Comparison of Three-Dimensional Displacement Among Different Metatarsal Osteotomies

Hallux valgus is a slowly progressing complex 3-dimensional biomechanical process. Therefore, precise understanding of 3-dimensional deformity is essential for satisfactory clinical result. Uniplanar correction on anteroposterior view of foot would be insufficient, and rotation on frontal plane as well as sagittal alignment should also be well corrected. This article will review the 3-dimensional components of bony displacement in different surgical methods for hallux valgus correction.
