Abstract: A connection system is provided that joins a revision fixation plate to a previously implanted skeletal fixation plate. In one form, the system allows the previously implanted plating system to be revised without disturbing the original implant components. In one aspect, the connection includes joining the revision fixation plate to a previously implanted fastener. In another aspect, the revision fixation plate is directly joined to a previously implanted fixation plate. In yet another aspect, the connection includes forming a dynamic relationship between the previously implanted plating system, the revision fixation plate, and the affected vertebrae. In one form, the dynamic relationship enables movement between the previously implanted plating system and the affected vertebrae and in another form, the dynamic relationship enables movement between the previously implanted plating system and the revision fixation plate.

Abstract: A spinal stabilization system, apparatus, and method are disclosed which include an interconnection mechanism for engaging stabilization members to one another. In one embodiment, the interconnection mechanism comprises a locking member having first and second threaded segments. An anchor member is provided having an upper segment and a lower segment, wherein the lower segment is structurally configured for engagement with a respective bone segment. A first stabilization member is connected to the upper segment of the anchor member. A locking member is engaged with the anchor member such that the first stabilization member is fixedly secured to the anchor member by a lower portion of the locking member having a first threaded segment. A second stabilization member is connected to an upper portion of the locking member by a cap that is threaded onto a second threaded segment of the locking member.

Abstract: A prosthetic screw system that includes a prosthetic screw for at least partial insertion into a bone and/or cartilage. The prosthetic screw includes a head and a lower portion connected to the head. The prosthetic screw system also includes a set of head-pieces that can be connected to the head of the prosthetic screw. The head-pieces have differing configurations that are designed to be connected to different types of components of a prosthetic system. The universal connection arrangement between the prosthetic screw and the set of head-pieces enables the prosthetic screw to be customized for connection with a variety of components of a prosthetic system. The head-pieces can alternatively or additionally include a mechanical and/or electrical mechanism that provides one or more substances (e.g., medicine and/or other biological agent, etc.) and/or electrostimulation to a surgical site.

Abstract: An improved spinal surgical implant used primarily in the posterior aspect of the spinal column for spinal reconstruction; revision surgery; deformity correction; and/or tumor surgery and/or trauma surgery of the cervical, thoracic and/or lumbo-sacral spine.

Abstract: An implant and sleeve combination for at least partial insertion into a bone and/or cartilage. The implant includes a lower portion and the sleeve includes a cavity designed to at least partially receive the lower portion of the implant.

Abstract: An improved prosthetic implant for forming a rigid structure between adjoining vertebrae in a spinal column. The prosthetic implant includes a cage having a top, bottom, front end, back end, first side and second side walls. The first side wall has an arcuate surface. The top and bottom wall include one or more ridges to engage a surface of an adjacent vertebrae. The top and bottom wall also include an opening to receive packing material such as medicine, human tissue and the like. The top and bottom walls also incline simultaneously in two directions.

Abstract: A pedicle screw for at least partial insertion into a bone and/or cartilage. The pedicle screw includes a head and a lower portion connected to the head. The lower portion includes at least one interface that designed to at least partially discharge an electrical current, and/or a medical substance to or adjacent to the bone and/or cartilage.

Abstract: A method, apparatus and kit for preparing and performing a surgical procedure includes providing a medicinal composition having an autologous tissue medium and a therapeutic agent. the medicinal composition is then delivered to a surgical site in a patient before closing to reduce postoperative pain, provide an interpositional membrane to prevent or inhibit the formation of scar tissue, and/or promote hemostasis. The medicinal composition is suitable for use in a variety of types of surgery, and has particular application in bone or tissue grating and orthopaedic surgery, expecially spine surgery.

Abstract: A customized prosthetic implant and method for producing a customized prosthetic implant for use in fully or partially replacing bone and/or tissue in a human or animal. The custom prosthetic implant is produced by obtaining information about the site of implant for the prosthetic implant, processing the obtained information to generate information on the size and shape of the prosthetic implant, and transferring at least a portion of the generated information to a molding machine to at least partially form the custom prosthetic implant from a moldable compound.
