Congenital Talotarsal Joint Displacement and Pes Planovalgus Evaluation, Conservative Management, and Surgical Management

The diagnosis of and preferred treatment regimens for pediatric flatfoot, a complex and ambiguous deformity, continues to be debated. Incongruence of the talotarsal joint, whether flexible or rigid, is always present in pes planovalgus. However, it is important to note that talotarsal dislocation can occur without a flatfoot. The displacement of the talus on the hindfoot bones serves as the apex of the deformity. External measures, such as conservative care, are limited in providing correction to this internal deformity. Extraosseous talotarsal stabilization provides a minimally invasive internal option that should be considered before more radical surgical intervention is decided upon.
