Abstract: A multipart intervertebral implant is provided which includes an implant portion and an implant extender portion. The implant portion and the implant extender portion can be fastened together using any known fastening means including pins, interlocking structure (e.g., dovetail, tongue and groove, etc.), adhesives, etc. The size of the implant extender portion can be selected during a surgical procedure to provide an implant suitable for a particular intervertebral receiving bed. An intervertebral implant is also provided which may be formed from a multiplicity of implant sections which are fastened together to provide an implant having a desired length. Implants having surface configurations which more closely correspond to the configuration of vertebral endplates are also provided.

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.

Abstract: The present invention provides a tibial prosthetic knee component. The prosthesis includes a tibial tray having a posterior rail and an anterior rail, and a tibial insert. The tibial insert has a posterior dovetailed surface matching the posterior rail in the tibial tray, and an anterior surface matching the anterior rail in the tibial tray. The posterior rail of the tibial tray and the posterior dovetailed surface of the tibial insert are curved to provide clearance for the posterior cruciate ligament. A retaining clip is provided for retaining the tibial insert in the tibial tray. The clip includes a tab which extends through the tray into the insert and a resilient holding member remains unloaded when loads are applied to the knee, reducing the likelihood of dissociation of the tray and insert.
