Background: Cranial luxation of the scapulohumeral has been rarely reported in dogs and there is limited information available regarding surgical management of this condition, particularly with respect to long-term functional outcomes.
Case Description: This report describes the successful resolution of a chronic traumatic cranial scapulohumeral joint luxation in a dog which was stabilized by cranial transposition of the biceps brachii tendon of origin. At surgery, an osteotomy of the greater tubercle was performed and a trough was made in the exposed bed of the osteotomy. The transverse humeral ligament was incised, the bicipital tendon was levered into the trough and secured in that location by reattachment of the greater tubercle using multiple Kirschner wires and a figure-of-eight tension band wire. Post-operatively, the dog was maintained in a Spica splint for 2 weeks. Although surgical reduction was performed 4 months after the original injury, the luxation did not recur and the dog did not have appreciable lameness 14 months following surgery.
Conclusion: Although cranial transposition of the bicipital tendon is an invasive procedure, this dog’s scapulohumeral luxation did not recur and the procedure yielded an excellent long-term functional outcome.
