The prevalence of known solitary exostosis is around 1-2 % in the general population. Treatment of an exostosis may consist of resection with or without further treatment for deformity. The distal radioulnar joint (DRUJ) acts as the link between radius and ulna at the wrist and is important in the transmission of load. Its anatomic integrity should be respected in surgical procedures or ulnar-s...

Injury to the distal radioulnar joint (DRUJ) is well recognised in association with fractures of the distal radius and ulna. Damage to the articular disc or, more correctly, the triangular fibrocartilage complex of the joint, occurring at the time of injury, is now well recognised as a major cause of persistent symptoms following Colles' fracture.' Isolated injury to the distal radioulnar artic...

PURPOSE Previous in vivo and in vitro studies of forearm supination-pronation suggest that distal radioulnar joint kinematics may be affected by elbow flexion. The primary hypotheses tested by this study were that, in vivo, ulnar variance changes with elbow flexion and forearm rotation, and the arc of forearm rotation changes in relationship to elbow flexion. METHODS Changes in radioulnar kin...

Background: Salvage procedures for distal radioulnar joint (DRUJ) arthritis, like the Darrach or Sauvé-Kapandji (S-K) procedures, often result in extensor tendon ruptures at ulnar stump. Radioulnar instability is considered underlying cause and stump stabilization techniques are employed. This study investigated instability, irritation, effectiveness of following salvage procedures. Methods: Si...

The distal radioulnar joint (DRUJ) is a complex articulation allowing significant rotational and translational motion. Stability of the DRUJ depends on bony contact, intrinsic stabilizers of the triangular fibrocartilage complex, and extrinsic stabilizers of the distal forearm. Understanding the anatomy of this articulation is paramount in clinical decision making for the treatment of disorders...

Instability of the distal ulna is a fairly common problem after acute distal radius fracture (DRF), distal radius malunion, triangular fibrocartilage complex injury, and a host of other types of trauma. We present a new anatomic technique to stabilize the distal ulna with a tendon graft augmented with Mersilene tape, which has been used primarily to treat unidirectional (dorsal or volar) instab...

A rare case of an isolated traumatic palmar dislocation of the distal radioulnar joint is presented. Clinically, there is a loss of pronation and supination. The dislocation was treated using an open reduction, reinsertion of the capsule-ligamentous complex and temporary stabilization using K-wires.

The transradial approach as an access for percutaneous coronary intervention (PCI) has been widely adopted. However, anatomical variations and stenoses may pose significant challenges to the operator. We report a case of successful transradial PCI in a patient with a complete radioulnar loop.
