Lateral: 8 month old Bassett hound

• Accurate patient positioning, though more difficult, remains important.
• The bone morphology is very different - for example the proximal ulnar is relatively large and unevenly shaped
• Fully flexed view reveals no sign of osteophytosis on the caudal anconeus.
• There is a marked "step" on the distal joint surface between the radius and the ulna. This is the consequence of the relative shortness of the ulna in chondrodystrophoid dogs. This step is usually (though not invariably) associated with elbow pain and OA.
