Salvage reverse total shoulder arthroplasty for failed operative treatment of proximal humeral fractures in patients younger 60 years: long-term results
2019
Hypothesis Is salvage reverse total shoulder arthroplasty (RTSA) a justifiable treatment for failed operative treatment (open reduction–internal fixation [ORIF] or primary and secondary hemiarthroplasty) of proximal humeral fractures in patients younger than 60 years? Methods Thirty patients (mean age, 52 years; age range, 30-59 years) were reviewed after a mean follow-up period of 11 years (range, 8-18 years). Of the patients, 7 (23%) underwent RTSA for failed ORIF and 23 (77%) for failed hemiarthroplasty. Clinical and radiographic outcomes were assessed longitudinally. Results At final follow-up, the mean relative Constant score had improved from 25% (±12%) to 58% (±21%, P Conclusions Salvage RTSA in patients younger than 60 years is associated with a high complication rate. It leads nonetheless to substantial and durable improvement beyond 10 years, provided the complications can be handled with implant retention. Inferior shoulder function is associated with greater tuberosity resorption or resection and inferior overhead elevation with the diagnosis of failed hemiarthroplasty.
