Prosthesis Stem

For our object focus this month we are looking at prosthetics. This stem of a prosthesis was designed by Sir John Charnley, a man who pioneered the hip replacement operation, and was cemented in place into the thigh bone. Variations on the design constantly evolved, and it was hoped that the flanged design and unpolished surface in this example would help in the bonding process. Long term studies still debate the pros and cons of each design variation.
