Plain-English summary
A 13-month-old spayed female golden retriever and standard poodle mix was brought in for intermittent limping on her right front leg. The vet found swelling and limited movement in her right elbow, and imaging tests revealed a defect in the bone that looked like a cyst. During a procedure to look inside the joint, the vet discovered damage to the cartilage and inflammation around the area. This case is notable because it's the first time a subchondral bone cyst in a dog's ulna has been reported.

Abstract
A 13 mo old spayed female golden retriever/standard poodle mixed-breed dog was presented for intermittent right forelimb lameness. Physical examination revealed marked effusion and decreased flexion in the right elbow joint, radiography showed mild osteophytosis of the right elbow joint, and computed tomography showed a focal defect in the subchondral bone in the trochlear notch of the ulna resembling a subchondral bone cyst. Arthroscopy of the affected elbow revealed a focal defect in the articular cartilage on the trochlear notch with vascular ingrowth covering a defect in the subchondral bone plate. The synovium surrounding the defect was inflamed. To the authors' knowledge, this is the first published report of a subchondral bone cyst in the ulna of a dog.
