Bicontact® Hip Stem System

Bone preservation. For years to come.

The Bicontact® philosophy is maximum preservation and protection of the existing bone substance. Based on the simple but crucial fact that the success of the prosthesis fixation depends on both – implant and bone. To do this, instruments were developed that compress the bone instead of removing it. The Bicontact® system comprises various stem types – for different anatomic morphologies.

The Bicontact® Hip Endoprosthesis System:

The bone preserving operation technique for cementless or cemented implantation. For primary and revision surgery.

Different bone shapes. Various design solutions.
The Bicontact® implant range comprises stem types for different bone morphologies. Normal, dysplastic and very tight conditions in the marrow cavity.
For normal medullary canal conditions, the Bicontact® stem design offers the standard stem type S or type H (high offset). For smaller bone conditions the Bicontact® SD stems are the suitable choice. For exceptional cases such as extremely severe dysplastic changes with very narrow conditions in the femoral canal, the range of Bicontact® N stems can be chosen.
The design solutions differ mainly in the upper medial section, which is responsible for anchoring the prosthesis. For all stem types, the distal stem is tapered into a flat, tapered end.

Bicontact® stems for cementless or cemented implantation: Coming to the right decision during the operation.
The situation found during the surgery enables or determines the right choice of procedure. The surgeon is free to make a decision, not only before, but also during the operation.
With Bicontact® the possibility exists to decide intraoperatively whether to perform a cementless implantation or to implant with bone cement. The Bicontact® stem can be anchored in the bone either by making use of the Plasmapore® surface or by applying the most recent cementing techniques.

The modern Bicontact® implantation instrument combines many years of experience, proven methods and the support of correct intraoperative decisions for a reliable treatment of the hip joint.
One and the same procedure for all Bicontact® stem types – cementless or cemented.

The Bicontact® can be implanted with the Osteoprofilers in a minimally invasive procedure. As a muscle sparing measure, the trochanteric wing is only prepared in a last step.
The user can choose between two rasp versions: the A & B Osteoprofiler or the compact profiler that combines the A&B Osteoprofiler in one single rasp.  

The revision of a hip prosthesis requires a particularly careful procedure. The revision should preserve as much substance as possible and support the reconstruction of the bone. For a revision the implant requires bone substance, for stable fixation. Therefore, the principle of Bicontact® revision is: bridging the defect zones. With secure locking with screws, if necessary. And, of course, with the proximal Bicontact® design with different stem lengths, straight, curved or SD type for narrow bone conditions.

Computer-assisted planning and operation procedures help the surgeon in modern hip replacement. Intelligent instruments support his manual skills. In this way, experience and operating techniques are developed further. Implanting a hip prosthesis requires manual skill and making the right intraoperative decisions. By using OrthoPilot® navigation system, the surgeon gains implantation data, which he can compare to his operative procedure, in all surgeries especially the ones where he encounters some difficulties.
