Anthropometric measurements of the scapula, humerus, radius and ulna in Labrador dogs with and without elbow dysplasia

Abstract

Labrador bitches diagnosed with ED have a shorter scapula, which is a new finding associated with this condition. The difference in presentation associated with gender is unexpected and further research is recommended.

Influence of chondrodystrophy and brachycephaly on geometry of the humerus in dogs

“…On the mediolateral radiographic view, humeral length was measured as the distance from the distal aspect of the humeral condyle to the cranioproximal aspect of the greater tubercle. Cortical and endosteal width were measured along lines placed perpendicularly at 30, 50, and 70% of humeral length (3,4,41,42). An ellipse was fitted to the humeral head to find its centre point.…”

“…It is thought that elbow dysplasia (ED) may be related to incongruity of radius and ulnar lengths, and articular formation in the elbow joint, but there is little information about bone lengths in Labrador dogs. Digital calliper anthropometric measurements of the Labrador scapula, humerus, ulna and radius, or their ratios, were used in this study to assess their relationship with ED 2 . The study included 103 Labrador dogs (41 dogs, 62 bitches) that had been previously classified by a specialist radiologist, using the ED radiological scores derived by the International Elbow Working Group, which includes fragmented coronoid process, osteochondritis dessicans, incongruity and ununited anconeal process.…”
