Modified minimally invasive chevron osteotomy versus traditional incision chevron osteotomy

Area of Science:

• Orthopedic surgery
• Foot and ankle procedures
• Minimally invasive surgery

Background:

• Hallux valgus is a common foot deformity requiring surgical correction.
• Chevron osteotomy is a standard surgical technique for hallux valgus.
• Minimally invasive approaches aim to reduce surgical trauma and improve recovery.

Purpose of the Study:

• To compare the efficacy and outcomes of modified minimally invasive chevron osteotomy (MIC) versus traditional incision chevron osteotomy (TIC).
• To evaluate clinical and radiographic results for mild to moderate hallux valgus correction.

Main Methods:

• Retrospective study of 42 patients (60 feet) with mild to moderate hallux valgus.
• Patients were divided into MIC (20 patients, 28 feet) and TIC (22 patients, 32 feet) groups.
• Clinical outcomes assessed using AOFAS hallux, lesser toe score, and VAS pain; radiographic outcomes measured HVA, 1-2IMA, and DMAA.

Main Results:

• Both MIC and TIC groups showed significant improvements in AOFAS scores, VAS pain, HVA, 1-2IMA, and DMAA post-surgery.
• No significant differences were observed in clinical efficacy or radiographic outcomes between the MIC and TIC groups.
• The MIC group had a significantly smaller incision length (2.06 cm) compared to the TIC group (5.04 cm).

Conclusions:

• Both modified minimally invasive and traditional chevron osteotomy effectively treat mild to moderate hallux valgus.
• Modified minimally invasive chevron osteotomy results in a smaller incision and less trauma compared to the traditional approach.
• Clinical efficacy and radiographic outcomes are comparable between the two surgical techniques.
