A SPINAL FUSION SYSTEM AND METHOD FOR FUSING SPINAL BONES

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.
