Surgical bone screw
First Claim
1. A surgical interference screw for use in attaching bone to bone and soft tissue to bone, the interference screw comprising:
- an elongated body having a proximal head portion and a distal insertion end and being constructed from bone, the elongated body defining a longitudinally extending bore which extends from the proximal head portion towards the distal insertion end, the longitudinally extending bore including engaging structure formed along at least a portion of the longitudinally extending bore, the engaging structure being configured and dimensioned to non-rotatably engage an insertion tool for inserting the interference screw into bone, and the proximal head portion being configured to simultaneously non-rotatably engage the iron tool to evenly distribute forces required to insert the interference screw throughout the interference screw during insertion of the interference screw into bone.

Abstract
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.
