A volar plate includes a head portion with two sets of pegs. The first set of the pegs is substantially linearly 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.
La plaque palmaire comprend une partie de tête et deux ensembles d'ancrage. Le premier ensemble d'ancrage est sensiblement linéaire et les axes de ces ancrages sont de préférence obliques les uns par rapport aux autres, et forment de préférence un angle bidimensionnel entre eux. Le second ensemble d'ancrage est relativement distal par rapport au premier ensemble grâce à un contrefort de la partie de tête de la plaque. Le second ensemble d'ancrage forme de préférence un angle par rapport à la plaque, de sorte que les ancrages sont orientés de manière sensiblement perpendiculaire par rapport au corps de la plaque et s'étendent entre les ancrages du premier ensemble. Le premier ensemble d'ancrage constitue un support pour des fragments osseux sous-chondraux, tandis que le second ensemble d'ancrages constitue un support entre la surface osseuse articulaire.
