Purpose: We assessed the treatment result of the distal chevron osteotomy in the patients with moderate to severe hallux valgus.
Material 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°, 15.8° in moderate cases and 44.1°, 17.3° 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: Radiologic evaluation revealed hallux valgus angle and 1st-2nd intermetatarsal angle in moderate cases to be 13.0°, 11.3°(postoperatively and in severe cases 15.6°, 10.9°, postoperatively. On final follow up, the results were 14.5°, 11.6° in moderate cases and 18.3°, 11.9° in severe cases, respectively.
Conclusions:Distal chevron osteotomy can be usefully applied to the treatment of moderate to severe hallux valgus.
