International ClassA61B 017/00AbstractA bone anchor (10) for securing a suture to a bone (38). The bone anchor (10) has a tip (16) at its distal end (18) and at least one resilient wall (27) extending to a trailing end (20) of the body (12) of the anchor. The wall (27) has a ridge (14), or barb, formed on an outer surface. The ridge (14) defines an edge (34) that digs into a hole (36) in the bone (38) in which it is positioned. A strand of suturing thread (22) extends through a suture receiving opening (24) in the tip (16) of the anchor. The method of the present invention employs the suture anchor (10) and includes the steps of forming a hole (36) in a bone (38) and inserting the suture anchor (10) to a desired depth in the hole (36) in the bone (38) using an inserter device (100). Suturing thread ( 22) extends from the suture receiving opening (24) in the tip and along the length of the walls (27,28) out of the hole (36) in the bone (38). An anchor spreader (130) is used to firmly seat the anchor (10) in the hole (36). The suture (22) is pulled at the same time to help seat the barbs 14 on the anchor (10) into the bone (38).Other References
