Medical-attention injuries were reported to and recorded by onsite physiotherapists between January 2018 and December 2021. Time-loss injuries were any injury that prevented a dancer from taking a full part in all dance-related activities for &gt;1 day . Injuries were classified using the OSICS-10.1 system. Injury incidence rates (IIRs; injuries\/1000 h), severity, recurrence, and burden were calculated. <\/jats:p><jats:p> RESULTS: Nine hundred and fifty-three medical-attention injuries were recorded in 72 (98%) dancers at an IIR of 2.79\/1000 h (95% confidence interval [CI], 2.62-2.98). 706 were time-loss injuries, which were reported in 70 dancers at an IIR of 2.07\/1000 h (95% CI: 1.92, 2.23). Overuse injuries represented 53% of medical-attention injuries. The most frequently injured body area and tissue\/pathology were thoracic facet joint (n = 63\/953, 7%) and ankle synovitis\/impingement (n = 62\/953, 6%). Bone stress injuries (BSIs) were the most severe with the highest median time loss (135 days, interquartile range [IQR] 181) followed by fractures (72.5 days, IQR 132). The injuries with the highest burden were tibial BSIs (13 days lost\/1000 h; 95% CI: 13, 14). Jumping and lifting were the most frequently reported injury mechanisms. <\/jats:p><jats:p> CONCLUSION: Almost all dancers required medical attention for at least one injury during the surveillance period. Approximately 74% of injuries resulted in time loss. BSIs and ankle synovitis\/impingement were of high burden, and a high proportion of BSIs were recurrent.
