IMPROVED BONE-TENDON-BONE ASSEMBLY WITH CANCELLOUS ALLOGRAFT BONE BLOCK

摘要

The invention is directed toward a bone-tendon-bone assembly extended between two shaped cancellous bone blocks (30) and a method of inserting same in a joint. Each substantially cylindrical shaped cancellous bone block (30) has a central through going bore (32), a flat exterior longitudinal surface (34) and a channel longitudinally cut in the exterior of the bone block body (30) opposite the flat longitudinal surface. A tendon replacement is inserted through the central through going bore (32) around the end of each block and looped back along the flat longitudinal side (34) with each block (30) being in a reversed orientation position as to the other block. A channel cut in the exterior surface of each block is adapted to receive an interference screw to keep the block anchored in a bone tunnel previously cut in the respective bones of a joint.
