The back is often forgotten as a cause or contributor to lameness, particularly in the bull. Close evaluation may lead to subtle findings such as a shuffling of the rear limbs or muscle atrophy of the lumbar muscles. Pelvic injuries can happen in both sexes of cattle, and sacroiliac injuries supporting ligamentous injuries and fractures to the ilium and ischium are possible [1]. Diagnostic anesthesia in the lower back is rarely effective due to the involvement of multiple structures in most back injuries. Acupuncture and chiropractic examinations may be of value in isolating the problem. Since most radiographic equipment available in practice cannot penetrate the body mass of most mature cattle, radiographs of the spine are of little value. Sometimes, all we can do is make an educated guess and come up with a conservative therapeutic plan.
