The technical simplicity of the Darrach procedure may explain why it has been so popular. Excising the distal ulna, however, may have potentially undesired consequences to the biomechanics in two areas: the distal radioulnar and the ulno-carpal joints. These conjointly define the radio-ulno-carpal joint (RUCJ). The RUCJ is not a small and irrelevant articulation that can be removed without possibly paying a functional penalty. It is an important link of the antebrachial frame that provides stability to the distal forearm and the carpus. This article revisits the mechanisms by which some ligaments and muscles ensure that all forces about and within the RUCJ are dealt with efficiently.
