One hundred eighty-one dissected hands were examined to study the pattern of extensor tendons on the dorsum of the hand. Extensor digitorum often had multiple tendons for the middle and ring fingers. Its contribution to the little finger was usually by a bifurcating tendon common with that of the ring finger. The index finger always received a single tendon. Intertendinous connections between the various tendons of the extensor digitorum were variable but were most frequent between ring and middle fingers. Extensor indicis had one tendon in most of the specimens and it was always on the ulnar side of the extensor digitorum tendon. This remained true even when there were multiple tendons. Extensor digiti minimi had two tendons in most cases. It was always linked to extensor digitorum either by receiving one or part of its tendon or by an intertendinous connection. Two accessory muscles were seen, one was extensor indicis brevis replacing the proper muscle. The other, the extensor medii brevis, was distributed to the middle finger.
对181只解剖后的手进行了检查，以研究手背伸肌腱的形态。指伸肌的中、环指通常有多条肌腱。它对小指的作用通常是通过与环指共用的一条分叉肌腱来实现的。示指总是接受一条单一的肌腱。指伸肌各肌腱之间的腱间连接情况不一，但在环指和中指之间最为常见。在大多数标本中，示指伸肌有一条肌腱，且总是位于指伸肌腱的尺侧。即使存在多条肌腱，情况依然如此。在大多数情况下，小指伸肌有两条肌腱。它总是通过接受指伸肌的一条或部分肌腱，或者通过腱间连接与指伸肌相连。发现了两块副肌，一块是代替固有肌的示指短伸肌。另一块是分布于中指的中指短伸肌。
