title: The oldest case yet reported of osteoarthritis in a dog: an archaeological and radiological evaluation.
abstract: A century ago the remains of a dog skeleton were found in an archaeological double human burial, near Bonn-Oberkassel (Germany). Recent re-examination of the dog remains revealed that they were about 14,500 years old. Based on the growth plates, the animal was considered to be approximately 7·5 months old at the time of death. Based on the minimal humeral diameter, it was calculated that it was approximately 0·47 m tall at the shoulder and weighed approximately 15·7 kg. The right proximal ulna of this skeleton showed osteoarthritis, manifested by an osteophyte of 5×3×1·5 mm3at its cranial edge, with no identified primary developmental causes for osteoarthritis. Osteochondritis dissecans, joint incongruity and trauma are possible aetiologies. The left ulna did not reveal any abnormalities.
