Current treatment of distal radioulnar joint dislocation / 中华创伤骨科杂志

ABSTRACT

The distal radioulnar joint (DRUJ) is one of the most important joints connecting hand and forearm,playing an important role in maintaining normal rotation of the hand and forearm and stability of the wrist.Serious DRUJ dislocation can lead to functional limitation of the forearm and wrist.DRUJ displacement is not uncommon clinically,but often missed.It is usually associated with a distal radioulnar fracture,with an incidence ranging from 10％ to 19％.Without correct and effective diagnosis and treatment,it will lead to chronic pain,dysfunction and other complications.There are various treatments for DRUJ displacement,like initiative splint fixation,percutaneous fixation with kirschner wire,soft tissue reconstruction,joint fusion and joint replacement at the end-stage,and arthroscopic techniques as well which are increasingly popular in recent years.All these treatments ease the patients' pain to a certain extent,but also bring about complications of different severities.Currently,reconstruction of the DRUJ stability using elastic suspension system may be a new treatment alternative in the future because it has gradually attracted the attention from experts.
