Abstract
A 12-year-old male poodle weighing 2.0 kg presented for evaluation of right thoracic limb lameness. The owner reported that the dog showed recurrent bilateral shoulder joint luxation after a car accident for a year. Recently, the left shoulder joint appeared well maintained, but right shoulder joint luxation was exacerbated. On physical examination, the dog showed non-weight bearing lameness on the right thoracic limb. Craniocaudal radiographic views revealed medial displacement of the right humerus. Mediolateral radiographic views revealed overlap of the glenoid cavity and humeral head. Muscle atrophy of the right thoracic limb, reduced biceps brachii muscle tendon tone, a tear of the medial glenohumeral ligament, and a rupture of the subscapularis tendon were identified intraoperatively. Transposition of the biceps muscle tendon was performed. However, at 7 days, there was evidence of right shoulder reluxation on radiographs. The second surgery was performed with two $2mm{\times}6mm$ cortical bone anchors and a $4mm{\times}6mm$ cancellous bone anchor placed in the cortical bone of the distal scapula and the cancellous bone of the proximal humerus respectively. Two scapular bone anchors were then connected with a humeral bone anchor using heavy nylon suture to minimize shoulder abduction range of motion. On radiographs right after surgery and 6 weeks after surgery, the affected limb revealed no evidence of medial shoulder luxation. At 6 months, no evidence of lameness was noted on the right thoracic limb.
