Thirty-one patients (forty-five feet) who had metatarsus adductus were
evaluated at our institution and were followed for an average of thirty-two
years and six months. Of these thirty-one patients, twenty-one (thirty-one
feet) were examined clinically and radiographically. Information on the
remaining ten patients (fourteen feet) was obtained by letter or telephone,
or both. Twelve patients (sixteen feet) who had a passively correctable
deformity (mild or moderate) at the time of the initial presentation had no
treatment. Twenty patients (twenty-nine feet) who had a partly flexible or
rigid deformity (moderate or severe) at the time of the initial
presentation were managed with serial manipulation and application of
plaster holding casts. (One patient who had a bilateral deformity had no
treatment on one side and conservative management on the other). The
results were good in all sixteen of the untreated feet and in twenty-six
(90 per cent) of the twenty-nine feet that had been conservatively treated.
There were no poor results. The passively correctable deformities resolved
spontaneously. Radiographs showed an obliquity of the medial
cuneiform-metatarsal joint in twenty-one (68 per cent) of the thirty-one
feet that were examined clinically and radiographically. Similar findings
were observed in four of eleven contralateral, normal feet. Hallux valgus
was not a common outcome. No patient had operative correction.
