title: Cost of implanting a cemented versus cementless femoral stem.
abstract: Fifty stratified unselected cases of primary uncomplicated total hip arthroplasty performed at the total joint service of a university teaching hospital were examined. In 25 cases, the femoral stem was implanted with cement, and in the other 25, a cementless stem was implanted. For cemented stems, third-generation cement technique was used, including centrifugation. The average cost to the hospital for a cementless stem was $900 greater than for a cemented stem. The total cost to the hospital for accessories used to achieve modern cement technique was over $700. The operative time for implanting a cemented stem averaged 20 minutes longer, which resulted in an additional operating time charge of $270 and an additional anesthesia charge of $100. When these charges are added to the cost of cement and accessories, the actual cost to the hospital for implanting a modern cemented stem was greater than for a corresponding cementless stem.
