GRAFT ANCHOR

摘要

A graft anchor (10) includes an anchor member (12) for placement in bone tissue (4). The anchor member (12) defines an opening (22). An inner member (16) is inserted securable into the anchor member (12) opening (22). A fastener (14) is configured such that insertion and securing of the inner member (16) into the anchor member (12) opening (22) results in a holding force being applied to the graft (2). The anchor member (12) is of limited length to maintain its distal end (30) within the bone (4). The anchor member (12) includes a distal drive opening (83) for receiving a drive tool (80) and the inner member (16) includes a proximal drive opening (34) for receiving the drive tool (80). The fastener (14) includes channels (150, 152) for containing the graft (2), a fastener body (56) with protrusions (40) extending from the fastener body (56) for penetrating bone tissue (4), and a reinforcing member (54) contained within the fastener body (56).
