title: Reverse shoulder prosthesis to treat complex proximal humeral fractures in the elderly patients: results after 10-year experience.
abstract: OBJECTIVE
  The aim of this study is to report the clinical and radiological results of reverse total shoulder arthroplasty (rTSA) in elderly patients who have been treated for complex humeral fractures.
  
  
  METHODS
  From January 2005 to December 2014, we have implanted rTSA for proximal humeral fractures in 95 patients (80 women, 15 men) about 75 years old on average (range 62-95 years). All rates and results on intraoperative and postoperative complications have been collected in a specific database. In all cases we have used a modular implant prosthesis (Lima Corporate, San Daniele del Friuli, Italy). The prosthesis was implanted cementless in 92 cases. Because of the presence of a high percentage of comorbidities in the elderly patients, we have retrospectively analyzed the necessity of a secondary hospitalization, from a week to a 6-month time after the discharge, due to general health problems and specific postoperative shoulder complications. The mean follow-up was 5 years (range 1-9 years) for 70 of 95 patients, 50 of whom had adequate radiographic controls.
  
  
  RESULTS
  None of 95 patients has required a reoperation or a hospitalization for general health problems from 1 week to 6 months postoperative. No early or late infection of prosthesis has been observed. There were seven cases of perioperative complications, three humeral vertical bone fissuring, two glenoid fractures and two cases of deltoid muscle damage. We have had three cases of postoperative hematoma and one case of ulnar nerve neuropathy. The mean constant score was 85.4, and the mean simple shoulder test was 7.4. We have observed a grade 1 scapular notching in 15 cases (30 %). In the remaining 35 reviewed cases, there was no notching. Peri-articular heterotopic ossifications were found in 11 cases (22 %).
  
  
  CONCLUSIONS
  Reverse shoulder prosthesis in complex humeral fractures in the elderly can be considered as a reliable surgical procedure, which leads to very good clinical and radiological results in case of cementless prosthesis, as well.
