Primary Outcome Measures

Name	Time	Method
Assessment of the loss of internal rotational force in comparison of the groups of preserved versus recessed subscapular muscle after implantation of an inverse shoulder prosthesis, the preoperative force being used as a reference. For this purpose, data is collected on the day of admission before the planned operation and during the follow-up examinations for 3, 12 and 24 months.

Secondary Outcome Measures
