BACKGROUND: Complex @entity6342 are very difficult to treat particularly in @entity1 older than 65  years with an @entity79 compromised. The goal of this paper is to evaluate radiological outcomes at mid-term follow-up of proximal humerus @entity174 treated with reverse shoulder arthroplasty using a dedicated @entity174 stem. MATERIALS AND METHODS: The study population included 98 @entity1 who underwent reverse shoulder with a dedicated @entity174 stem for an acute proximal humerus @entity174 ; 87/98 @entity1 were available for analysis. There were 62 female and 25 male @entity1 , and the mean age was 76.2  years at the time of surgery (range 61-90  years). Clinical and radiological outcomes were evaluated at a mean follow-up of 27  months after surgery. RESULTS: Average active elevation was 137.7  , external rotation 29.1  , and internal rotation 40.7  . Overall, the @entity2916 healing rate was 75  %. There was a significant increase in active anterior elevation, external rotation, and internal rotation among @entity1 who demonstrated radiographic evidence of @entity2916 healing. All @entity2916 nonunions (21 cases) occurred preferentially in females, but this number did not reach statistical significance. CONCLUSION: RSP using a dedicated stem is a very viable solution to treat complex humerus proximal @entity174 . Reliable restoration of elevation can be expected. However, in @entity1 in whom @entity2916 healing occurs, a better active elevation other than restoration of active rotational movement can be observed.
