Akin Osteotomy, Hallux Valgus
Conditions
Brief summary
We hypothesize that the Akin screw fixation osteotomy technique provides better postoperative mobility of the metatarsophalangeal hallux joint compared to the non-fixation technique.
Detailed description
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).
Interventions
PROCEDUREAKIN osteotomy with screw fixation
A simple skin speck is made on the medial aspect of the hallux, in the metaphyseal area, using a 3 mm beaver blade. The tissue is lifted from the bone using an elevator medially and dorsally on the phalanx. A Shannon 2x12 mm burr is then positioned transversely by making the osteotomy which must preserve a lateral hinge, a guarantee of stability in the event of non-fixation. Fixation with a screw will be effected by another skin speckle allowing access to the infero-medial area of the phalangeal base. A pre-hole can be made with the same bur to facilitate the introduction of the guide wire for osteosynthesis, which is not specific.
PROCEDUREAKIN osteotomy without screw fixation
This is the same procedure as the procedure under study, without the fixation by a target: a simple skin speck is performed on the medial face of the hallux, in the metaphyseal area using a beaver blade. of 3 mm. The tissue is lifted from the bone using an elevator medially and dorsally on the phalanx. A Shannon 2x12 mm burr is then positioned transversely by making the osteotomy which must preserve a lateral hinge, a guarantee of stability in the event of non-fixation.
