Suture Button

摘要

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.

主权项

1. A bone fixation system comprising:
a suture button having a body that includes a first end surface, a second end surface, a circumferential outer surface, and a first pair of passages formed through the body from the first end surface to the second end surface, the circumferential outer surface including at least one protrusion extending radially therefrom; a bone plate that defines an aperture configured to at least partially receive the suture button and to engage the at least one protrusion;
a suture engaging member including an elongated member having a flexible tube defining a passage therethrough, the elongated member configured to expand and engage a bone; anda suture configured to be looped through the passage in the suture engaging member and to couple the suture engaging member and the suture button.
