摘要

A 6-month-old female Rottweiler was evaluated because of a non-weight-bearing lameness of the left forelimb. The owners reported that the lameness developed acutely after the dog jumped from the bed of a pickup truck. Physical examination localized the lameness to the left elbow. Orthopedic examination with the dog anesthetized revealed mild to moderate swelling around the left elbow and crepitus on flexion and extension of the affected joint. Lateral instability of the elbow was also apparent. Survey radiographs of the left elbow were obtained (Fig 1).
