    摘要: A spinal implant tool comprises a steel shaft bifurcated into shaft portions at one end at which a pair of extensions extend from the bifurcated shaft portions. The extensions are flat members which extend from an implant impact element at the end of each of the shaft portions. A spinal bone implant is inserted between the extensions. A shaft portion displacement member has a stud threaded to one of the shaft portions and a knob head for capturing the other shaft portion to the member threaded stud. When the knob is rotated the shaft members are moved apart or closer together. A stop member limits the spread apart distance of the shaft portions.

    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.
