Overview
Congenital vertical talus (CVT) is a rare congenital foot deformity characterized by a rocker-bottom appearance due to a complete dislocation of the talonavicular joint and supination of the foot. 1Diagnosis
Clinical examination revealing a rocker-bottom foot shape and limited dorsiflexion.
Radiographic confirmation showing characteristic joint dislocations and alignment issues.
Differentiation between idiopathic and syndromic cases may require additional clinical and genetic assessments. 1Management
First-line Treatment: Minimally invasive approach (Dobbs method/reverse Ponseti technique) involving soft tissue manipulation and serial casting.
Timing: Early intervention, typically commencing treatment around 6 months of age.
Follow-up: Long-term follow-up necessary to assess outcomes, with mean follow-up periods often exceeding 6 years. 1Special Populations
Pediatrics: Early intervention is crucial for optimal outcomes in pediatric patients with CVT. 1
Comorbid Syndromes: Treatment outcomes may vary between idiopathic and syndromic cases, requiring tailored approaches. 1Key Recommendations
Initiate minimally invasive treatment (Dobbs method/reverse Ponseti technique) for congenital vertical talus early, ideally around 6 months of age, to achieve better outcomes. (Evidence: Moderate) 1
Conduct long-term follow-up evaluations, typically over 6 years, to monitor the effectiveness and durability of the treatment. (Evidence: Moderate) 1
Consider individualized treatment strategies based on whether the CVT is idiopathic or associated with a syndromic condition, given potential differences in outcomes. (Evidence: Weak) 1References
