For the distal radioulnar joint (DRUJ) to be stable, not only do the articulating surfaces need to be congruent and well aligned but also the capsule and ligaments need to be mechanically and sensorially competent. According to recent investigations, ligaments should not be regarded as simple static structures maintaining articular alignment but as complex arrangements of collagen fibers containing mechanoreceptors, which are able to generate neural reflexes aiming at a more efficient and a more definitive muscular stabilization. By careful planning and meticulous execution of surgical incisions to approach the DRUJ, the nerve endings innervating the capsule and DRUJ ligaments may be safeguarded, thus preserving the proprioceptive function of the joint.
为使桡尺远侧关节（DRUJ）保持稳定，不仅关节面需要相互适配且排列良好，而且关节囊和韧带在机械性能和感觉功能方面也需正常。根据最近的研究，韧带不应被视为维持关节对齐的简单静态结构，而应看作是含有机械感受器的胶原纤维的复杂排列，这些机械感受器能够产生神经反射，以实现更有效、更确切的肌肉稳定。通过精心规划和细致实施用于显露DRUJ的手术切口，可以保护支配关节囊和DRUJ韧带的神经末梢，从而保留关节的本体感觉功能。
