Aim To describe the demographics, frequency, location, imaging modality and clinician-identified factors of rib stress injury in a cohort of elite rowers over the Rio Olympiad (2012–2016). Methods Analysis of prospectively recorded medical records for the Australian Rowing Team in 2013–2015 and the combined Australian Rowing Team and Olympic Shadow Squad in 2016, examining all rib stress injuries. Results 19 rib stress injuries (12 reactions and 7 fractures) were identified among a cohort of 151 athletes and included 12 female and 7 male cases, 11 open weight, 8 lightweight, 12 scull and 7 sweep cases. The most common locations of injury identified by imaging, were the mid-axillary line and rib 6. Period prevalence varied from 4% to 15.4% and incidence ranged from 0.27 to 0.13 per 1000 athlete days. There were no significant differences in prevalence by sex, sweep versus scull or weight class. There was a statistically significant increase in incidence in the pre-Olympic year (2015, p<0.001). MRI was the most commonly used modality for diagnosis. Stress fracture resulted in median 69 (IQR 56–157) and bone stress reaction resulted in 57 (IQR 45–78) days lost to full on water training. Conclusions In our 4-year report of rib stress injury in elite rowing athletes, period prevalence was consistent with previous reports and time lost (median ~10 weeks) was greater than previously published literature. Rib stress injury limits training and performance in elite rowers and MRI should be considered as a first line investigation.

2012-2016 年(里约)奥林匹克运动会中的肋骨应力损伤:对 151 名澳大利亚赛艇队运动员进行 88773 个运动员日的队列研究

目的 描述 2012-2016 年里约奥运会(2012-2016)精英赛艇运动员中肋骨应力损伤的人口统计学、频率、位置、成像方式和临床医生确定的因素。方法 分析 2013-2015 年澳大利亚赛艇队以及 2016 年澳大利亚赛艇队和奥林匹克影子队联合队的前瞻性记录病历,检查所有肋骨应力损伤。结果 151名运动员共发生肋骨应力性损伤19例(12例反应,7例骨折),其中女12例,男7例,空腹11例,轻量8例,双桨12例,横扫7例。通过成像确定的最常见的损伤部位是腋中线和第 6 肋骨。经期患病率从 4% 到 15.4% 不等,发生率从每 1000 个运动员日 0.27 到 0.13 不等。性别、横扫与双桨或体重等级的流行率没有显着差异。奥运前年的发病率在统计学上显着增加(2015 年,p<0.001)。MRI是最常用的诊断方式。应力性骨折导致中位数为 69 (IQR 56-157),骨应力反应导致 57 (IQR 45-78) 天在水上训练中失去完全。结论 在我们关于优秀赛艇运动员肋骨应力损伤的 4 年报告中,经期患病率与之前的报告一致,时间损失(中位数~10 周)大于之前发表的文献。肋骨应力损伤限制了精英赛艇运动员的训练和表现,MRI 应被视为一线调查。奥运前年的发病率在统计学上显着增加(2015 年,p<0.001)。MRI是最常用的诊断方式。应力性骨折导致中位数为 69 (IQR 56-157),骨应力反应导致 57 (IQR 45-78) 天在水上训练中失去完全。结论 在我们关于优秀赛艇运动员肋骨应力损伤的 4 年报告中,经期患病率与之前的报告一致,时间损失(中位数~10 周)大于之前发表的文献。肋骨应力损伤限制了精英赛艇运动员的训练和表现,MRI 应被视为一线调查。奥运前年的发病率在统计学上显着增加(2015 年,p<0.001)。MRI是最常用的诊断方式。应力性骨折导致中位数为 69 (IQR 56-157),骨应力反应导致 57 (IQR 45-78) 天在水上训练中失去完全。结论 在我们关于优秀赛艇运动员肋骨应力损伤的 4 年报告中,经期患病率与之前的报告一致,时间损失(中位数~10 周)大于之前发表的文献。肋骨应力损伤限制了精英赛艇运动员的训练和表现,MRI 应被视为一线调查。应力性骨折导致中位数为 69 (IQR 56-157),骨应力反应导致 57 (IQR 45-78) 天在水上训练中失去完全。结论 在我们关于优秀赛艇运动员肋骨应力损伤的 4 年报告中,经期患病率与之前的报告一致,时间损失(中位数~10 周)大于之前发表的文献。肋骨应力损伤限制了精英赛艇运动员的训练和表现,MRI 应被视为一线调查。应力性骨折导致中位数为 69 (IQR 56–157),骨应力反应导致 57 (IQR 45–78) 天在水上训练中失去完全。结论在我们关于优秀赛艇运动员肋骨应力损伤的 4 年报告中,经期患病率与之前的报告一致,时间损失(中位数~10 周)大于之前发表的文献。肋骨应力损伤限制了精英赛艇运动员的训练和表现,MRI 应被视为一线调查。
