Time periods of the Covid-19 pandemic.

Hand and forearm injuries are the most frequent reason for consultations in German emergency departments. Therefore, full recovery has a high social and economic relevance. In this study, data on surgically treated hand injuries in a regional German trauma centre between 01.01.2019 and 31.01.2021 were collected using the new German HandTraumaRegister of the German Society for Hand Surgery. These data were retrospectively analysed and correlated with mobility data of the Bavarian population, the 7-day incidence of Covid-19 infections in Germany and the number of elective hand surgeries. We found that a fall from standing height with consecutive distal radius fracture was the most common injury in women, whereas mechanism of injury and diagnosis were more diverse in men. The populations’ mobility correlated well with the number of accidents, which in turn was reciprocal to the 7-day-incidence of Covid-19 infections. The number of elective hand surgeries expectedly dropped significantly during the state-imposed lockdowns. Knowing that mainly young men and elderly women suffer from hand injuries, tailored prevention measures may be elaborated. In order to reduce socioeconomic burden, care for hand injuries and elective hand surgeries must be guaranteed according to the frequency of their occurrence.手部及前臂损伤是德国急诊科最常见的就诊原因，患者完全康复具有极高的社会与经济价值。本研究依托德国手外科学会（German Society for Hand Surgery）全新推出的德国手部创伤登记系统（HandTraumaRegister），收集了2019年1月1日至2021年1月31日期间，德国某区域创伤中心收治的经手术治疗的手部损伤数据。研究对上述数据开展回顾性分析，并将其与巴伐利亚州人群活动数据、德国新冠病毒（Covid-19）感染7日发病率以及择期手部手术量进行相关性分析。结果显示，女性最常见的损伤为站立位跌倒导致的桡骨远端骨折，而男性的损伤机制与诊断类型则更为多样。人群活动强度与事故发生数量呈显著正相关，而事故数量又与新冠感染7日发病率呈负相关。正如预期，在德国政府实施封禁管控期间，择期手部手术量出现了显著下降。鉴于手部损伤高发人群主要为年轻男性与老年女性，可据此制定针对性的预防措施。为减轻社会经济负担，需根据手部损伤与择期手部手术的发生频次，保障对应的诊疗服务供给。
