Predictors of Management of Distal Radius Fractures in Patients Aged >65 Years.

Abstract

Treatment of distal radius fractures (DRFs) in patients aged >65 years is controversial. The purpose of this study was to identify what patient and fracture characteristics may influence the decision to pursue surgical versus nonsurgical treatment in patients aged >65 years sustaining a DRF. We queried our institutional DRF database for patients aged >65 years who presented to a single academic, tertiary center hand clinic over a 5-year period. In all, 164 patients treated operatively were identified, and 162 patients treated nonoperatively during the same time period were selected for comparison (total N = 326). Demographic variables and fracture-specific variables were recorded. Patient and fracture characteristics between the groups were compared to determine which variables were associated with each treatment modality (operative or nonoperative). The average age in our cohort was 72 (SD: 11) years, and 274 patients (67%) were women. The average Charlson Comorbidity Index (CCI) was 4.1 (SD: 2.1). The CCI is a validated tool that predicts 1-year mortality based on patient age and a list of 22 weighted comorbidities. Factors associated with operative treatment in our population were largely related to the severity of the injury and included increasing dorsal tilt (odds ratio [OR], 1.09; 95% confidence interval [CI], 1.05-1.12; <i>P</i> < .001) and AO Classification type C fractures (OR, 5.42; 95% CI, 2.35-11.61; <i>P</i> < .001). Increasing CCI was the only factor independently associated with nonoperative management (OR, 0.84; 95% CI, 0.72-0.997; <i>P</i> = .046). Fracture severity is a strong driver in the decision to pursue operative management in patients aged >65 years, whereas increasing CCI predicts nonoperative treatment.
