Correction of moderate to severe hallux valgus with modified offset-V distal chevron and Akin osteotomy

Objective To evaluate the clinical efficacy and safety of modified offset-V distal Chevron and Akin Osteotomy in treating moderate to severe hallux valgus deformities. Methods From July, 2015 to October, 2016, 16 patients (2 men and 14 women, mean age of 38.5 years) 16 foot of moderate to severe hallux valgus deformities were treated with modified offset distal Chevron and Akin Osteotomy. The Hallux valgus angle(HVA), intermetatarsal angle (IMA), visual analogue scale(VAS) and American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal Interphalangeal Clinical Rating Score before operation were compared with that after the operation. Results All patients tolerated the procedure well. Complications such as avascular necrosis or bone nonunion were not demonstrated in the study. The HVA, IMA, VAS and AOFAS Hallux Metatarsophalangeal Interphalangeal Clinical Rating Score were improved obviously(P<0.01). Conclusion The modified Offset-V distal Chevron and Akin Osteotomy is a safe, conveniently and effective therapy for moderate to severe hallux valgus deformities.
