Retrospective study comparing Ludloff and minimally invasive Chevron Akin osteotomy for the correction of moderate to severe hallux valgus deformity

Background/purpose: To compare the radiographic and clinical outcomes of the Modified McBride's procedure with Ludloff osteotomy versus the minimally invasive Chevron Akin (MICA) osteotomy for the correction of moderate to severe hallux valgus deformity. Methods: A single-centre, retrospective study. The medical records of patients who underwent either procedure for the treatment of moderate to severe hallux valgus deformity: Hallux Valgus Angle (HVA) > 35˚, between September 2010 and April 2023 were reviewed and the demographic data was matched. Results: A total of 62 feet in 56 patients were included. The mean age was 62 years old and 79% were female. The mean preoperative HVA was 45.40 in the Ludloff group and 43.07 in the MICA group. Conclusions: Both demonstrated excellent radiographic and clinical outcomes. The choice may depend on surgeon preference and experience, as well as patient-specific factors such as activity level, and desire for a minimally invasive approach with smaller wound incision.
