Since 1982 the SM straight shaft hip endoprosthesis made of a cobalt chrome cast alloy (CoCrMo, ISO 5832/4 ASTM F75) has been implanted successfully thousand-fold. Clinical reliability and simple, flexible handling combine with high economy at this implant.

The thought out and simple to be handled instruments make a fast and efficient operative approach possible. A variety of application possibilities arises from the modular erection of the system both in the cementable range and in the hybrid version with the acetabulum components without cement.

The SM straight shaft hip endoprosthesis shows a CCD corner of 135° and is available in four shaft strengths with or without collars in the cone size 12/14 respectively.
