Affinis Fracture / Affinis Fracture Inverse
The Affinis Fracture and Affinis Fracture Inverse shoulder prostheses and associated surgical technique provide a flexible and modular treatment platform for proximal humerus fractures with a simple instrumentation.
Proven concept with new features
Variable adjustment of height and rotation, simple and precise instrumentation, additional lateral refixation hole, primary stem cementing without trial prosthesis, optional eccentric heads
Anatomical-biological healing
Thanks to bioactive coating for active on growth of the tuberosities, anatomical design, maximum primary stability and reduced impairment of blood circulation
One step further
Focus on improving the problem of vanishing tuberosities, thanks to the bioactive coating of the central component
About
Treatment with Affinis Fracture or Affinis Fracture Inverse is indicated in fractures of the humeral head which are difficult to reconstruct. The modular platform system allows intraoperative decision-making and the conversion from a hemiprosthesis to an inverse prosthesis and vice-versa.
Treatment with Affinis Fracture or Affinis Fracture Inverse is indicated in fractures of the humeral head which are difficult to reconstruct. The modular platform system allows intraoperative decision-making and the conversion from a hemiprosthesis to an inverse prosthesis and vice-versa.
The Affinis Fracture System is based on a cemented stem and allows conversion after poor healing of a primary implant into an inverse prosthesis. A securely anchored stem can be left in situ. In addition, the modularity allows the surgeon to decide between a hemiprosthesis or an inverse prosthesis during surgery.
A proven spike surface structure, covered with a bioactive calcium phosphate coating, supports tuberosity anchoring: The calcium phosphate coating remodels into autologous bone within 6 to 12 weeks after implantation and promotes quick osseointegration [1].
The middle component on the humeral side of both versions allows continuous height adjustment on the stem up to 10mm; the retroversion can also be freely adjusted. With these options the patient's individual ligamentous balance can be taken into account.
