Acute DRUJ Instability

  • Brian D. AdamsEmail author


The distal radioulnar joint (DRUJ) is a diarthrodial, synovial articulation that provides the distal link between the radius and ulna and a pivot for pronation-supination. Because its articulation is incongruent, the soft tissues play a substantial role in guiding and restraining the joint. During forearm motion, the DRUJ moves synchronously with the proximal radioulnar joint and thus any injury or deformity involving the radius or ulna can alter the function of both joints. The distal radioulnar and ulnocarpal joints are also anatomically and functionally integrated, so that both are affected by traumatic and arthritic conditions. Because of these interdependences, evaluation and treatment of the DRUJ is challenging. In the treatment of DRUJ instability, proper skeletal alignment is paramount and must be corrected before any soft tissue repair. In addition, the sigmoid notch and ulnar head must be sufficiently competent to allow the ligament restraints to function under normal tension and length. This chapter will discuss the relevant anatomy and pathophysiology of DRUJ instability, along with the rationale and technique for different treatment options.
