this is a report of 2 very rare cases of Radio-ulnar dislocation-translocation in children from Kerman SHahid Bahonar haspital.this type of dislocation is very rare and only ten have been reported in the literature including  our report of two cases.in this type of dislocation the location of proximal ends of radius & ulna are altered,so that the capitellum articulates with the olecranon and...

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...

Synostosis or osseous union of any 2 adjacent bones can involve any part of the body. Synostosis between radius and ulna can take two forms, congenital and post Synostosis is a very rare congenital anomaly and most cases a post-traumatic, bilateral in 60% and more common in males. It is often part of syndromes such as Crouzon, Apert's and Poland's,4p Bixler syndrome, Genito multiple osteochondr...

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.

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...

The functional anatomy of the distal radioulnar joint was studied in relation to the whole forearm, using three fresh-frozen, above-elbow amputation specimens. The specimens demonstrate how the proximal and distal radioulnar joints together form a bicondylar joint of special character. The proximal "condyle," the radial head, rotates axially, whereas the distal "condyle," the ulnar head, is fix...

The purpose of this anatomic study was to evaluate potential causes of rupture of the distal biceps tendon, to assess the dynamic relationship of the proximal radioulnar joint during pronation and supination, and to identify potential sites of impingement of the distal biceps tendon. For the anatomic study specimens were evaluated by light microscopy, multiplanar gross dissections, and Spalteho...

Radioulnar synostosis is a rare pathological fusion of the tow forearm bones, when seen in pediatric must differentiate between congenital Synostosis versus post traumatic synostosis, radioulnar uncommon especially if it was closed fracture and treated conservatively. We describe 5 year old girl who presented with 1 following radial head subluxation, full pronation limitation supination compens...
