Surgical Treatment of Moderate Hallux Valgus: A Comparison of Distal Chevron Metatarsal Osteotomy With and Without Lateral Soft-Tissue Release

Abstract

Purpose: The purpose of the study was to determine whether lateral soft-tissue release (LSTR) has a beneficial or detrimental effect on the outcome of distal Chevron first metatarsal osteotomy (DCMO) in the treatment of moderate hallux valgus (HV). Methods: We compared the effect of different surgical treatments in 2 groups of patients: group I (23 patients, 25 feet, average age of 55 [from 43 to 77] years) was subjected to DCMO only, whereas group II (18 patients, 23 feet, average age of 59 [from 52 to 70] years]) was subjected to DCMO with LSTR. The American Orthopaedic Foot and Ankle Society’s Hallux Metatarsophalangeal-Interphalangeal scale survey was conducted postoperatively, followed by the brief survey on postoperative patient satisfaction. The patient follow-up period was from 18 to 24 months after surgical treatment, on average. Results: After surgical intervention, both groups of patients presented with an improved HV angle, but there was no significant difference between the groups. However, group II showed significant improvements in medial sesamoid bone position and patient satisfaction scores as compared with group I. Conclusion: Our midterm follow-up of surgical treatments for moderate HV deformity suggests that both procedures provide good postoperative results. However, according to our results, DCMO with LSTR provides better results than procedures without LSTR. Levels of Evidence: Therapeutic, Level III: Retrospective comparative study
