  • Method of implanting a bone fixation assembly
    Patent number: 9433407
    Abstract: A bone fixation assembly can include a suture button, a bone plate, and a suture assembly. The suture button can include a body that has a first end surface, a second end surface, and a circumferential outer surface. A first pair of passages can be formed through the body from the first end surface to the second end surface. The circumferential outer surface can include at least one protrusion or retaining rib extending radially therefrom. The bone plate defines an aperture. The suture button is configured to be at least partially received into the aperture in an assembled position such that the retaining rib engages the bone plate and inhibits withdrawal of the suture button from the aperture in the assembled position. The suture assembly includes a suture engaging member and a suture configured to couple the suture engaging member in the suture button.
