側方アプローチによる楔状骨切り術なしのV字型遠位大腿骨骨切り術による外反変形の矯正

Coronal-plane deformities of the knee are prevalent skeletal abnormalities in the adolescent population. Although valgus alignment is observed less frequently than varus alignment, it predisposes patients to several pathologic sequelae, including cartilage lesions, as well as degenerative changes within the lateral compartment leading to osteoarthritis, lateral patellofemoral joint instability, and attenuation of the medial collateral ligament. The current literature describes multiple modalities for distal femoral osteotomy such as lateral opening-wedge, medial closing-wedge, dome, wedge-less spike, and wedge-less V osteotomy techniques.
