Traumatic medial luxation of the triceps brachii tendon with medial subluxation of the elbow joint in a dog.

OBJECTIVE

To describe the surgical reduction of luxation of the triceps brachii tendon in a dog.

ANIMAL: One 2.5-year-old 2.58 kg castrated male toy poodle.

STUDY

DESIGN

Clinical case report.

METHODS

The dog displayed intermittent, non-weight bearing lameness of the right forelimb for approximately 18 months before presenting at the veterinary medical center. Medial subluxation of the right elbow joint was detected by palpation. The Campbell test was consistent with an increased range of motion during supination. At ultrasonographic examination, medial luxation of the triceps brachii tendon was noted, whereas collateral ligaments appeared normal. No skeletal deformities were found on radiographs of the right forelimb. The luxation of the triceps brachii tendon was surgically corrected with antirotational suture, a stopper pin, medial retinaculum release, and imbrication of the lateral retinaculum.

RESULTS

The right triceps brachii tendon and elbow joint were successfully reduced. Gait returned to normal by 55 days postoperatively. No implant failure or recurrence were observed 3.5 years after surgery.

CONCLUSION

Surgical reduction of a luxation of the triceps brachii tendon in a dog resolved lameness and restored the range of motion of the affected elbow, leading to good long-term outcome.
