Purpose:
This study aimed to detect the effect of a modified chevron osteotomy on hallux valgus (HV) deformity at five-year follow up.
Methods:
Twenty patients with symptomatic HV who underwent modified chevron osteotomy between June 2014 and January 2016 were included in the present study. The minimum follow-up duration was five years. Each patient was evaluated preoperatively, six weeks postoperatively and five years postoperatively using the visual analog scale (VAS) pain score, the American Orthopedic Foot & Ankle Society (AOFAS) score and cosmetic and radiological outcomes.
Results:
The AOFAS score improved from 54.40 ( ± 4.58) preoperatively to 94.30 ( ± 2.15) six weeks postoperatively (p < 0.001) and 96.95 ( ± 1.54) five years postoperatively (p < 0.001). The VAS scores decreased from 6.30 ( ± 1.17) preoperatively to 0.15 ( ± 0.37) five years postoperatively (p < 0.001). The mean intermetatarsal angle improved from 16.00° ( ± 2.20°) preoperatively to 4.15° ( ± 1.22°) six weeks postoperatively (p < 0.001) and 4.40° ( ± 1.39°) five years postoperatively (p < 0.001). The mean HV angle also improved, from 32.70° ( ± 5.34°) preoperatively to 4.80° ( ± 1.40°) six weeks postoperatively (p < 0.001) and 5.20° ( ± 1.32°) five years postoperatively (p < 0.001). The cosmetic results were either excellent or good in 19 patients (95%). There was no recurrence in this study during the five postoperative years.
Conclusion:
A modified chevron osteotomy can achieve successful correction of moderate-to-severe HV, with excellent outcomes at five-year follow up.
