Identifit: a silicone mould used to intraoperatively construct a cementless femoral stem.
A new system named Identifit to construct a femoral stem for use in hip arthroplasty is presented: a silicone mould of the femoral canal is made, and while the surgeon proceeds to insert the acetabulum, in a laboratory located annexed to the surgical theater the mould is used to make a titanium stem in the same shape. The stem is anatomical with a mean value for bone to prosthesis contact equal to 94%. The first results obtained seem to confirm the theoretical effectiveness of this system.
