Hallux valgus surgery aiming for three-dimensional correction using a plantar locking plate

Abstract

Hallux valgus is a common disease of the foot in females that is treated with various surgical procedures. To prevent the recurrence, I think the ideal correction is three-dimensional correction considering the postoperative weight-bearing position. I have performed proximal oblique metatarsal osteotomy combined with distal soft tissue treatment using a plantar locking plate for moderate to severe hallux valgus since November 2013. I introduce the concept of the three-dimensional correction and this operative technique.The results of the clinical evaluation are satisfactory (JSSF scale, intermetatarsal angle, hallux valgus angle, the sesamoid position, Inclination angle, SAFE-Q). Recurrence of hallux valgus deformity was found in about 5%. Use of a plantar locking plate provides sufficient maintenance of the correction and complications associated with hardware are rare. We need to study the biomechanical effectiveness of the locked fixation from the tension side of the construct.
