates features that improve the probability of intercarpal fusion and allows modularity of articulating components. In one form, the subject invention includes an ovoid fixation plate having three holes and a boss. The three holes allow attachment of stems and/or screws distally for fixation in the carpus. The boss projects proximally from the plate, and serves as an attachment point for the articulating head. Modularity of the fixation and articulating components allow a surgeon many options for optimizing fixation distally, and articulation proximally. The proximal head of the distal component is designed to articulate with existing radial components. Since the proximal head of the distal component is modular, however, the head can be redesigned to accommodate later design changes in proximal components.

Abstract: A method is provided for implanting a joint prosthesis for a damaged joint, wherein the steps include removing the damaged joint and initially anchoring two stem members into adjacent bones and inserting a temporary occupier at the joint location between the two stem members. The occupier is configured to allow only limited movement of the bones having the stem members. After the area around the occupier has healed, the occupier is removed and a specially configured ball and socket is installed as the joint to allow for incremental adjustments of the ball and socket relative to the two stem members during the installation procedure to simulate the natural bending motion of the joint once healed.
