Rethinking Conservative Treatment of Humeral Diaphyseal Fractures in Elderly Patients With Dementia.

Objectives: To assess outcomes and complications of conservatively managed humeral diaphyseal fractures in elderly patients, with an emphasis on the subgroup diagnosed with dementia.
Design: Retrospective.
Setting: Upper extremity surgery unit at an academic Level I trauma center.
Patients/participants: Consecutive patients 65 years of age and older who were managed conservatively for humeral diaphyseal fractures between 2007 and 2015.
Intervention: Conservatively managed humeral diaphyseal fractures.
Main Outcome Measurements: Complications and radiographic outcomes.
Results: One-hundred twenty-four patients who were conservatively managed for humeral diaphyseal fractures were identified. Their mean age was 77 (65-92) years, 36 (30%) of them were male and 88 (70%) were female. Fifty-seven (46%) patients experienced complications associated with their treatment, and 33 (27%) patients were eventually treated surgically. Seventeen (14%) patients were diagnosed with dementia. This subgroup had 64% fracture-related complications, and all of them were operated (P-value <0.01 compared with age-matched patients among the other 107 participants in the study).
Conclusion: Conservative management of humeral diaphyseal fractures seems to be associated with greater morbidity in elderly patients, especially in those diagnosed with dementia. Therefore, early surgical treatment should be considered.
