Primary hip stems uncemented

Alloclassic® Hip
Classic proven design with superior clinical results
Since 1986, the Alloclassic has become the most used, primary, cementless hip in the world with more than 325,000 cases performed.  Surgeons praise its technically simple application, outstanding short and long-term stability, and excellent clinical results.  Studies show 99% survivorship at 10 years.

CLS™ Hip Stem
A standard for proximal press-fit design
With over fifteen years of excellent clinical results, the CLS Hip Stem has become a standard for proximal press-fit designs. The CLS Stem is a grit-blasted titanium alloy, cementless stem. Tapered fins are designed to optimize proximal fixation in cancellous bone while a tapered, rectangular cross-section provides excellent rotational stability distally. Long-term follow-up shows a 98.6% implant survivorship at 10 years.

Fitmore® Hip Stem

Inspired by individual anatomy

Optimal reconstruction of offset is a crucial part of today’s Total Hip Arthroplasty. Conventional stems often fail to match individual anatomy. In most cases offset is linked to stem sizing and as a result, one’s ability to restore natural joint kinematics can be limited.

Given today’s younger and more active patients consideration was also devoted to preservation of muscle insertions and bone in the region of the greater trochanter and compatibility with less-invasive surgical techniques. The curved stem shape meets both requirements and eases implantation. <<read more>>

Avenir® Müller Stem 
Combining elements from the past and the present, the Avenir-Müller stem is a modern solution for total hip arthroplasty.The stem reverts to the well-known design of the M.E. Müller Straight Stem, a design that evidentially achieves primary stability very easily. Thanks to the proximal chamfer the stem is very MIS friendly. The HA coating offers excellent secondary stability and the accurate instruments ensure an easy implantation.There is no doubt that this modern system will proof itself over the next years, making the Avenir stem a favourable solution for young and old patients.

Metabloc™ Stem 
Philosophy
The Metabloc straight stem system was developed on our experience of well known and successful hip replacement designs.Two proven anchorage philosophies - uncemented and cemented - are combined in one stem system and can be implanted with the same instrument set. Read more >

Wagner Cone Prosthesis™ Hip Stem 
The Wagner Cone Prosthesis was developed with Professor Heinz Wagner and implanted for the first time in 1990. The prosthetic stem has a conical fixation which is derived from the positive experience of over 15 years made with the SL Revision Prosthesis. Its cone angle of 5º closely corresponds to the natural morphology of the proximal femur. Eight longitudinal ribs ensure a high degree of rotational stability. Read more >
