Predictive prognostic factors in patients with proximal humeral fracture treated with reverse shoulder arthroplasty

Abstract

Background We aimed to evaluate the predictive determitants in patients with PHF who were treated with reverse shoulder arthroplasty (RSA) by evaluating the patient characteristics and comorbidities and extensive preoperative laboratory parameters. Methods With examining the records of elderly patients (over 65 years old) with PHF, who were admitted to our emergency department between 2009 and 2020. For evaluation of the survival, we performed Kaplan-Meirer statistical anaylses. A Cox algorithms (uni and multivariate) were applied to recognize factors (including clinical and laboratory parameters) which are associated with survival. Results Sixty-three females and 17 males were included with a mean of 73.5 ± 7.4 years of age. Nineteen (23.83%) patients had decreased after the surgery, with a mean survival of 47.5 ± 32.7 months. There were 61 (76.3%) surviving patients with a mean survival of 67.4 ± 35.4 months. Survival rates in the first 6 months (n: 2 patients), first year (n: 3 patients), and second year (n: 6 patients) after surgery were 97.5%, 96.3%, and 92.3%, respectively. Conclusion The age and preoperative hemoglobin level were independently related with poor survival in patients with PHF. Level of Evidence Level III Retrospective Cohort, Prognosis Study
