Identifying radial head fractures as fragility fractures may improve case-findings for osteoporosis and thus be an indicator other fragility fractures.
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.
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).
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.
将桡骨小头骨折视为脆性骨折可以提高骨质疏松症的检出率，从而成为其他脆性骨折的一个指标。
回顾性选择了 35 名年龄≥50 岁的桡骨小头骨折女性患者和 57 名年龄匹配的对照者，按 5 年为一个年龄段分层。在跟骨处进行外周骨矿物质密度（BMD）测量。T 值小于-2.7 被认为是骨质疏松症。如果 T 值在-1.4 到-2.7 之间，则进行额外的双能 X 射线（DXA）扫描。
患者的平均年龄为 60 岁，而对照组患者的平均年龄为 58 岁（P=.33）。患者的平均 T 值为-1.8（标准差[SD]，1.0；范围，-2.2 到-0.3），而对照组患者的平均 T 值为-1.2（SD，1.2；范围，-4.0 到 1.3）（P=.04）。11 名患者和 5 名对照者被诊断为骨质疏松症。与对照组相比，患者发生骨质疏松症的风险增加（比值比，3.4；P=.027）。
本研究证实，50 岁以上女性的桡骨小头骨折可能是骨质疏松性骨折。为这些患者提供 BMD 测量可能会预防未来的骨质疏松性骨折，如髋部和脊柱骨折。
