Idiopathic Congenital Vertical Talus (CVT)

CVT is a rare, severe, important deformity. This case report is to highlight the importance of deformity and early notification. Surgical correction as one stage procedure is probably the best procedure. CVT has no sex prevalence, bilateral in 50% of cases and more than 50% of cases a secondary cause implicated. Pathological anatomy involves dislocation of the talonavicular articulation with the oscalcis. Navicular bone is displaced onto the dorsolateral aspect of the talar head. Diagnostic criteria for CVT were persistent talonavicular dislocation on forced plantar flexion of foot. Talus axis and metatarsal base axis angles (TAMBA) and Calcaneal Axis and metatarsal axis (CAMBA) are introduced. TAMBA and CAMBA enable us to describe the obliquity of the talus and calcaneus, also the severity of the dislocation of the talonavicular joint and the contracture of the tendo Achilli. The current treatment is a one-stage open reduction of the talonavicular dislocation, combined with a posterior release. A subtalar bone block is often imperative to maintain correction. The surgery for (CVT) can lead complications.
