Two-Year Results After Exchange Shoulder Arthroplasty Using Inverse Implants

This prospective study analyzed the results of exchange shoulder arthroplasty (revision indications) using a Delta Prosthesis (DePuy Orthopaedics Inc, Warsaw, Ind). Exchange replacements using inverse of shoulder implants is a standardized procedure used to treat impingement, restricted range of motion, joint instability, and infection.

The complication rate is low and patient satisfaction is high. Little correlation exists between the score value and patient satisfaction due to the fact that the main benefit to the patient is immediate pain relief. Consequently, the functional result, which has a considerable effect on the score value, was only of secondary importance to the patients. The need for nursing care of elderly patients can be avoided and the almost maxi- mum functional result is achieved at a very early stage, i.e., as early as three months after surgery.1,4,5A disadvantage of this procedure, however, is the high cost of the implant.
