The distal radioulnar joint.
A phylogenic review shows the DRUJ to be a highly evolved and specialized structure. The diarthrodial joint, in combination with the TFCC, ligament complex, and oblique fibers of the distal interosseous membrane, permit rotation while preserving stability and transmitting the load borne by the radiocarpal joint to both bones of the forearm. Our improved, yet imperfect, understanding of the anatomy, biomechanics, and pathophysiology of the region, abetted by new imaging modalities and wrist arthroscopy, permit more precise diagnosis and thus more rational treatment. The persistent inconsistency of our results belies our imperfect comprehension. Thus humbled, consider Goethe's admonition as a call to further scrutiny and investigation, "Theory and experience are opposed to each other in constant conflict. Only action can reconcile them."
