Clinical Results and RSA Migration Analysis of the GLOBAL ICON - Stemless Anatomic Shoulder

The primary goal of the clinical trial is to determine that the GLOBAL ICON implant system from DePuy does not exhibit worse shoulder function after 2 years than the SIMPLICITY from Wright Medical. The primary endpoint is the Constant-Murley Shoulder Score (CMSS) of the implant after 2 years, the non-inferiority of which is to be demonstrated in comparison with an already established prosthetic system (SIMPLICITY, Wright Medical). As secondary endpoints, the migration behavior of the humeral components over time will be determined by radiostereometric analysis (RSA), the further clinical-functional results and the satisfaction of the patients treated will be investigated. Clinical outcomes are measured using standardized and reproducible clinical scores (Oxford Shoulder Score -OSS and Short Form Health 36-SF-36 v1.0 ) at each time of examination. Other endpoints include revision rate within the follow-up period, surgical time (incision to suture), and delays in surgical procedures due to instrumentation. The times of data acquisition are the admission day before the operation to determine the preoperative status, the discharge day and the follow-up appointments after 3 months, 6 months, 12 months and 24 months to determine the postoperative status and course.
