BACKGROUND Subluxation of ulna in distal radioulnar joint disorders causes pain on motion, loss of grip strength, and a restriction of forearm rotation. Several procedures have been described to salvage DRUJ disorders including the Darrach procedure, the matched distal ulnar resection, the hemiresection interposition arthroplasty (Bowers procedure) and the Sauve-Kapandji (S-K) procedure. All th...

Background: Osteochondritis dissecans (OCD) of the capitellum is common in throwing athletes and believed to result from repetitive overloading on radiocapitellar (RC) joint, although cause mechanism remain unclear. The torsional forces (moments) generated by triceps during elbow extension pull only ulna; therefore, radial head moves passively across effectively “dragged along” ulna. Any laxity...

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 contai...
