Presentation
Presented with 3-month history of a right front lameness with pain on elbow manipulation.
Patient Data
Right elbow: The anconeal process is un-united. There is osteophyte formation on the anconeal process. There is remodeling and osteophyte production involving both epicondyles. There are focal area of sclerosis of the proximal ulna.
Left elbow: There is a small osteophyte of the medial ulna with periosteal reaction along the medial aspect of the proximal ulna. There is a small osteophyte on the anconeal process and sclerosis in the proximal ulna.
Impression:
Bilateral elbow dysplasia with suspected medial coronoid disease and right ununited anconeal process. Bilateral osteoarthrosis. Panosteitis on the right.
Case Discussion
Although there is only lameness in the more affected right limb, elbow dysplasia often affects both limbs. The medial coronoid process is not well visualized on the radiographs, however the secondary signs of osteoarthrosis on the medial ulna is indicative of disease. The flexed lateral view gives the best projection of the anconeal process and any osteophytes forming on it. The sclerosis near the trochlear notch of the ulna is likely secondary to the elbow dysplasia. However the more distal focus of sclerosis in the right ulna is likely panosteitis, common in this age and breed.
