Distal radioulnar arthroplasty is an attractive solution for treating various pathological conditions of the distal radioulnar joint because it allows restoration of stability, load transmission and function. The main indications are: radioulnar impingement after partial or complete resection of the distal ulna; and degenerative, inflammatory or post-traumatic arthritis of the distal radioulnar...

HYPOTHESIS Using Lister's tubercle and the ulnar styloid as landmarks, accurate localization of the distal radioulnar joint can be achieved without the need for an image-guided approach. METHODS Cadaveric dissection of 16 upper extremities was performed to measure the relationships between the ulnar styloid, Lister's tubercle, and the distal radioulnar joint. In each specimen, the location of...

INTRODUCTION The distal radioulnar joint is of paramount importance for the proper function of the upper extremity. There is a wide variety of procedures for the treatment of its advanced pathology but none of them is capable of providing a stable load-bearing joint. CLINICAL CASE We present the case of a 54 year old man who was treated by a semiconstrained bipolar distal radioulnar joint art...

One of the more difficult problems in wrist surgery is an injury to the ulna side of the wrist associated with a distal radius fracture. When should these be treated acutely and when do they resolve without the need for surgical intervention? The long term disability due to DRUJ problems is significant and includes pain, instability, loss of motion or any combination of the above. Importantly n...

BACKGROUND To analyze clinical outcomes after anatomical reconstruction of distal radioulnar ligaments in patients with chronic post-traumatic instability of the distal radioulnar joint. METHODS Anatomical reconstruction was performed in 16 patients with subluxation or dynamic instability of distal radioulnar joint following trauma. Osteotomy was performed simultaneously in 10 patients with r...

BACKGROUND The radioulnar carpal joint is critical for hand and wrist function. Radioulnar deviation indicates distal radioulnar joint flexibility and reflects the structure and function of the carpal bones, ulna, radius and ligaments. The present study examined whether radioulnar deviation is affected by gender, manual labor, playing a musical instrument, playing sport, handedness, previous fr...

A family with proximal radioulnar synostosis segregating in three generations is described. Familial radioulnar synostosis is a rare anomaly; however, the sporadic form is a frequent feature in cases of sex chromosome abnormalities and other syndromes. This disorder has been reported in several ethnic groups, but this is apparently the first example from the black population.

Synovial osteochondromatosis of the distal radioulnar joint is a rare entity with only 14 cases reported in the literature. Malignant transformation of synovial osteochondromatosis is the most worrisome complication of the disease. It has been described in joints such as the hip and knee but never for the distal radioulnar joint. We report a case of synovial osteochondromatosis of the distal ra...

during the last 10 years, we have had 11 cases of radioulnar (ru) synostosis, a very rare congenital amomaly of the upper extremity. only 3 of them required surgical intervention. so we evaluated these three cases of proximal radioulnar synostosis corrected by proximal derotational osteotomy. the indication for surgery was severe pronation deformity that caused functional problem. mean age at t...

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...
