摘要
A fixation system includes a device having a nail portion and a plate portion, preferably horizontally and vertically offset relative to the nail portion by a neck portion. The nail portion includes threaded screw holes, and the plate portion includes longitudinally displaced peg holes, each of which is adapted to orient a peg in a different orientation from the others. The system also includes unicortical screws having a reasonably large head adapted to seat against the outer surface of the bone and a threaded shaft adapted to engage in the screw holes, and pegs adapted to engage in the peg holes. Bone is clamped between the nail portion and the head of the unicortical screws. The pegs provide stabilization and support for subchondral fragments. Moreover, as the pegs preferably enter the subchondral fragments from a plurality of directions, additional fixation of the device into the bone is provided.
