■先前对运动人群的研究表明,没有症状或已知病理的个体可能存在异常磁共振成像(MRI)发现。将这种理解扩展到芭蕾舞,特别是关于脚和脚踝,指导给舞者的医疗建议很重要。
■评估无症状芭蕾舞演员的足踝MRI扫描,重点是骨髓水肿和后踝关节,并调查这些MRI结果是否会在1年内出现症状。
■案例系列;证据级别,4.
■总共,31名健康舞者(62英尺/脚踝;15名男性和16名女性;年龄,26.5±4.3年),从一家精英专业芭蕾舞团招募了全部能力跳舞的人。使用3TMRI获得了脚和脚踝的正交3平面短tau反转恢复成像,并由2名肌肉骨骼放射科医生使用标准化评估表审查了图像。记录了公司的伤害,并评估了MRI阳性结果与随后12个月内需要医疗护理的任何伤害的相关性。
■在62英尺和脚踝中,共有51(82%)的骨髓水肿面积≥1。骨髓水肿最常见的位置是距骨(n=41;66%),其次是第一meta骨(n=14;23%)。在5(8%)和8(13%)脚踝中观察到三角和Stieda过程,分别。其中,2μs三角菌显示骨髓水肿。在前、后足骨膜关节和距下关节中观察到48%的液体,63%,63%的关节,分别。观察到足部和踝关节肌腱周围有液体,最普遍的是长屈屈肌腱(n=13;21%)。两名在MRI上有阳性发现的舞者随后在接下来的12个月中出现了症状。
■在无症状的专业芭蕾舞演员的脚和踝关节中,MRI阳性结果很常见。大多数在12个月内不会导致需要医疗护理的症状发展。在建议修改活动或进一步干预之前,需要根据舞者的临床表现仔细解释MRI结果。
UNASSIGNED: Previous research in sport populations has demonstrated that abnormal magnetic resonance imaging (MRI) findings may be present in individuals without symptoms or known pathology. Extending this understanding to ballet, particularly in relation to the foot and ankle, is important to guide medical advice given to dancers.
UNASSIGNED: To assess foot and ankle MRI scans in asymptomatic ballet dancers focusing on bone marrow edema and the posterior ankle and to investigate whether these MRI findings would become symptomatic within 1 year.
UNASSIGNED: Case series; Level of evidence, 4.
UNASSIGNED: In total, 31 healthy dancers (62 feet/ankles; 15 male and 16 female; age, 26.5 ± 4.3 years) who were dancing in full capacity were recruited from an elite professional ballet company. Orthogonal 3-plane short tau inversion recovery imaging of both feet and ankles was obtained using 3T MRI and the images were reviewed using a standardized evaluation form by 2 musculoskeletal radiologists. Injuries in the company were recorded and positive MRI findings were assessed for correlation with any injuries requiring medical attention during the subsequent 12 months.
UNASSIGNED: A total of 51 (82%) of the 62 feet and ankles had ≥1 area of bone marrow edema. The most common locations of bone marrow edema were the talus (n = 41; 66%), followed by first metatarsal (n = 14; 23%). Os trigonum and Stieda process were seen in 5 (8%) and 8 (13%) ankles, respectively. Among them, 2 os trigona showed bone marrow edema. Fluid in the anterior and posterior talocrural joints and the subtalar joint was observed in 48%, 63%, and 63% of these joints, respectively. Fluid around foot and ankle tendons was observed, with the most prevalent being the flexor hallucis longus tendon (n = 13; 21%). Two dancers who had positive findings on their MRI subsequently developed symptoms during the next 12 months.
UNASSIGNED: Positive MRI findings are commonplace in the foot and ankle of asymptomatic professional ballet dancers. The majority do not result in the development of symptoms requiring medical attention within 12 months. Careful interpretation of MRI findings with the dancer\'s clinical picture is required before recommending activity modification or further intervention.
