  • Patent number: 9504581
    Abstract: A modular humeral head resurfacing implant including a head, an anchoring stem, and a modular extended articulation flange. The head includes an exterior hemispherical articulating surface defining a terminating rim, an interior concave surface opposite to the exterior articulating surface, and a first coupling mechanism proximate to the terminating rim. The anchoring stem is coupled to the interior concave surface and extends along a stem axis that extends through an axial center of the head. The articulation flange includes a second coupling mechanism configured to cooperate with the first coupling mechanism to fasten the articulation flange to the head and an outer articulating surface that is curved along substantially its entire length and is substantially flush with the exterior hemispherical articulating surface when the articulation flange is fastened to the head.

  • Patent number: 9333084
    Abstract: A tool provides for coupling a first prosthetic to a second prosthetic. The tool can include a first arm having a first concave bearing surface configured to apply a force in a first direction. The tool can also include a second arm having a hook shaped member. The hook shaped member can have a second concave bearing surface configured to apply a force in a second direction opposite the first direction. The first arm and the second arm can be generally parallel, and the first arm can be translatable with respect to the second arm. The tool can include a translation force mechanism, which can apply force to the first arm and the second arm so as to cause generally parallel translation of the first arm and second arm.

  • Patent number: 8585768
    Abstract: A method and apparatus for replacing a selected portion of the anatomy is described. In particular, a prosthesis can be provided to replace a portion of an articulating joint, such as an elbow. The apparatus can be modular for various reasons and each of the modular portions can include a different dimension to achieve a selected result. For example, the prosthesis can achieve a different size condylar replacement, a selected offset, a selected articulation, or combinations thereof.

  • Patent number: 8425614
    Abstract: A glenoid component used for shoulder arthroplasty is adapted to be implanted into a scapula and engaged by a head of a humeral component. The glenoid component includes a body having a first articulating surface and a second medial surface opposite to the first articulating surface. The first articulating surface is adapted to engage with a humeral head. A plurality of removable fixed pegs each have a first end adapted to engage a cavity formed in the scapula and a second end extending from the medial surface. A central peg fixation mechanism is provided that is configured to couple an optional central fixation peg to the medial surface.

  • Patent number: 8425615
    Abstract: A modular prosthesis system for replacement of a head portion of a radius. The prosthesis system includes a head component having a first connection portion that connects to a second connection portion and a collar component having the second connection portion and a third connection portion. The system also includes a stem component including a fourth connection portion that connects with the third connection portion, the stem component having a stem anchoring portion that connects to the radius. The collar component provides the modular geometry to the prosthesis without having to have an increased number of head components and stem components with variable lengths and angles.

  • Patent number: 8366781
    Abstract: A modular prosthesis system for replacement of a head portion of a proximal radius includes a monolithic stem component, a head component, and a locking mechanism formed by the stem and head components. The stem component defines a stem anchoring portion having a longitudinal axis and configured to couple to the proximal radius, and a dovetail-shaped first mounting portion on a first end face that extends in a first direction transverse to the longitudinal axis. The head component has a dovetail-shaped second mounting portion on a second end face opposite the first end face slidably engaged with the first mounting portion along the first direction. One of the first and second mounting portions intersects the longitudinal axis. The locking mechanism is formed at an interface between the stem and head components and is engaged through relative translational movement between the stem and head components. A related method is provided.

  • Patent number: 8012155
    Abstract: A method and apparatus configured to strengthen and support a portion of a bone, such as the femoral head of the proximal femur, for example. The apparatus may include a housing or base member and a movable support member connected to the housing and configured to move between a first, undeployed position in which the support member is disposed proximate the housing or base such that the apparatus may be inserted into bone, and a second, deployed position in which the support member extends away from the housing or base for supporting the femoral head. The support member may be a rod, one or more wires, a leaf spring, a bladder, or an expandable mesh material, for example.
