The aponeurosis of the common extensor tendons is connected by intertendinous connections proximal to the metacarpophalangeal joints. These fibers are responsible for tenodesis effects in case of maximal finger extension and flexion and by this means they diminish the function of the other metacarpophalangeal joints. This mechanism can be described as the Quadriga-Syndrome of the extensor apparatus. These connecting structures also help to stabilize the transverse metacarpophalangeal arch and the position of the extensor tendons over the metacarpal heads. Cadaver dissections as well as operative findings have shown that there exists a superficial transverse intermetacarpal ligament, which connects the metacarpal heads in the area of its neck.
常见伸肌腱的腱膜在掌指关节近端通过腱间连接相连。这些纤维在手指最大程度伸展和屈曲时负责产生腱固定效应，通过这种方式，它们会削弱其他掌指关节的功能。这种机制可被描述为伸肌装置的“四联征”。这些连接结构也有助于稳定掌指横弓以及伸肌腱在掌骨头上方的位置。尸体解剖以及手术发现表明，存在一条浅表的掌骨间横韧带，它在掌骨颈部区域连接掌骨头。
