[Grammont reversed prosthesis for acute complex fracture of the proximal humerus in an elderly population with 5 to 12 years follow-up].
Aim of this retrospective study was to analyze outcome in 23 cases of Delta III reverse ball-and-socket total shoulder prosthesis for acute complex fractures of the proximal humerus in an elderly population with poor bone quality. In such a population, this procedure could escape the difficulties of a reliable and efficient refixation of the tubercles. ⋯ For acute complex fractures of the proximal humerus in elderly subjects with poor bone quality, when an efficient and reliable re-fixation of the tubercles is difficult or impossible, reverse ball-and-socket shoulder prosthesis is a possible alternative providing good functional outcome except for rotations but with the risk of inferior scapular notching. Although not problematic in the mid term, these notches may contribute to glenoid loosening with bone loss in the long-term. Nevertheless, this procedure seems to improve the status of patients with such fractures.

[Bipolar shoulder prosthesis for rheumatoid arthritis with irreparable rotator cuff tear: results after 5 years' follow-up].
The goal of this study was to assess the clinical and radiological outcome of bipolar shoulder prosthesis in twelve shoulders with rheumatoid arthritis (RA) and irreparable rotator cuff tears. ⋯ Some massive tears involving the subscapularis tendon can lead to anterior recurrence after bipolar shoulder prosthesis. They might be a limit to the procedure and require a reversed shoulder prosthesis or a glenohumeral arthrodesis.
