Femoral fixation

摘要

Various methods and devices are provided for a graft fixation device for fixing a graft member within a bone tunnel. In one embodiment, a graft fixation device is provided having a radially expandable sheath adapted to be disposed within a bone tunnel, and a sheath expander adapted to be received within the radially expandable sheath to expand the sheath and thereby anchor a graft between the sheath and the bone tunnel. In an exemplary embodiment, the graft fixation device is particularly useful to affix a graft within a femoral tunnel.

主权项

1. A method for fixing a ligament graft in a bone tunnel comprising the steps of:
positioning a leading end of a graft within a femoral tunnel, the graft having a trailing end that extends through a tibial tunnel; inserting a flexible sheath into the femoral tunnel, the flexible sheath having first, second, and third sidewalls that are attached to one another at first, second, and third attachment points and that define sides of an inner lumen extending through the flexible sheath, and the flexible sheath having a substantially triangular cross-sectional shape such that flexible sheath positions the graft on a posterior side of the femoral tunnel; and inserting an expansion plug into the flexible sheath to expand the flexible sheath and thereby fix the leading end of the graft within the femoral tunnel and cause each of the first, second, and third attachments points to break.
