Methods: In this retrospective study, 20 patients (17 female, 3 malemean age = 71.35 yearsage range = 54-81 years) who underwent RTSA for FTPHF between 2012 and 2018 were included. The mean follow-up was 37.85 (range: 24-83) months. Outcome measures included shoulder range of motion, Constant score, ASES (American Shoulder and Elbow Surgeons) score, visual analog scale (VAS). Intra-or post-operative complications were also recorded. Results: The mean anterior flexion and external rotation improved from 37.25 degrees +/- 10.59 degrees and 11.05 degrees +/- 4.79 degrees preoperatively to 105.53 degrees +/- 9.33 and 22.37 degrees +/- 4.12 degrees postoperatively, respectively (P < 0.01 for both). The mean Constant and ASES scores ameliorated from 21.95 +/- 3.57 and 18.15 +/- 4.69 preoperatively to 61.7 +/- 7.6 and 71.18 +/- 4.69 at the final follow-up, respectively (P < 0.01 for both). VAS significantly reduced from 6.83 +/- 2.04 preoperatively to 1.79 +/- 0.61 at the final follow-up (P < 0.01). None of the patients had major complications or required revision. Conclusion: Treatment with the RTSA for the FTPHF seems to be an effective treatment method that can provide satisfactory radiological and functional outcomes with low complication rates.Reverse total shoulder arthroplastyFailed proximal humerus fracturesFracture sequelaeClinical and radiological assessmentArticleWOS:000768953900005
