Left-handedness was reported to be a risk factor for accident-related injuries, head injuries, traumatic brain injuries, sport-related injuries, and bone breaks and fractures. As decreased bone mineral density is a good marker of bone fractures, the femoral bone mineral densities of normal left-handed university students were compared with those of right-handed students. Hand preference of 66 men and 47 women was assessed using the Edinburgh Handedness Inventory. Measures of bone mineral density with a Hologic QDR-4500W (S/N 48403) densitometer showed bone mineral densities of both right and left proximal femur regions were higher in right-handed than in left-handed students. These results are consistent with the claim that left-handed participants had higher trauma and injury risk. Also, these results may explain the sex-related differences by handedness for susceptibility in accident-related injuries such as bone fractures.
有报道称，左撇子是与事故相关的伤害、头部受伤、创伤性脑损伤、运动相关损伤以及骨折和骨折的风险因素。由于骨密度降低是骨折的良好标志物，因此比较了正常左撇子大学生和右撇子大学生的股骨骨密度。使用爱丁堡手性量表评估了 66 名男性和 47 名女性的手性偏好。使用 Hologic QDR-4500W（S/N 48403）密度计进行的骨矿物质密度测量显示，右撇子学生的右侧和左侧股骨近端区域的骨矿物质密度均高于左撇子学生。这些结果与左撇子参与者受伤和受伤风险较高的说法一致。此外，这些结果可能通过与事故相关的损伤（如骨折）的易感性的手性解释了性别相关的差异。
