Primary flexor enthesopathy
Primary flexor enthesopathy (enthesitis) is a rare developmental disorder of tendon and ligament attachment within the canine elbow and is a contributory cause of elbow dysplasia.
This disease may present as a primary (less common, less severe) or secondary (concomitant) enthesopathy.
Affected dogs usually present with unilateral elbow pain, lameness and tenderness during elbow extension.
The disease involves the medial epicondyle, affecting the tendon attachments of the flexor muscles at the elbow.
Diagnosis is usually by ultrasonographic, arthroscopic, radiographic or CT examination, as well as exclusion of other elbow disorders such as fragmented coronoid process, osteochondritis dissecans, ununited anconeal process, incongruity, subtrochlear sclerosis, and osteoarthritis.
Secondary enthesopathy is usually associated with other degenerative joint changes such as fractured coronoid process or ununited anconeal process and require surgical intervention.
