A system and method for internal pelvic fixation. Guide wires can be inserted through guides and opposing sides of a pelvic bone, and can indicate a depth for driving bone screws into the pelvic bone. Offset rod tools positioned about each guide can assist in determining an offset distance between an implant rod and the pelvic bone. A template rod may be coupled to the offset rod tools and used to select a length for the implant rod. Clamps can be coupled to the bone screws, the clamps having multiple axes of rotation, the angular positions of the clamps being secured by the tightening of a single nut of each clamp. Joysticks used to tighten the nuts can be coupled to a reduction holder mechanism that can decrease at least an axial distance between the clamps, and thus pelvic bones, before locking of the clamps via tightening of the nuts.

Internal pelvic fixator

A radial head prosthesis for implantation in a distal radius. The implant includes a head portion and a stem portion. The stem portion has a cylindrical shaft and tapered tip. The head portion includes a recess for engagement with the stem portion. The head portion includes a first bearing surface for articulation with a humerus, and a second bearing surface for articulation with an ulna. The second bearing surface includes at least one concave and one convex portion immediately adjacent one another.

Radial head implant

A radial head trial device for replacement of a proximal radial head includes a stem component having a center longitudinal axis extending between a proximal end and a distal end, a head component axially and removably attachable to the stem component, wherein the head component is interchangeable with a selection of other head components each axially and removably attachable to the stem component, an anti-rotation feature, and a recess, wherein the anti-rotation feature is structured to be received in the recess to prohibit rotation of the head component relative to the stem component.

Radial head trials

Fusion devices include blade anchors. The blade anchors may slidingly penetrate a bone or bone fragment, and may induce compression of one bone to another or one fragment to another. The fusion devices may also include a body to which the blade anchors connect.
