The field of shoulder endoprostheses has undergone rapid development in the last few years. Based on many years of very positive experience with the Articula® prosthesis, the next generation, Affinis® Fracture, has now been developed.
The aim of fracture prosthesis is to restore mobility and to eliminate pain, so that the patient can manage the activities of everyday life. A main objective here is the anatomical reconstruction of the rotator cuff, which is achieved through the precise and secure fixation of the tuberosities to the shaft of the humerus and the prosthesis.
You can continue to rely on the existing benefits such as continuously variable adjustment of height and retroversion, as well as primary stability provided by the spikes. Based on CT-models the prosthesis has been anatomically redesigned. Additionally the latest findings in refixation techniques have been incorporated. On growth of the tuberosities is furthermore improved by the newly added bioactive CaP coating.
Advantages of the system
- Bioactive coating for active on growth of the tuberosities
- Continuously variable adjustment of height and rotation
- Simple, precise instrumentation
- Anatomical shaping: exact, stable fixation of the tuberosities, volume of the metaphysial part replaces the zone of comminuted fracture
- Lateral refixation hole for anatomical reintegration of the tuberosities close to the head
- Primary cementing of the stem (no trial prosthesis required)
- Polished medial and lateral hole for secure and frictionless threading of thread or cable
- Compatible with optional eccentric heads
- Optimum ligamentous balance
One step further
The anatomical shaping and the spike structure have now also been adopted for other fracture endoprostheses.
With the Affinis Fracture, we are now taking the next innovative step. The focus is on improving the problem of the high number of vanishing tuberosities, which has remained unsolved to date.
Besides the stable refixation and the prosthesis design, a leading role is also played here above all by the bioactive coating of the central component. Through the porous surface structure, blood cells are attracted, which support bone growth. The calcium phosphate is converted into endogenous bone in a very short space of time (approx. 6 weeks), which leads to greatly improved adhesion of the tuberosities.
The principle: Anatomical-biological healing
Important factors in biological support for anatomical healing:
- Multifragmentary and comminuted fractures of the head of the humerus, with the threat of ascularisation disorders of the fragments
- Fractures of the proximal humerus that cannot be treated osteosynthetically
- Secondary fragment dislocation following osteosynthesis in the proximal humerus to preserve joint function
- In certain tumour-related modifications of the proximal humerus
