Abstract:
Mortality of patients after osteosynthesis of proximal humeral fractures (PHF) has been poorly studied in contrast to fractures of the proximal femur.
Objective:
To evaluate the mortality of older patients with PHF undergoing surgical treatment.
Methods:
Retrospective study of patients undergoing surgical treatment PHF between 2009-2019. Demographic data, Neer classification, and mortality of this cohort of patients were evaluated. Non-categorical variables were tested using the Kolmogorov-Smirnov test. The unpaired t-test (parametric variables) was used. Categorical variables were tested by Fisher's exact test. A Kaplan-Meier mortality curve was constructed.
Results:
59 patients were evaluated. There was a predominance of females in the sixth decade of life. The most prevalent fractures were Neer's type III. The highest mortality occurred in the first 4 years after surgery (4.1 + 3.2 years). The only comorbidity capable of changing the survival curve was DM (p = 0.03) Conclusion: Overall mortality was 11.3%. The highest mortality occurred in the first 4 years of follow-up. Diabetic patients evolve with earlier mortality and have 7 times more chance of death. Level of Evidence III, Retrospective Study.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
