BACKGROUND Instability of the distal radioulnar joint (DRUJ) is a complication that can occur following distal radius fracture or malunion. We have observed that residual radial translation of the distal radius, relative to the radial shaft, may be a causal factor of DRUJ instability, even once the traditional radiographic parameters (volar tilt, radial inclination, and ulnar variance) have bee...

OBJECTIVE To report arthroscopic findings in dogs with severe elbow incongruity combined with fragmented medial coronoid process (FCP) and compare these findings in normal joints and congruent joints affected by FCP. STUDY DESIGN Clinical study. ANIMALS Dogs with elbow lameness (n = 40) and purpose bred dogs (5; controls). MATERIALS AND METHODS Arthroscopic features of 32 severely incongr...

The purpose of this article is to describe a technique of restoring stability or congruency to the distal radioulnar joint (DRUJ) by osteoplasty or osteotomy of the sigmoid notch, where abnormalities in the osseous anatomy have resulted in DRUJ instability. This technique addresses the osseous cause to DRUJ instability and avoids the need for complex soft tissue procedures to treat chronic vola...

During the last two decades, increased knowledge of functional anatomy and pathophysiology of the triangular fibrocartilage complex (TFCC) have contributed to a change in surgeons' perspective toward it. The earlier concept of the TFCC as the "hammock" structure of the ulnar carpus has updated to the "iceberg" concept, whereby the much larger "submerged" part represents the foveal insertions of...

BACKGROUND Volar instability of the distal radioulnar joint (DRUJ) is uncommon, and there is little written about it. The purpose of this study is to describe a new procedure to treat volar DRUJ instability and to present the outcomes of patients who received this unique surgical repair at a minimum of 1 year follow-up. METHODS We performed a retrospective case series of 6 consecutive patient...

A 13-year-old girl occasionally felt pain on the ulnar side of her right wrist before her right forearm abruptly locked in the pronated position while playing basketball. She had no pain or swelling after the injury; and after a month of therapy, she was seen at our hospital. On physical examination, the right forearm was locked in 70” pronation. When supination was attempted, the patient felt ...
