Purpose: We assessed the treatment result of the distal chevron osteotomy in the patients with moderate to severe hallux valgus. Materials and Methods: In a total of 28 cases of hallux valgus in 20 patients, underwent distal chevron osteotomy between July 1999 and February 2001, were enrolled in this study. 21 cases were moderate and 7 cases were severe. The preoperative average hallux valgus angle and 1st-2nd intermetatarsal angle of the two groups were $31.5^{circ}$, $15.8^{circ}$ in moderate cases and $44.1^{circ}$, $17.3^{circ}$ in severe cases, respectively. Radiologic evaluation was done preoperatively, postoperatively and on the final follow-up visit using weight-bearing radiographic imaging to determine the hallux valgus angle and 1st-2nd intermetatarsal angle. Results: Radiographic evaluation revealed hallux valgus angle and 1st-2nd intermetatarsal angle in moderate cases to be $13.0^{circ}$, $11.3^{circ}$ (postoperatively and in severe cases $15.6^{circ}$, $10.9^{circ}C$, postoperatively. On final follow up, the results were $14.5^{circ}$, $11.6^{circ}$ in moderate cases and $18.3^{circ}$, $11.9^{circ}$ in severe cases, respectively. Conclusion: Distal chevron osteotomy can be usefully applied to the treatment of moderate to severe hallux valgus.
