Abstract: A fracture fixation system is provided for a fracture of a head portion of a long bone which has subchondral bone defining a convex articular surface. The system includes a plate element positionable on the long bone substantially opposite the head portion of the long bone and on a first side of the fracture, and a post coupled to the plate and into the head portion of the bone and across the fracture. A cross peg is coupled to the post to provide support of the subchondral bone.

Abstract: A jig assembly includes a jig having an elevated first portion having holes or slots to align a drill with screw holes in an intramedullary portion of a fixation device, and a lower second portion having openings in axial alignment with holes on a plate portion of the fixation device. The jig may be locked relative to the fixation device. The jig assembly further includes one or more of sleeves, drill guides and gauges for facilitating the drilling of appropriate holes into bone both beneath and above the fixation device.

Abstract: A fixation system includes a device having a plurality of like threaded peg holes. Two types of pegs are couplable within the peg holes. One type is multidirectional, and the shaft can be oriented at various angles relative to an axis extending through the peg hole. Another peg is directionally-fixed and limited to extension through the peg hole in a single direction; i.e., coaxial with the peg hole axis. The peg holes and both types of pegs are adapted such that either of the pegs can be received within any of the peg holes of the device.

Abstract: A volar plate includes a head portion with two sets of pegs. The first set of the pegs is substantially linearly arranged and the axes of the pegs are preferably oblique relative to each other, and are preferably angled relative to each other in two dimensions. The second set of pegs is provided relatively distal of the first set through a buttress of the head portion of the plate. The second set of pegs is preferably angled relative to the plate such that the pegs are oriented substantially perpendicular to the body of the plate and extend between the pegs of the first set. The first set of pegs provides support for subchondral bone fragments, while the second set of pegs provides support behind the articular bone surface.
