    摘要: An interference screw suitable for surgical use is provided. The interference screw is constructed from bone and includes an elongated body having an outer threaded surface, a tapered insertion end and a central throughbore. Insertion tool engaging structure is formed along the walls defining the throughbore. The insertion tool engaging structure extends from the proximal end of the elongated body over a substantial portion of the length of the elongated body. The insertion tool engaging structure functions to distribute the forces required to insert the interference screw throughout the body of the interference screw to prevent fracturing of the interference screw during insertion into bone.
