一种新的臂丛病变类型被定义为在经典类型的基础上增加，即上型(Duchenne Erb)、下型(DeJerine Klumpke)和全型。这种新的类型是中间性麻痹。病变是部分累及神经丛，主要累及C7，累及上丛或下丛。通过在手术中和身体上的观察，三种不同的机制被认为是导致三种不同类型病变的原因。向下牵引的创伤主要累及上丛。外展损伤首先累及下神经丛，而创伤性力量从前向后首先累及C7脊神经，C7脊神经处于前位，与其他神经根相比倾斜程度较小。脐带撕脱或破裂是可能的。观察33例。
A new type of brachial plexus lesion has been defined to be added to the classical types, i.e. the upper (Duchenne Erb), the lower (Dejerine Klumpke) and the total type. This new type is the intermediate palsy. The lesion is a partial involvement of the plexus, the predominant lesion of which involves C7 with a variable involvement of the upper or lower plexus. By observations during operation, and in cadavers, three different mechanisms are considered responsible for the three different types of lesion. A trauma with downwards traction principally involves the upper plexus. Trauma in abduction first involves the lower plexus while a traumatic force acting from an anterior to a posterior direction involves firstly and predominantly the C7 spinal nerve which is in an anterior position and less oblique than the other roots. Avulsion from the cord or rupture are possible. 33 cases have been observed.
