Two year outcomes of minimally invasive hallux valgus surgery

Background

We report our experience with the Minimally Invasive Chevron Akin (MICA) technique for correcting hallux valgus, and evaluate its effectiveness and associated complications.

Methods

Case series of 13 feet with mild to moderate symptomatic hallux valgus treated surgically from July 2013 to December 2014, with at least 48-months follow-up. Patients were assessed pre-operatively and post-operatively with radiographical measurements (Hallux Valgus Angle (HVA) and Intermetatarsal Angle (IMA)) and clinical scores (American Orthopaedic Foot and Ankle Society (AOFAS), 36-Item Short Form Health Survery (SF-36), Visual Analog Scale (VAS)).

Results

Mean HVA and IMA decreased from 30.4° and 13.9°–10.9° and 10.2° respectively (p < 0.05). The mean AOFAS score improved from an average of 59.0–93.7 (p < 0.05). All patients reported a VAS score of 0 post-operatively, and the 4 SF-36 domains improved significantly (p < 0.05).

Conclusions

The MICA technique is a safe and effective method in the surgical correction of mild to moderate hallux valgus deformity, and continued use is justified.
