摘要： The present invention is an apparatus and method for stabilizing the facet joints of the spine. One aspect of the present invention is the stabilization of the facet joint by insertion of a facet implant through two opposing facet surfaces. The facet joint is not fixedly frozen by insertion of the screw, but instead the facet surfaces are flexibly and movably anchored to preserve movement because the screw or anchor includes a flexible intermediate portion which is positioned between the facet surfaces. The facet implant may be in the form of a screw or other anchor with the intermediate portion in the form of a polyaxial head, a cord, a spring, etc. The facet implant may furthermore be used in conjunction with a facet spacer that is placed between the first and second facet.

摘要： Medical implants are formed at least in part from porous metal wherein the pores of the metal are filled with a hardenable material. The hardenable material can be used to assist in the manufacture of the implant, permitting detailed machining of the implant. Further, the hardenable material can be a resorbable material that strengthens the implant during implantation but is resorbed, once implanted, to permit bone growth and infiltration. Further, in an alternate embodiment, the hardenable material can be a thermoplastic material that can be heated by ultrasonic energy to create an adhesive bond between a fastener and bone structure.

摘要： The present invention is an apparatus and method for stabilizing the facet joints of the spine. One aspect of the present invention is the stabilization of the facet joint by insertion of a facet implant through two opposing facet surfaces. The facet implant includes a proximal, distal and intermediate member. The distal member is inserted through the facet joint and into a facet surface. The intermediate member is then placed in the area between the facet surfaces. The proximal member then is brought closer to the distal member to deploy the intermediate member into the space between the facet surfaces. Once deployed, the intermediate member provides a cushioning or restoring force to the facet joint such as to stabilize movement of the joint.

摘要： A tool for extracting broken or otherwise damaged screws from bone or wood includes an elongated shaft having a tool engaging head on an upper end to allow rotational force to be applied. The other end includes an opening which includes tapered cutting threads that are sized to initially pass over the screw to be removed which will cut into and hold onto the screw upon turning the tool opposite to the threads of the screw. The other end opening defines a hole saw which will cut away the bone or wood around the screw to allow the inner cutting threads to engage the screw.
