Comparison of Operative Results of Distal Chevron Osteotomy with and without Akin Osteotomy for Moderate to Severe Hallux Valgus / 대한족부족관절학회지

ABSTRACT

PURPOSE: This study was conducted among patients with moderate to severe hallux valgus who underwent distal chevron osteotomy and groups of patients with or without Akin osteotomy were compared for evaluation of the relationship between their radiological and clinical outcomes. MATERIALS AND METHODS: From January 2009 to January 2012, among patients with moderate to severe hallux valgus who underwent distal chevron osteotomy at our institution, 28 cases with additional Akin osteotomy and 35 cases without Akin osteotomy available to follow up of more than one year were included in this study. For radiologic evaluation, hallux valgus angle, 1, 2 intermetatarsal angle, and hallux interphalangeal angle were measured before and after surgery. For clinical assessment, visual analogue scale score, American Orthopaedic Foot and Ankle Society score, subjective satisfaction of the patients, and passive range of motion of the first metatarsophalangeal joints were evaluated. RESULTS: At the final follow up, correction of valgus hallux angle and 1, 2 intermetatarsal angle was obtained from radiation results of both groups and it was found that patients who underwent Akin osteotomy showed radiographically larger angle correction but less subjective satisfaction. CONCLUSION: Patients with moderate to severe hallux valgus who underwent distal chevron osteotomy showed not only functional but also radiographically satisfactory results, and patients who underwent additional Akin osteotomy showed decreased subjective satisfaction. Therefore, if an incongruent first metatarsophalangeal joint is not observed, distal chevron osteotomy without Akin osteotomy seems preferable.
