Congenital vertical talus (CVT), or "rocker-bottom" foot, describes the most severe form of congenital flatfoot. It is characterized by a rigid dislocation of the talonavicular joint, in which the navicular articulates with the dorsal aspect of the talus...
We describe vertical transmission of isolated CVT in four separate families and confirm that autosomal dominant inheritance should be considered in the differential diagnosis of isolated CVT.

Congenital Vertical Talus. Account of the condition, its investigation and management.

Core Curriculum
Objectives
1. Describe the pathology of congenital vertical talus
2. Describe a rational approach to treatment based on the pathology
3. List conditions described as being associated with congenital vertical talus
4. Describe the assessment of the newborn with congenital vertical talus
Discussion points
1. At what age should surgery be performed, and why?
2. After the diagnosis has been made in the newborn, what type of workup is indicated?
3. How should the newborn be treated?
4. Is there a genetic component to the etiology of congenital vertical talus?

irreducible dorsal dislocation of the navicular on the talus w/ fixed talo-navicular complex;
- CVT is a common cause of rigid flat foot, which can be isolated, or can occur with chromosomal abnormalities, myeloarthropathies (myelomeningocele), & neurologic disorders;

This lecture covers:
* Talipes deformities (clubfoot)
* Pes planus (flat feet)
* Congenital vertical talus
* Pes cavus
* Tarsal coalitions
