We have determined the frequency and significance of finger-nail splinter haemorrhages in 220 patients over the age of 65 years admitted to acute geriatric wards. Splinter haemorrhages were found in 35 (16%) patients. Splinters are less common in the elderly than in younger people. They are associated with the use of walking aids; trauma to the nails seems to be the main causative factor. We found no association between splinter haemorrhages and specific medical disorders, bacteraemia or senile purpura. Splinter haemorrhages are an unhelpful physical sign in the elderly.
我们已确定了220名65岁以上入住急性老年病房患者指甲裂片样出血的发生率及意义。35名（16%）患者发现有裂片样出血。裂片样出血在老年人中比年轻人中少见。它们与使用助行器有关；指甲受到外伤似乎是主要致病因素。我们未发现裂片样出血与特定的内科疾病、菌血症或老年性紫癜之间存在关联。裂片样出血对老年人来说是一项无诊断价值的体征。
