Primary shoulder reverse arthroplasty: Surgical technique

AbstractTotal reverse shoulder replacement is now a very common surgical procedure that has been shown to be effective in the treatment of rotator cuff tear arthropathies or massive rotator cuff tears with pseudo paralysis, even without arthritis. However, the survival curves of the oldest series decrease between 8 and 10 years after arthroplasty (events: implant survival, or worsening of clinical outcome) which explains why the indication for this type of arthroplasty is usually limited to patients over seventy. Moreover, details and technical modifications have been suggested to improve the surgical technique, the quality of fixation and the mechanical conditions of this non-anatomical prosthesis to improve clinical outcome and implant survival. Within the framework of primary surgery, excluding traumatic or revision surgery, the primary indications for this option are massive rotator cuff tears with (or without) osteoarthritis and primary osteoarthritis with rotator cuff tears and/or with severe glenoid wear and finally, rheumatoid arthritis. The purpose of this conference was to assess and describe the most important preoperative criteria and surgical conditions necessary for this procedure as well as specific technical details about the surgical procedure itself based on available options and options under evaluation such as the positioning of the glenoid component (lateralization, bone graft, orientation) and the association of muscle transfers
