Objectives This study examines the incidence of ankle injuries and identifies ankle injury risk among contemporary preprofessional dancers. Methods A total of 91 first-year contemporary preprofessional dancers were prospectively followed during one academic year. Self-reported ankle injuries, assessed with the Oslo Sports Trauma Research Centre questionnaire, were categorised as all complaint ankle injuries, substantial ankle injuries or time-loss ankle injuries. In addition, ankle injuries leading to medical attention were included. Regression analyses were used to determine the association between potential risk factors (dancer characteristics, history of ankle injury in the previous year, ankle range of motion and dorsiflexion) and ankle injuries. Results The 1-year ankle injury incidence proportion was 18.7% (n=17), 8.8% (n=8), 15.4% (n=14) and 7.7% (n=7), respectively, for all complaint ankle injuries, ankle injuries requiring medical attention, time-loss injuries and substantial injuries. Being male (OR=0.27; 95% CI 0.09 to 0.75) and being a student of the Bachelors in Dance and Education (OR=0.27; 95% CI 0.08 to 0.97) were univariately associated with a lower risk of an ankle injury. Conclusion Almost 20% of first-year preprofessional dancers reported an ankle injury, with more than 80% of the dancers reporting that their injury leads to dance time loss. Males and students of the bachelors in dance and education were at lower risk of ankle injuries. As ankle injuries are common among dancers, studies with larger sample sizes, a more heterogeneous population (eg, different dance styles) and longer follow-up periods are necessary to evaluate the impact of ankle injuries in further detail. Data are available on reasonable request.

踝关节损伤风险的发生率和预测：一项针对 91 名当代职业舞蹈演员的前瞻性队列研究

目的 本研究检查了脚踝受伤的发生率，并确定了当代职业舞蹈演员的脚踝受伤风险。方法 在一个学年中前瞻性地跟踪了 91 名一年级的当代专业舞蹈演员。使用奥斯陆运动创伤研究中心问卷评估的自我报告的脚踝受伤被归类为所有抱怨脚踝受伤、严重脚踝受伤或时间损失脚踝受伤。此外，还包括导致就医的踝关节损伤。回归分析用于确定潜在危险因素（舞者特征、前一年踝关节损伤史、踝关节活动度和背屈）与踝关节损伤之间的关联。结果 1年踝关节损伤发生率分别为18.7%（n=17）、8.8%（n=8）、15。分别为 4% (n=14) 和 7.7% (n=7) 的所有主诉脚踝受伤、需要医疗护理的脚踝受伤、误工伤和重伤。男性（OR=0.27；95% CI 0.09 至 0.75）和舞蹈与教育学士学位的学生（OR=0.27；95% CI 0.08 至 0.97）单因素与较低的踝关节损伤风险相关。结论 几乎 20% 的第一年专业舞者报告了脚踝受伤，超过 80% 的舞者报告说他们的受伤导致舞蹈时间损失。男性和舞蹈和教育学士的学生脚踝受伤的风险较低。由于脚踝受伤在舞者中很常见，因此样本量更大的研究、更异质的人群（例如，不同的舞蹈风格）和更长的随访期对于更详细地评估脚踝受伤的影响是必要的。可根据合理要求提供数据。
