  • Publication number: 20110144759
    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.

  • Publication number: 20100256640
    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.
