Case Study

RAD – Bilateral elbow dysplasia with medial coronoid pathology in a 3 year old MN Labrador Retriever

This 3 year old MN Labrador Retriever mix has a history of chronic right fron lameness that is worse after exercise.

Image Interpretation

right and left elbows: The cranial contour of the medial coronoid process (PCM) is blurred and reduced inopacity. Asymmetry of the humeroradial and humeroulnar joint space is noted withmild narrowing of the humeroulnar joint space and a mild radioulnar step formation. A mild amount of osteophytes are noted at the proximocranial aspect of the radius andmproximal surface of the anconeal process as well as sclerosis of the trochlear notch of the ulna.

right and left carpi: A minimal osteophyte formation is noted at the dorsal aspect of the carpometacarpal joint.

DX

Bilateral elbow dysplasia in terms of medial coronoid pathology and mild elbow joint incongruity with mild secondary osteoarthritis

Outcome

CT of both elbows and arthroscopy (arthrotomy) of the right elbow is recommended.
Consider surgical revision of the left elbow joint as well depending on the results of
the CT or in case of clinical lameness of the left front limb.
