ORTHOPAEDICS - The initial stability of cemented and non-cemented femoral stems fixated with a bone grafting technique

Cemented stems are said to reach a better initial stability, probably by cement penetrating in the graft layer. For non-cemented stems used in combination with the grafting technique developed, additional means to guarantee initial stability are said to be needed.

To reconstruct intramedullary bone stock in revision surgery of failed total hip arthroplasties, a method was developed using impacted trabecular bone grafts. In an in vitro model in the femora of the goat, the initial stabilities of both cemented and non- cemented hydroxyapatite-coated stems in …
