A low profile dorsal plate for internal fixation of a radius fracture can comprise a single longitudinal portion having a distal end, and a transverse portion fixed across the distal end at an angle of about 15&#xb0; to about 30&#xb0; from perpendicular with respect to the longitudinal portion. The transverse portion can also have a z-axis curvature, or can be flexible to form a z-axis curvature, where the z-axis curvature corresponds to a dorsal contour of a distal radius. Also included is a first plurality of screw holes aligned within the longitudinal portion and a second plurality of screw holes aligned within the transverse portion.

Low profile dorsal plate

A method for implanting a prosthesis system for replacement of a head portion of a proximal radius includes determining a distance between a proximal radius and a humerus. The method also includes selecting one of a first head component or a second head component based on the determination. The first and second head components have unique heights. The method further includes connecting the selected first or second head component to an articulation component and connecting a stem component to the selected first or second head component.

Modular radial head prosthesis

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.

Modular prosthesis and use thereof for replacing a radial head

A prosthesis system for replacement of a head portion of a proximal radius can include an articulation component having a first connection portion. A first head component can have a second connection portion that connects to the first connection portion. A second head component can have a third connection portion that connects to the first connection portion. The second head component can have a distinct dimension from the first head component. A stem component can include a fourth connection portion that connects with either of the first or second head components. The stem component can have a stem anchoring portion that connects to the radius.

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.

Method and apparatus for adjusting height and angle for a radial head

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.

A modular prostheses system for replacement of the radial head portion of the radius bone, and methods for its use are disclosed. The system comprises a stem component comprising a anchoring portion and a mounting portion, and a head component having an open channel wherein the open channel is configured to connect to the mounting portion along an assembly axis that is transverse to a longitudinal axis of the stem component.
