The forearm is composed of the radius, the ulna, the PRUJ, the DRUJ, the triangular fibrocartilage complex, and the IOM, with each structure contributing to forearm stability.
Volar dislocation of the DRUJ is infrequently encountered in practice, with approximately 35 cases reported.
The TFCC is a fibrocartilage-ligament complex composed of multiple structures and plays an important role in stabilizing the DRUJ, transmitting the load between the carpus and ulna, and stabilizing the ulnar aspect of the wrist.[sup][21] The complexity of the TFCC anatomy makes it difficult to diagnose the TFCC injuries accurately.[sup][11] MRI, as a noninvasive examination, has a high resolution of soft tissue and can show the anatomic details of the TFCC.
During a positive piano key sign, the athlete forcefully presses palms into examination table while the clinician observes for increased dorsal-palmer translation of DRUJ, which may suggest instability.
Currently, surgeons assess the stability of the DRUJ manually after fixation of the distal radius to determine which ulnar styloid fractures are associated with instability and require additional intervention.
Cultures of fluid obtained from the DRUJ also came back that day growing S.
With a diagnosis of an irreducible DRUJ dislocation associated with an acute median nerve neuropathy at the wrist and a distal radius fracture, the decision was made to urgently take the patient to the operating room.
There were no cases of DRUJ instability when tested intra-operatively.

The arthritic distal radioulnar joint (DRUJ) is a difficult problem.
INTRODUCTION: Stability of the distal radio ulnar joint (DRUJ) is provided by bony architecture and by soft tissues such as the triangular fibrocartilage complex (TFCC), the joint capsule, and surrounding muscles.
These criteria included less than 10[degrees] residual dorsal angulation (from neutral), less than 2 mm difference in ulnar variance compared to the contralateral side, 1 mm or less articular step off, no dorsal or volar subluxation of the DRUJ on the true lateral radiograph, and no widening of the DRUJ on the PA.
