METHOD AND IMPLANT FOR STABILIZING SEPARATED BONE PORTIONS RELATIVE TO EACH OTHER

摘要

For stabilizing two separated bone portions relative to each other an implant is used, which comprises a peg and bridge assembly (1) and a securing element (4). The peg and bridge assembly comprises at least two peg portions (2) and a bridge portion (3), wherein the bridge portion (3) is arranged between the peg portions (2) and wherein in the peg and bridge assembly (1) peg and bridge portions are rigidly connected. For stabilizing the bone portions, the peg and bridge assembly (1) is positioned relative to the bone portions such that one peg portion extends into the bone tissue of each one of the bone portions and the bridge portion (3) extends across the gap separating the bone portions. For retaining the peg and bridge assembly (1) in its position, the securing element (4) is anchored in the bone tissue of one of the bone portions, its proximal end extending through an opening (5) in an assembly portion extending parallel to a bone surface or across a notch in a proximal edge of an assembly portion. Compared with known plate and screw systems used for the same purpose the described implant allows more design freedom because the peg portions are substantially freed from the function of retaining the implant in its position.
