Summary

Deviation of the big toe in valgus at the level of the first metatarsophalangeal joint is called Hallux Valgus. In case of significant pain especially due to a conflict with the shoes, surgery could be indicated. Angle between the first metatarsal (M1) and the first phalangeal (P1) is named Hallux Valgus Angle (HVA). Angle between M1 and the second metatarsal (M2) is named InterMetatarsal Angle (IMA). Angle between M1 distal articular surface and M1 shaft axis in a frontal plane is named Distal Metatarsal Articular Angle (DMAA).

Insufficient surgical correction is a risk factor of recurrence (HVA\>20° after surgery). According to Okuda et al in a 67 patients group treated by proximal osteotomies correction, postoperative risk factors of recurrence at 33 month of follow-up are : HVA\>40° before the surgery and HVA\>15° with an IMA\>10° 10 weeks (3-24) after the surgery.

Currently, one of the most common used procedure is a translated (laterally) distal chevron associated with a release of the metatarso-sesamoid suspensory ligament and a Akin procedure on P1. Nevertheless this procedure does not correct deformation in all plans. HVA and IMA are corrected but DMAA and M1 pronation angle are not.

Surgeons can add three different osteotomies in this type of chevron. In the dorsal saw cut a varisation wedge osteotomy is possible , in the plantar saw cut a supination wedge osteotomy is possible, and both are possible. No studies have tried to assess these three possibilities.

The investigators hypothesize that the addition of a varisation and/or a supination wedge osteotomies in a distal chevron decrease risk factors of recurrence at six months of follow-up
