Description
Summary:A recently described metaphyseal irregularity of the radius and ulna was diagnosed radiographically in a significant proportion of Newfoundland dogs during the course of a large study. This case report describes the pathological picture of a Newfoundland dog with these radiographic changes. The lesions in the distal radius and ulna were characterized by focal, longitudinal striations of sclerosis of the bone marrow cavity, surrounding thin trabeculae of primary spongiosa of the distal metaphysis. It is suggested that these lesions represent a sclerosing dysplasia not previously described in dogs, but with some similarities to the human disorder, osteopathia striata.
