Evaluation of radiographic and genetic aspects of hereditary subluxation of the radial head in Bouviers des Flandres

Abstract

Congenital radial head luxation and subluxation in the studied Bouviers des Flandres were characterized by angulation of the radial axis leading to caudolateral subluxation of the radial head and insufficient growth of the distal portion of the ulna together with cranial bowing of the olecranon.

Radiographic features of presumed congenital subluxation of the radial head in three Newfoundland littermates

“…The radiographic findings described in these three Newfoundlands are similar to the radial head subluxation described in multiple breeds (Bingel & Riser 1977; Milton and others 1979; Kene and others 1982; Temwichitr and others 2010) and can be classified as congenital elbow luxation type I (Kene and others 1982). As no affected puppies were radiographed or euthanased and examined via necropsy at birth, we cannot confirm that the cases described here were truly congenital in nature.…”

Correction of Biapical Radial Deformities by Use of Bi‐Level Hinged Circular External Fixation and Distraction Osteogenesis in 13 Dogs

“…Lateral radial head subluxation is not commonly described in dogs with antebrachial deformities. It has been reported in chondrodysplastic Bouvier des Flandres . These dogs seemingly had biapical radial deformities.…”

Ultrasonographic and Anatomic Study of the Canine Elbow Joint

“…Thoracic limb lameness in dogs is often localized to the elbow joint and it is important to correctly identify the cause of pain for accurate treatment . Differential diagnosis of elbow lameness of the dog includes flexor enthesopathy, non‐traumatic elbow joint luxation, traumatic disorders such as the jumping down syndrome, and congenital and developmental disorders like luxation, asynchronous growth, and elbow dysplasia . Elbow dysplasia includes 4 primary lesions: osteochondrosis of the medial humeral condyle, ununited anconeal process, incongruity of articular surfaces, and medial coronoid disease .…”
