Fifty cadaver hands were dissected to better delineate the extensor tendon anatomy to the little finger. The extensor digitorum communis was present in 35. Of 15 hands without an extensor digitorum communis, 12 had a junctura present. Three hands lacked both extensor digitorum communis and juncturae. Transfer of the extensor digiti minimi tendon in these hands could cause loss of extension to the little finger. Ten hands had a direct attachment of the extensor digiti minimi tendon on the abductor tubercle. Twenty-two hands had either an attachment of the extensor digiti minimi on the abductor tubercle, an unbalanced ulnar slip of the extensor digiti minimi, or both, anatomic factors that could--in the event of ulnar nerve compression or laceration--cause Wartenberg's sign. Twenty-eight hands did not have an anatomic variant of the extensor that could cause ulnar deviation of the little finger.
解剖了50具尸体的手，以更好地描绘小指的伸肌腱解剖结构。35只手中存在指总伸肌。在15只没有指总伸肌的手中，12只存在腱间结合。3只手既没有指总伸肌也没有腱间结合。在这些手中转移小指伸肌腱可能导致小指伸展功能丧失。10只手的小指伸肌腱直接附着于外展结节。22只手的小指伸肌腱要么附着于外展结节，要么小指伸肌尺侧束不平衡，或者两者皆有，这些解剖学因素在尺神经受压或撕裂的情况下可能导致沃滕伯格征。28只手没有可能导致小指尺偏的伸肌解剖变异。
