Method and apparatus for attaching soft tissue to bone

摘要

The present teachings provide for a graft fixation assembly including a base member, a compression member, and a fastener. The base member includes a bone engaging surface and a first graft engaging surface opposite to the bone engaging surface. A plurality of first fixation members extend from the bone engaging surface and are configured to be impacted into bone. The compression member includes a second graft engaging surface and an outer surface opposite to the second graft engaging surface. The fastener is configured to secure the compression member relative to the base member such that a graft between the base member and the compression member is compressed therebetween and secured to the graft fixation assembly.

1. A graft fixation system comprising:
a base member including a bone engaging surface and a first graft engaging surface opposite to the bone engaging surface; a plurality of first fixation members extending from the bone engaging surface and configured to be impacted into bone; a compression member including a second graft engaging surface and an outer surface opposite to the second graft engaging surface, the compression member is separate and distinct from the base member and configured to be fastened thereto; and a fastener configured to secure the compression member relative to the base member such that a graft between the base member and the compression member is compressed therebetween and secured to the graft fixation system; wherein the bone engaging surface is convex and the first graft engaging surface is concave to provide the base member with a curved shape in cross-section; wherein the second graft engaging surface is convex and the outer surface is concave to provide the compression member with a curved shape in cross-section; and wherein the first graft engaging surface is complementary to the second graft engaging surface.
