[Translated article] Short-term evaluation of minimally invasive Chevron-Akin osteotomy versus conventional Chevron:...

The choice of surgical technique for treating hallux valgus remains debated. Previous studies show favorable outcomes for both open and percutaneous techniques but do not conclude on their superiority. This study compares the functional outcomes of two groups of patients undergoing the minimally invasive Chevron-Akin (MICA) technique and the conventional technique, in short- and mid-term follow-up, using patient-reported outcome scores.

A prospective study was conducted on patients with moderate hallux valgus, divided into two groups: conventional Chevron-Akin osteotomy and MICA with fixation using three screws. Pre- and postoperative records were evaluated at 4 weeks, 6 months, and 12 months using the Manchester-Oxford Foot Questionnaire (MOxFQ), the AOFAS scale, and the visual analog scale (VAS). Complications were recorded. Subjective aspects such as surgical technique recommendation and time to return to normal footwear were also assessed.

Thirty patients were included in each group. Significant improvements were observed in functional scales post-surgery, but no differences were found between techniques. All patients recommended the surgery performed and returned to wearing normal footwear between the third and fourth postoperative weeks.

Both techniques show similar short- and mid-term outcomes and are effective in treating moderate hallux valgus. The choice of technique should depend on the surgeon's skills and experience.
