Five patients suffering from Erb-Duchenne brachial plexus birth palsy were prospectively studied with MRI. A group of 11 healthy children was used as a control to understand the MRI anatomy of the normal growing glenohumeral joint. A hypoplastic and flattened posterior part of the glenoid fossa and a blunt posterior labrum were found in all patients. Four patients had a blunt anterior labrum and a flattened humeral head. Three patients presented with a posterior subluxation of the humeral head. These results suggest that MRI provides a non-ionising and non-invasive method of demonstrating the early abnormalities of the shoulder associated with obstetrical brachial plexus paralysis, which may prompt orthopaedic correction.
对5例患有臂丛神经产瘫（Erb - 杜兴氏型）的患者进行了MRI前瞻性研究。选取11名健康儿童作为对照组，以了解正常生长的盂肱关节的MRI解剖结构。所有患者均发现肩胛盂窝后部发育不全且扁平，以及后盂唇钝圆。4例患者存在前盂唇钝圆和肱骨头扁平。3例患者出现肱骨头后脱位。这些结果表明，MRI提供了一种非电离且非侵入性的方法来显示与产科臂丛神经麻痹相关的肩部早期异常，这可能促使进行骨科矫正。
