Minimally invasive surgery (MIS) is increasingly being used for bunion correction, but limited patient outcome data have been reported for third-generation minimally invasive chevron/Akin (MICA) techniques. The aim of this study was to report on radiographic outcomes, pain control, satisfaction, learning curve, and complication rates in a consecutive series of 94 patients undergoing MICA procedures for hallux valgus. It also describes strategies for avoiding perioperative complications that may arise with MIS bunionectomies.

In our experience, the MICA osteotomy was a safe and reproducible technique, associated with rapid improvement in pain scores, early weightbearing, significant deformity correction, high patient satisfaction, and low frequency of complications. In addition, the learning curve for the procedure was not as steep as previously reported.
