Subcapital talar osteotomy to correct transverse plane structural flatfoot deformities.

Subcapital talar neck adductory wedge osteotomies have significant benefits in the correction of angular deformities of the talar head in the pediatric flatfoot. Reconstruction of a severe flatfoot may include an Evans opening calcaneal osteotomy, a modified Young's tenosuspension with a posterior tibial and spring ligament advancement and a tendo Achillies lengthening. Talar neck osteotomies should also be considered in the presurgical evaluation of the pediatric and adolescent flatfoot with severe transverse plane deformity.
