Since 1990, we have treated hallux valgus by corrective osteotomy, according to the Hammond procedure (modified Mitchell procedure). The results of this surgery were recently analyzed. The subjects of this study were 9 patients (for a total of 12 feet receiving surgery), including 2 males (2 feet receiving surgery) and 7 females (10 feet). The ages at the time of surgery ranged from 16 to 66 years (mean: 36.5 years). The postoperative follow-up periods ranged from 2 months to 3 years and 6 months (mean: 1 year and 11 months). In these subjects, we examined postoperative changes in the hallux valgus angle and the intermetatarsal angle (M1-M2) in comparison to their preoperative values. Taking into account the presence/absence and severity of pain and complaints pertaining to the use of shoes, an overall assessment of surgical results was made, using the Glynn's criteria.
The mean hallux valgus angle was 35.4 degrees before surgery and 19.8 degrees after surgery. The intermetatarsal angle was 15.3 degrees before surgery and 10.1 degrees after surgery. No patient developed non-union. According to Glynn's criteria, 7 feet were rated as excellent, 5 feet as good and no feet were rated as unsatisfactory.
The modified Mitchell procedure is recommended for surgical treatment of hallux valgus on the grounds that its results are stable and satisfactory.
