A 2-year-old castrated male Labrador Retriever was referred for evaluation of a left hind limb lameness of 3 weeks' duration. The dog had been struck by a car 3 weeks earlier, and craniodorsal luxation of its left hip joint was diagnosed on the basis of physical examination and radiographic findings (Figure 1). Luxation of the hip joint was treated by closed reduction and placement of an Ehmer sling for 10 days. After sling removal, the dog had a non—weight-bearing lameness in the left hind limb.
