ProvenFit Stem
Cemented fixation has excellent clinical results in a long term clinical follow up. It is a durable, reproducible and cost-effective technique. In the 1970s Maurice Muller designed one of the most successful cemented prosthesis, “The Muller stem”. Vadin Implants offers a generic version of the prosthesis in CoCr and SS medical alloys.
Prosthesis Geometry:
- Standard and lateral versions available
- Cone 12/14
- CCD-angle 135 degrees
- Conical design
Material:
- FeCrNiMnMoNbN (ISO 5832-9): advanced nickel-reduced, high-strength stainless steel
- CoCrMo (ISO 5832-12): Cobalt material without nickel as alloying element
The material should be selected according to patient’s individual needs. CoCrMo decreases the risk of the potential allergic reactions. The mechanical properties such as strength and Young’s modulus are comparable to other materials.
Features and Benefits of the ProvenFit Stem:
• “Proven concept”-philosophy: stem geometry and fixation.
• Several million of stems have been implanted worldwide over the last 30 years.
• Excellent long-term clinical results and scientific publications in well respected journals.
• Cemented stem is “gold standard“, especially in older patients.
• Easy, reproducible and proven surgical technique.
• Extraordinary cost-performance ratio.
