    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.

    摘要: There is provided an implant retaining device, which has the effect of preventing an intervertebral implant from jutting out of the receiving bed. The implant retaining device generally includes a plate having at least one throughbore to receive a screw, and a screw for securing the plate to the vertebrae. The plate may be dimensioned to cover a portion of the opening of a receiving bed, and thus, need only be secured to a single vertebral body. In an alternate embodiment, the plate may be used during bone fracture correction procedures to prevent a bone screw from backing out of engagement with adjacent bone sections. A method of retaining an intervertebral implant using the device is also provided.

    摘要: Instrumentation for manufacturing a bone dowel from human or animal cadaveric bone and instrumentation for evaluating the suitability of the bone and/or dowel for implant use after each step of the manufacturing process is provided. Such instrumentation for manufacturing a bone dowel includes a blanking or coring apparatus, a milling apparatus, a threading apparatus and a tapping apparatus. A gauge is provided to inspect and determine the suitability of the bone dowel at each step of the manufacturing process. By inspecting the dowel being manufactured after each step of the manufacturing process, time and effort which is needlessly wasted during completion of the manufacturing of dowels which are unsuitable for implant use (due to unsuitable bone and/or inaccurate machining of bone) can be avoided. Instrumentation for more accurately positioning bone and the partially manufactured dowel into the instrumentation for machining the dowel is also provided. Such instrumentation includes a gauge for positioning a piece of bone in relation to the apparatus, and mounting blocks for securing the partially manufactured dowel in relation to the milling apparatus.
