Uncemented prosthetic hip implants are dependent on excellent primary stability to achieve osseointegration and long-term stability. It is recognized that excessive micromotion at the bone-implant interface is associated with formation of a soft tissue and loosening of implants. Micromotion above 40μm leads to partial bone ingrowth, while values above 150μm completely inhibit bone ingrowth. The main concern in short femoral stems is that stability might be compromised. This might be due to the relatively less contact surface. There are no long term results on stability of short femoral stems available, but in vitro studies shows no significant reduction in stability of prostheses with comparable stem length to the Furlong Evolution.
