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.
