The case of a boy, fourteen years old, with coxa vara in early childhood and with disseminated metaphyseal changes, is described. The patient was followed for fourteen years. The clinical features of most interest were the improvement in the metaphyseal changes in the proximal end of the femur after osteotomy in early childhood and the slipped epiphyses that appeared in puberty.
The laboratory findings were normal, except for an elevated excretion of acid mucopolysaccharides. This case is thought to be a form of metaphyseal dysostosis, perhaps a transitional form between the Jansen and Schmid types. Unfortunately, histological study of the metaphyseal region of bone and of the kidneys was not possible.
