Abstract: Objective: To explore early effectiveness of modified minimally invasive Chevron-Akin (MICA) osteotomy in the treatment of moderate to severe hallux valgus. Methods: A clinical data of 49 patients (61 feet) with moderate to severe hallux valgus, who met the selection criteria between December 2019 and October 2022, was retrospectively analyzed. There were 7 males (8 feet) and 42 females (53 feet) with an average age of 38.0 years (range, 15-59 years), including 37 of unilateral foot and 12 of bilateral feet. There were 41 feet of moderate hallux valgus [hallux valgus angle (HVA) 20°-40°] and 10 feet of severe hallux valgus (HVA>40°). All patients underwent modified MICA osteotomy. A transverse osteotomy on the distal end of the first metatarsal bone was performed to replaced the traditional Chevron osteotomy, and three Kirschner wires were used to assist in three-dimensional correction. The other treatments were the same as traditional MICA osteotomy. The HVA, inter metatarsal angle (IMA), Hardy score of the sesamoid, and American Orthopaedic Foot and Ankle Society (AOFAS) score of 61 feet before operation and at last follow-up were recorded, and the results were compared between the various severity of hallux valgus. Results: >0.05). Conclusion: Modified MICA osteotomy can achieve good orthopedic effects and early functional improvement in the treatment of moderate to severe hallux valgus.
