Abstract

PURPOSE
The purpose of this study is to evaluate the sequential changes of clinical and radiographic results after proximal chevron osteotomy in patients with moderate to severe hallux valgus.
MATERIALS AND METHODS
Between January 2008 and December 2009, 93 patients (117 feet) were treated with proximal chevron osteotomy and distal soft tissue procedure for symptomatic moderate to severe hallux valgus deformity. The mean age of patients was 51 years (range, 19 to 71) and the mean duration of follow-up was 27.5 months (range, 24 to 35). Clinical results were evaluated using visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) score preoperatively, at 3, 6, and 12 months after surgery, and at the last follow-up. Radiographic parameters including hallux valgus angle, intermetatarsal angle, and sesamoid position were evaluated preoperatively, immediately postoperatively, at 6 weeks, at 3, 6, and 12 months after surgery, and at the last follow-up.
RESULTS
VAS and AOFAS score showed significant improvement until 12 months after surgery. Hallux valgus angle and sesamoid position stabilized at 12 months after surgery and intermetatarsal angle stabilized at 6 months after surgery.
CONCLUSION
Clinical and radiographic results were stabilized beyond 12 months after proximal chevron osteotomy in patients with moderate to severe hallux valgus.
