[Conversion of anatomic to reverse shoulder arthroplasty : Does it make sense?]

We can observe increasing numbers for the implantation of shoulder endoprostheses in developed industrial countries. This is accompanied by a certain number of revision surgeries. The conversion to reverse arthroplasty systems is by far the most common revision procedure. Depending on the primary implant and the individual situation, the surgical effort and consumption of resources can be substantial. Particularly favorable revision scenarios exist in the conversion of stemless primary implants that are part of a platform system and allow a partial exchange and easy conversion from anatomical to reverse implants.
