Clinical and radiographic evaluation of Wilson osteotomy for hallux valgus.

Thirty-two Wilson osteotomies (26 patients) were evaluated after a mean follow-up time of 20 months. According to the classification of Bonney and MacNab, there were 90% good and excellent results. There was no correlation between the patient's appraisal of the result and the clinical result based on objective, functional, and radiographic data. The occurrence of metatarsalgia or callosities did not correlate with shortening or angulation. If there was a tendency to recurrence, there was a greater loss of correction with a longer duration of follow-up. In addition, patients over 50 seemed to have a greater tendency to recurrence than younger patients.
