This dog is a 12 month old Labrador Retriever that was referred in for evaluation of a front leg lameness that had been present for the past 3-4 months. The dog was intermittent lame on the limb for the first 2 months, but the lameness had progressed to a moderate to severe lameness at the time of our exam. The owner reported that the animal became non-weight bearing on the limb with exercise. On exam, the animal exhibited severe pain on flexion and extension of the affected shoulder. After the initial exam, the owner opted for an MRI evaluation (See Images Below). A severe OCD lesion was noted on the MRI and also a joint mouse was diagnosed (free piece of cartilage in the joint). The recommendation was to take this animal to surgery and remove joint mouse and repair OCD lesion (See picture of cartilage piece that was floating free in the joint). The animal recovered normally from the surgery and the lameness had improved substantially in 10 days. The owner reported that the animal was doing great and had been put back to work 1 month after surgery.
