Outcomes of operative and nonoperative treatment of 3- and 4-part proximal humeral fractures in elderly: a 10-year retrospective cohort study.

PURPOSE: Despite a rising incidence in proximal humeral fractures, there is still no evidence for the best treatment option, especially for elderly patients. The aim of this retrospective cohort study was to evaluate health-related quality of life (HRQoL), functional outcome, pain and social participation in elderly patients, after operative and nonoperative treatment of displaced 3- and 4-part proximal humeral fractures.

METHODS: 150 patients aged ≥ 65, treated for a displaced 3- or 4-part proximal humeral fracture between 2004 and 2014, were invited to participate. Eventually 91 patients (61%) participated, of which 32 non-operatively treated patients were matched to 32 of the 59 operatively treated patients by propensity score matching. The EQ-5D, DASH, VAS for pain and WHODAS 2.0 Participation in Society domain were administered. Complications and reinterventions were registered.

RESULTS: No significant difference was found between the two treatment groups in HRQoL (p = 0.43), function (p = 0.78) and pain (p = 0.19). A trend toward better social participation in the operative group (p = 0.09) was found. More complications and reinterventions occurred in the operative group than the nonoperative group, with 9 versus 5 complications (p = 0.37) and 8 versus 2 reinterventions (p = 0.08).

CONCLUSIONS: In this study, we found no evidence of a difference in HRQoL, functional outcome or pain 1-10 years after operative or nonoperative treatment in patients of 65 and older with a displaced 3- or 4-part humeral fracture. Operatively treated patients showed a trend toward better social participation but also higher reintervention rates.
