Background and purpose - While many other countries implemented strict regulations and restrictions for their citizens during the 1st wave of the Covid-19 pandemic, Sweden maintained a more restrained approach. The Swedish Public Health Agency emphasized individual responsibility and pushed for behavioral changes. With strict lockdown a 77% decrease in ankle fracture incidence has been reported. We investigated whether there was a change in the incidence of ankle fractures seen at 7 selected hospitals during the Covid-19 pandemic 2020.Patients and methods - Data on all ankle fractures treated at 7 selected departments during March 15 through June 15, 2020, and for the same period in the preceding 3 years (2017-2019), was retrieved from the Swedish Fracture Register. The number of fractures during the whole period and subsequent 30-day periods were compared between 2020 and 2017-2019, including subgroup analyses of age and sex.Results - The monthly rate of ankle fractures was reduced by 14% in 2020 (139 fractures) compared with 2017-2019 (161 fractures). Women had a 16% decrease and patients aged > 70 years had a 29% decrease. During the 1st 30-day period, a 26% decrease in fractures was seen.Interpretation - During the 1st wave of the Covid-19 pandemic, a moderate decline in the number of ankle fractures was seen. Women and patients aged > 70 years displayed the greatest reduction. The greatest reduction in incidence of fractures was seen during the 1st 30-day period. This indicates greater adherence to government recommendations regarding social distancing in these subgroups and during the 1st month of the pandemic. Changes in ankle fracture incidence may be a measure of lockdown extent.
背景与目的-在新冠疫情第一波期间，许多其他国家对其公民实施了严格的规定和限制，而瑞典则采取了更为克制的方法。瑞典公共卫生局强调个人责任，并推动行为改变。由于实施了严格的封锁措施，报告称脚踝骨折的发病率下降了 77%。我们调查了在新冠疫情期间（2020 年 3 月 15 日至 6 月 15 日），瑞典 7 家选定医院的脚踝骨折发病率是否发生了变化。
患者和方法-从瑞典骨折登记处检索了 2020 年 3 月 15 日至 6 月 15 日期间和之前 3 年（2017-2019 年）在 7 个选定科室治疗的所有脚踝骨折患者的数据。比较了 2020 年和 2017-2019 年期间整个时期和随后 30 天期间的骨折数量，包括年龄和性别亚组分析。
结果-与 2017-2019 年（161 例）相比，2020 年（139 例）每月脚踝骨折率下降 14%。女性下降 16%，>70 岁患者下降 29%。在第 1 个 30 天期间，骨折减少了 26%。
解释-在新冠疫情第一波期间，脚踝骨折数量适度下降。女性和>70 岁患者的降幅最大。在第 1 个 30 天期间，骨折发生率下降幅度最大。这表明这些亚组和疫情第 1 个月期间，这些人群对政府关于保持社交距离的建议的遵从度更高。脚踝骨折发病率的变化可能是封锁程度的衡量标准。
