Our products

Mueller

Over decades, the Müller Straight Stem has been safely used as a hip
endoprosthesis for cemented fixation in the femur and is one of the most commonly used cemented implants worldwide.
Produced from CoCrMo casting alloy (ISO 5832-4) or implant steel (ISO 5832-9) and fitted with a 12/14 cone, the Müller Straight Stem can be combined with both metal and ceramic femoral heads.
One standard and one lateral version, each in 11 different sizes, are available.

The stems differ from one another in terms of length and offset. At 135°, the CCD angle is identical for all stems. The fine groove structure facilitates good adhesion of the cement. Optional cement stoppers limit the depth of the cement. Depressions to facilitate insertion ensure ease of handling. The fine structure of the surface of the implant increases the surface area and optimises anchoring with bone cement.

The modular design of the system allows for optimal individual care of patients, also at an advanced age. The Müller Straight Stem provides primary stability when the joint is under stress, especially in "softer" bones, thus enabling early mobilisation of the patient.
It also covers a wide range of indications and can be used for nearly all primary surgical interventions and also for many revisions.

Expresus

For a cementless treatment of the femur

The OHST OEM Expersus Hip Stem is an artificial hip stem for cementless or cemented fixation inside the femur. 
In the cemented version the Ex-persus Stem is made of CoCrMo wrought alloy (ISO 5832-12) and comes with a 12/14 cone. It has a smooth, fully polished surface and can be combined with both metal and ceramic femoral heads. 

In order to treat the various femoral anatomies of the patients, the hip stem comes in 9 sizes with a standard 125° and standard 135° variant. The body of the stem has a triple tapered shape in order to ensure both self-clamping as well as the necessary rotational stability. 

In the cementless version the Expersus Stem is made of titanium alloy Ti6Al4V (ISO 5832-3) and comes with a 12/14 cone. The shaft can be combined with both metal and ceramic femoral heads. 
Apart from the polished neck area, the cementless Expersus Hip Stem has an all-round titanium plasma spray and hydroxyapatite coating. The coating accelerates growth of the bone onto the im-plant, thereby promoting stable and long-term fixation. 

In order to treat the various femoral anatomies of the patients, the hip stem also comes in 9 sizes with a standard 125° and standard 135° variant. The body of the stem has a triple tapered shape in order to ensure both self-clamping as well as the necessary rotational stability. 

Owing to the availability of both the cemented and the cementless version, there is thus a wide range of possibilities for reconstruction of the natural geometry of the joint taking into account the bio-mechanical parameters centre of rotation, leg length and CCD angle.

ZEN Knee l For a cementless, cemented or hybrid implantation

The ZEN knee system is a highly congruent mobile bearing surface replacement for cemented, cementless or hybrid use. It consists of four components, that are available in several variations: a femoral component, an insert, a tibial and a patellar component. The implant system was developed and tested according to the latest state of the art technology.

The implant components of the ZEN knee system facilitate transmission of an optimal level of power into the adjoining bones and are designed for a surgical technique that is as sparing of bone as possible.

Form and dimensions of the ZEN knee implants are based around the natural anatomy of the knee. Each component is available in six sizes in order to adjust to the individual conditions of each patient.

The range of motion in flexion is over 110° when using an ultra-congruent insert. The standard insert allows an even greater range of motion.

All UHMWPE components (inserts and patella) contain a pin made from implant steel (ISO 5832-1) for better visualisation during imaging procedures.

Primaro Cup for a cementless fiaxtion in the acetabulum

The Primaro Cup is a modular acetabular endoprosthetic
system with TPS coating for cementless fixation in the acetabulum. The hemispherical outer cup with flattening of the poles is made of biocompatible TiAl6V4 alloy (ISO 5832-3). The Primaro Cup is also available with a CaP coating. The outside diameter of the cup sizes ranges from 44 millimetres to 68 millimetres.

The Primaro Cup is available with or without screw drill holes. In the version with drill holes - the holes are sealed when supplied. If requiered, self-tapping flat head screws are available to improve fixation of the outer cup in the acetabulum.
Position marks on the plane surface of the cup allow the alignment of the screw drill holes in the cranio-lateral direction.

About us

Company details

Customer Orientation as a Matter of Principle
OHST considers itself to be a centre of excellence in the area of endoprosthetics. We support manufacturers and distributors – from development to production and logistics. Cost-effective OEM products, proven in many years of everyday clinical practice, round out the range of offerings for many of our customers.

Our continuous growth with constant market proximity and intensive technical development made us one of the leading suppliers in Europe.

The basis for our success is:

  • The continuous dialogue with our customers
  • The high level of motivation and competence of our employees
  • Many years of experience in complex technologies
  • The relevant know-how in all areas of implant technology.
As a genuine partner, we not only share the fruit of our joint effort but also the risk and responsibility.

Precision is human

The quality of our products is due to our inquiring mind, specialized knowledge and commitment of our employees. In our development department engineers and technical drawers work meticulously on ever-improving systems. Product designers give prototypes the final and precise touch and at the workbench skilled mechanics make sure that everything fits. However, only if everybody and finally, the strict final inspection are satisfied, the products go to our customers.
Each of our employees is a specialist of its own. Therefore OHST relies on a high level of education and a thorough training. We train our junior staff ourselves.
But this is not where we stop. Knowledge becomes outdated in ever shorter cycles. Therefore we rely on continuous training.
