Based on principles described by Prof. Dr. Karl Zweymüller and other Authors
The Series 150 stem is a cementless double tapered hip endoprostheses made of forged titanium alloy TiAl6V4 with rectangular profile. The design of this hip stem is based on the biological cortical anchorage principles described by Prof. Dr. K. Zweymüller and other authors in numerous publications associated with excellent long-term results over the last 25 years. The Series 150 stem is available in 12 Sizes with 2 different CCD angles (123° and 131°). Taper: 12/14. The stem is manufactured of high quality titanium alloy (Ti6AlV4).
Biological Cortical Anchorage
by large-area cortical force transmission
Excellent Rotational Stability
by double tapered straight stem with rectangular profile and proximal lateral trochanter wing
by biological integration of the hip stem into the bone structure (Osseointegration) due to the rough-textured surface
