Affinis Anatomic
Total shoulder endoprosthesis.
Adjustment for restoration of the centre of rotation [1]
Simple instrumentation
Suitable for adaptation to post-traumatic malpositions [1]
About
The Affinis total shoulder endoprosthesis, with its double eccentricity – a movable cone and eccentric head – allows the centre of rotation of the head to be restored in a simple and anatomical manner [1, 2]. Less polyethylene wear can be anticipated in combination with the vitamys glenoid components than with the UHMWPE components [3].
The Affinis prosthesis is also ideal for treating post-traumatic malpositions [1]. It can be easily adjusted to the anatomic conditions, which facilitates restoration of the centre of rotation [2]. Through the movable cone and the eccentric head, the proximal humerus can be anatomically reconstructed [1, 2].
The simple instrumentation enhances the advantages of this shoulder endoprosthesis: Resection is performed under retrotorsion monitoring, the rasps are used as test prostheses and the reconstruction of the centre of the head is simple and logical [1, 2].
Affinis is available in cemented and uncemented versions.
