Reverse shoulder arthroplasty--minimum age for surgery, postoperative rehabilitation and long term restrictions. A delphi consensus study.

BACKGROUND The aim of this study was to determine if agreement could be obtained on guidelines regarding the ideal minimum age for a reverse shoulder replacement, as well as on post-operative rehabilitation and restrictions imposed on patients having undergone this procedure. MATERIAL AND METHODS A two-round Web-based Delphi consensus study was undertaken. An international group of experts in the field of reverse shoulder replacement were asked to complete the questionnaire. Consensus was considered as agreement of 60% or higher. RESULTS There was substantial disagreement in most parameters examined amongst the 10 participants of the first round. Agreement was achieved for most parameters examined amongst three of the four respondents of the second round. CONCLUSIONS 1. Amongst respondents of the second round a minimum age of 65 years for reverse shoulder arthroplasty was considered acceptable for most areas examined. 2. Controversial management areas in reverse shoulder arthroplasty have been highlighted and require exploration by further clinical studies.
