A study has been made of the pathological character and, in most instances, of the response to treatment of fourteen cases of a congenital foot deformity, apparently to be recognized as a definite clinical entity, distinct from talipes equinovarus, yet one which is almost devoid of consideration in text and literature in the English language. The European Continental literature of the last twenty-five years was found to contain quite numerous references and case reports of this condition, including some of distinct value in the study and treatment thereof. Our analyses emphasize a dual nature of the skeletal deformity, and its marked resistance to complete correction. The general type of deformity may be properly subdivided into metatarsus adductus and metatarsus varus. In the former, satisfactory results can be expected from molding in plaster only. In the latter only milder grades are likely to respond to this technique, with the necessity of open intervention quite necessary for the more severe grades. In the latter, a muscle imbalance on a congenital basis may well be looked for, as illustrated by operative findings reported herein. The deformity is not well evaluated in most cases till after the first year and is more satisfactorily treated in ensuing years.
