The deep transverse metacarpal ligament extends in radio-ulnar direction between the palmar plates of the metacarpo-phalangeal joints of the second through fifth finger rays. Continuing along the path of the palmar plates, the ligament divides the spaces between the fingers at the metacarpo-phalangeal border into functional spaces bordered by the ligamentous apparatus of the metacarpophalangeal joint capsules and filled by blood-vessels, nerves and intrinsic hand muscles. Morphometric examinations of the deep transverse metacarpal ligament indicate a greater strain of the radial components between the index and middle finger in the transverse plane as well as an increased stressing of sagittal fiber plates connecting the extending apparatus with the deep transverse metacarpal ligament via the metacarpophalangeal force nucleus. Palmar, sagittally directed collagen fiber bundles representing a location of initial or recurrent connective tissue proliferation can be histologically demonstrated as a connection between peritendinous and perivascular connective tissue of the palmar interdigital space and the palmar aponeurosis.
掌骨深横韧带在桡尺方向上，位于第二至五指掌指关节掌侧板之间。该韧带沿掌侧板路径延伸，在掌指关节边界处将手指间的间隙分隔成多个功能间隙，这些间隙由掌指关节囊的韧带结构界定，内部充满血管、神经和手部固有肌。对掌骨深横韧带的形态学检查表明，在横断面上，示指和中指之间的桡侧部分应变更大，并且通过掌指力核将伸展装置与掌骨深横韧带相连的矢状纤维板的应力增加。在组织学上，可以证明掌侧、矢状方向的胶原纤维束是掌侧指间间隙的腱周和血管周结缔组织与掌腱膜之间的连接，代表了初始或复发性结缔组织增生的部位。
