CUE – Canine Unicompartmental Elbow

surgical option for end-stage elbow dysplasia involving the medial compartment


Symptoms of Elbow Dysplasia:

Abnormalities begin to show during rapid growth phases in puppies, usually between 4 and 10 months of age (however sometimes the symptoms are not apparent until the dog is older).

– changes in activity level

– limping

– swollen elbows

– pain in the elbows

– decreased performance

– behavioral changes


Your regular veterinarian may notice joint thickening and swelling and, through palpation and manipulation of the joint, should be able to diagnose the problem as elbow dysplasia. X-Rays and/or a CT Scan may also be used to determine the extent of the problem.

A board certified surgeon will discuss treatment options with you. If your dog suffers from FCP (Fragmented Coronoid Process), an arthoscopy may be performed to remove the bone fragments and slow the progression of osteoarthritis. However, it does not affect a cure and the osteoarthritis will need to be monitored for the remainder of your dog’s life.

The result of the progression of osteoarthritis eventually will lead to bone-on-bone grinding on the medial, or inside, portion of the elbow joint.


The CUE, or Canine Unicompartmental Elbow, was developed to address this bone-on-bone grinding by focusing on the specific portion of the joint that is affected, namely the Medial Compartment. A CUE implant is placed in the medial compartment to preserve the good cartilage and lessen the pain that is associated with the bone-on-bone grinding.


There will need to be strict exercise restriction for 8-10 weeks post CUE surgery. Full return to athletic function can be expected six months post surgery.
