CANNULATED INSTRUMENTATION FOR TOTAL JOINT ARTHROPLASTY AND METHOD OF USE

摘要

A method of preparing an intermedullary canal of a bone for total joint arthroplasty including drilling a hole into the intermedullary cavity of a bone and inserting a centering rod (14) longitudinally into the intermedullary canal of the bone. The rod (14) is inserted to align the rod along the longitudinal axis of the bone. Next, the articulating surface of the bone is osteotomized and the intermedullary canal is prepared to receive a prosthesis. The preparation includes placing cannulated instruments in a telescoping manner over the centering rod and into the intermedullary canal to create a cavity suitable for receiving a bone prosthesis. The cannulated instrumentation includes a cannulated osteotomy guide (20, 22), a cannulated reamer (24), a cannulated box chisel (66), and a cannulated broach (28). The instrumentation is also disclosed.
