We present our approach to gleno-humeral joint deformities as sequelae from severe upper obstetric brachial plexus palsy. In 50 consecutive children with severe medial rotation contracture of the shoulder after obstetric brachial plexus palsy, we used magnetic resonance imaging to evaluate joint incongruence and dysplasia; showing frequently various deformities of the glenoid, the humeral head and pathologic changes in their relationship. The most severe deformity is true glenohumeral dysplasia. These diagnostic findings might influence our choice and technical details within surgical procedures. We actually evaluate image processing tools (segmentation software) for a better understanding of changes in anatomical structures responsible for this multifactorial joint deformity, limiting lateral and/or medial rotation of the glenohumeral joint in children with obstetric brachial plexus palsy.
我们介绍了针对严重产伤性臂丛神经麻痹后遗症所致的盂肱关节畸形的治疗方法。在50例连续的产伤性臂丛神经麻痹后出现严重肩部内旋挛缩的儿童中，我们使用磁共振成像来评估关节不匹配和发育异常；结果显示，盂肱关节常常存在各种畸形，包括肩胛盂、肱骨头的畸形以及它们之间关系的病理变化。最严重的畸形是真性盂肱关节发育异常。这些诊断结果可能会影响我们在手术过程中的选择和技术细节。我们实际上正在评估图像处理工具（分割软件），以便更好地了解导致这种多因素关节畸形的解剖结构变化，这种畸形会限制产伤性臂丛神经麻痹患儿盂肱关节的外旋和/或内旋。
