APPARATUS AND METHOD FOR SUTURE ATTACHMENT

摘要

A cannulated bone screw (11) is illustrated that retains a knotted suture an d which is anchored to bone. The cannulated bone screw comprises a biocompatible body (13) having a proximal end (15) an d a distal end (17), and the body includes exterior screw threads (19) for inserting and retaining the body into the bone. The body is cylindrical and has a passageway (23) that ex- tends axially therethrough. The passageway includes a central portion (24), a distal portion (25) and a proximal portion. The cen- tral portion has a diameter less than the distal portion and is sized to receive a suture thread therethrough. The distal portion is sized to recived a suture thread knot (27). The suture thread knot received within the distal portion is retained by the central por- tion, which is sufficiently small to prevent the knot from being drawn therethrough. The proximal portion includes a hexagonal cavity (31) for cooperating with an external drive tool for rotating the bod y and thereby driving the body into the bone.
