Purpose: With differences between the sexes in foot bone anatomy and ligamentouslaxity, there is the possibility that the results of hallux valgus surgery may also differ between the sexes. We aimed to compare the results of hallux valgus surgery between the sexes. Materials and Methods: The authors retrospectively reviewed 60 males (66 feet) and 70 females (82 feet) who underwent distal or proximal chevron osteotomy for the treatment of hallux valgus deformity between June 2005 and December 2011. We compared the clinical and radiologic outcomes betweenthe sexes. Results: There were no statistically significant differences in demographicsbetween the sexes. The mean American Orthopedic Foot and Ankle Society score, visual analogue scale for pain, and patient satisfaction at the last follow-up did not differ significantly between the sexes. The mean preoperative halluxvalgus angle (HVA) and inter-metatarsal angle (IMA) were not significantly different between the sexes. At the last follow-up, the mean HVA was significantly greater in females (p=0.003) than in males; mean IMA was not significantly differentbetween the sexes. The mean correction of HVA in males was significantly greater than that in females (p=0.014). Conclusion: There were no significant differencesbetween the sexes regarding clinical outcomes after distal and proximal chevron osteotomy. However, male patients achieved greater correction of HVA than female patients. There is a possibility that sexual dimorphism of the foot may affect postoperative HVA.
