Total shoulder endoprosthesis

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.
