BACKGROUND: Identifying radial head fractures as fragility fractures may improve case-findings for osteoporosis and thus be an indicator other fragility fractures. MATERIALS AND METHODS: Thirty-five women aged ≥ 50 years with a radial head fracture and 57 controls were retrospectively selected and matched for age in strata of 5 years. Peripheral bone mineral density (BMD) measurement was performed at the calcaneus. A T score of less than -2.7 was considered osteoporosis. If the T value was between -1.4 and -2.7, an additional dual energy X-ray (DXA) scan was performed. RESULTS: The patients were a median age of 60 years compared with 58 years for the control patients (P = .33). The mean T score of the patients was -1.8 (standard deviation [SD], 1.0; range, -2.2 to -0.3) compared with -1.2 (SD, 1.2; range, -4.0 to 1.3) for the control patients (P = .04). Osteoporosis was diagnosed in 11 patients and in 5 control patients. The patients had an increased risk of osteoporosis compared with the control patients (odds ratio, 3.4; P = .027). CONCLUSIONS: This study confirms that radial head fractures in women aged ≥ 50 years are potentially osteoporotic fractures. Offering these patients a BMD measurement may prevent future osteoporotic fractures, such as hip and spine fractures.
