    摘要： This invention relates to a spinal fusion system and method for use as a prosthetic implant. The system and method includes a housing dimensioned to be situated between adjacent spinal bones, such as adjacent vertebrae. The housing cooperates with the spinal bones to define a graft area for receiving graft material, which may be inserted anteriorly into the housing during a surgical operation such as a vertebrectomy or discectomy. A housing may have various features such as migration preventers to prevent the housing from migrating posteriorly towards a spinal column during or after insertion of the housing; a plurality of projections or crossbars may be removably inserted into the housing and can be used with a cover that permits the housing to “float” relative thereto.

    摘要： An apparatus and method of use directed towards protective and supportive hole caps for prosthetic implant devices are disclosed. The present hole cap supports a prosthesis and provides a physical barrier between the prosthesis and underlying bone matter. In a preferred embodiment, the hole cap includes at least one compression spring formed along the perimeter of the cap. The compression spring maintains the hole cap within a counter-bored hole after the hole cap is inserted within the counter-bored hole. In accordance with the present invention, the compression spring deflects slightly towards the center of the hole cap when the cap is inserted within the counter-bored hole. The compression spring provides sufficient compression force against the sidewalls of the counter-bored hole to thereby hold the hole cap in place within the hole. The counter-bored hole is preferably shaped to snugly receive the outer perimeter of the hole cap. Alternative configurations are disclosed for maintaining the hole cap within an associated hole formed in the implant. The hole caps are used for covering holes in implants affixed to a patient's body with or without the use of bone screws. The hole caps prevent the flow of unwanted debris into the counter-bored hole and into the patient's underlying bone matter.
