Cemented Hip
In the 1960’s Sir John Charnley who worked at Wrightington Hospital, Wigan, produced a total hip replacement. Prior to this attempts had been made to replace the hip using ceramic or glass femoral heads but it was Sir John Charnley, both an engineer and surgeon, who designed and used hip replacements that have, with the passage of generations, become the most popular today. Cemented hip replacements have a cup that fits into a pelvic socket or acetabulum and will also have a femoral stem that fits into the femoral shaft and on the top of this stem will be a ball that articulates with the acetabular component.
What happens during total hip surgery?
Initially in England the emphasis was on using cement as this was the way the Charnley hip was made. Another popular hip is the Exeter hip. This is again uses cemented, the cement is used to fill the gap between the implant and the bone. The cement does not work as an adhesive but as a filler.
