Thesis of Ms. Franziska Hühn(TiHo).
Were examined the straight stem prosthesis and  Spiron ®- femoral neck prosthesis Zweymüller type on dog bone at the University of Veterinary Medicine Hanover(TiHo). The results show higher by about 50% stability of the system [+ bone Spiron ®] against the system [+ bone type Zweymüller prosthesis](TiHo). The higher stability of the Spiron ® prosthesis is explained by the nature of the breaking out of the two different types of prostheses in case of overload(TiHo). The Spiron ® prosthesis breaks the femoral neck consists of the trochanter out massively, while the conventional prosthesis destroys the bone through a crack(TiHo). Furthermore, the studies show that the bone with Spiron ® prosthesis is much more elastic than bone with a conventional prosthesis. This results in a greater insensitivity to shocks(TiHo).
