Edited Ulna Ostectomy

Information about the procedure for referring vets.

Medial compartment disease is a progression of elbow dysplasia that results in loss of cartilage of the inner portion of the elbow joint. This results in bone rubbing on bone as the dog walks causing ongoing inflammation and pain in the joint.

When significant damage is seen, an ulna osteotomy is performed to allow the medial coronoid process to rotate away from the humerus by a small amount to reduce the conflict between the two surfaces and reduce pain.

The PAUL procedure is also designed to transfer weight from the inner half to the outer half of the joint to make use of the healthier cartilage in that region.

The choice between the two procedures is dependent on age and size.
