Ligamentotaxis is the principle of molding fracture fragments into alignment as a result of tension applied across a fracture by the surrounding intact soft tissues. Uniplanar ligamentotaxis obtained by longitudinal traction does not always restore palmar tilt to the distal radius. Multiplanar ligamentotaxis extends the principle of uniplanar ligamentotaxis to include translation of the hand in the dorsal-palmar and the radial-ulnar planes to effect appositional and tilting alignment of the distal fragment(s) of a fractured radius. Use of an external fixator that allows adjustments in multiple planes helps restore anatomic alignment and maintain fracture reduction during healing.
韧带整复术是指通过周围完整软组织对骨折施加张力,从而使骨折碎片塑形并对齐的原理。通过纵向牵引获得的单平面韧带整复术并不总能恢复桡骨远端的掌倾角。多平面韧带整复术扩展了单平面韧带整复术的原理,将手部在背掌侧和桡尺侧平面的平移纳入其中,以实现桡骨骨折远端碎片的对位和倾斜对齐。使用可在多个平面进行调整的外固定器有助于恢复解剖对齐,并在愈合过程中维持骨折复位。
