The Mallet grading system is a commonly used functional scoring system to assess shoulder abduction/external rotation deficits in children with obstetric brachial plexus palsy. One feature of the Mallet score is that each grade is translated into certain degrees of deficiencies in both shoulder abduction and external rotation. The aim of the current study is to investigate the percentage of children in which the Mallet score could not be applied because of a discrepancy between the deficiency of shoulder abduction and shoulder external rotation. The study group included 50 consecutive unoperated older children (over 5 years of age) with Erb's palsy and deficits in shoulder movements. The Mallet score could be applied in 40 cases (80%). In the remaining 10 cases (20%), the Mallet score could not be applied either because shoulder abduction had a better grade than the grade of shoulder external rotation (n = 7) or vice versa (n = 3). It was concluded that documenting the deficits in shoulder abduction and external rotation are best done separately and this can be accomplished by using other grading systems.
马利特评分系统是一种常用的功能评分系统，用于评估产瘫性臂丛神经麻痹患儿的肩关节外展/外旋功能障碍。马利特评分的一个特点是，每个等级都对应着肩关节外展和外旋一定程度的功能缺陷。本研究的目的是调查因肩关节外展与外旋功能缺陷不一致而无法应用马利特评分的患儿比例。研究组包括50例连续的未接受手术的大龄患儿（5岁以上），患有埃尔布氏麻痹且存在肩部运动功能障碍。马利特评分适用于40例（80%）。在其余10例（20%）中，无法应用马利特评分，原因要么是肩关节外展的等级优于肩关节外旋的等级（n = 7），要么反之（n = 3）。研究得出结论，记录肩关节外展和外旋功能障碍最好分别进行，这可以通过使用其他评分系统来实现。
