We evaluated 20 cases (12patients)of hallux valgus that performed modified Lapidus procedure. We asked to patient about postoperative satisfaction in terms of overall, pain, and appearance. preoperative and postoperative AOFAS score for the forefoot was calculated, also preoperative and postoperative radiologic evaluation was done. Results: In terms of satifaction, overall rate was 70%, pain relief and appearance were 70% and 70%. preoperative mean Hallux valgus angle and mean intermetatarsal angle were 42.6degree and 19.4degree. after procedure, at last follow up, mean hallux valgus angle and mean intermetatarsal angle were 16degree and 8.7degree. In terms of complication, nonunion was seen in 3 cases and recurrence of hallux valgus deformity was 2 cases.
