Study on Akin Osteotomy: Fixation Versus Non-fixation (Fixakin)

Randomized Study on Akin Osteotomy: Fixation Versus Non-fixation

We hypothesize that the Akin screw fixation osteotomy technique provides better postoperative mobility of the metatarsophalangeal hallux joint compared to the non-fixation technique.

Compare the screw fixation technique of Akin's osteotomy, compared to the technique without fixation, on the postoperative mobility of the metatarsophalangeal joint of the hallux at one year postoperatively in patients ( patients operated on for an isolated hallux valgus, that is to say without any associated lateral movement, by percutaneous technique (MICA or PERC).

Inclusion Criteria:

• Patient over 18 years-old
• Patient undergoing percutaneous surgery for Hallux valgus with first hybrid and / or percutaneous ray procedure without rotation disorder,
• First line surgery,
• Absence of metatarsophalangeal osteoarthritis,
• Persistence of mobility of the hallux metatarsophalangeal gland,
• Subject benefiting from a social protection insurance
• Patient having signed the free and informed consent / Patient having given his express consent / Patient having been informed and not opposing this research.

Exclusion Criteria:

• Rotation disorder,
• Rheumatoid foot,
• Hallux rigidus.
• Patient participating in another clinical study
• Minors:
• Adults under guardianship, curatorship or other legal protection, deprived of their liberty by judicial or administrative decision;
• Pregnant, breastfeeding or parturient woman;
• Hospitalized without consent.
