Introduction:

Congenital vertical talus, also known as congenital convex pes valgus or "rocker-bottom foot," is a rare foot deformity that is present at birth. It is characterized by a rigid or fixed dorsal dislocation of the talonavicular joint, leading to a prominent convexity of the foot's plantar surface. This comprehensive article aims to provide a thorough understanding of congenital vertical talus, including its causes, clinical features, diagnostic methods, potential complications, and treatment options.

Causes and Development:

The exact cause of congenital vertical talus is often unknown. It is believed to result from a combination of genetic and environmental factors. It may occur sporadically or be associated with underlying genetic syndromes, such as arthrogryposis or spina bifida. In some cases, the condition may be present in multiple family members, suggesting a familial component.

Clinical Features:

Congenital vertical talus can present with the following clinical features:

• Convex plantar surface: The affected foot exhibits a convex or "rocker-bottom" appearance due to the prominence of the talus bone on the plantar surface.
• Rigidity: The foot is rigid and cannot be brought into a normal anatomical position manually.
• Dorsiflexion limitation: The dorsiflexion (upward bending) of the foot is severely restricted.
• Hindfoot valgus: The hindfoot is displaced in a valgus (outward) direction, away from the midline of the body.
• Midfoot dorsiflexion crease: A prominent crease is seen across the midfoot when the foot is manipulated.

Diagnostic Methods:

The diagnosis of congenital vertical talus involves a combination of clinical evaluation, physical examination, and imaging studies. Diagnostic methods may include:

• Clinical evaluation: A healthcare professional will assess the appearance and range of motion of the foot, as well as evaluate for any associated abnormalities or syndromes.
• X-rays: X-ray imaging can help confirm the diagnosis, evaluate the alignment of the bones, and assess any associated skeletal abnormalities.
• Other imaging studies: Additional imaging techniques, such as ultrasound or MRI, may be used to further evaluate the foot's soft tissues and associated structures.

Potential Complications:

Congenital vertical talus can lead to potential complications, including:

• Foot deformity: If left untreated, the foot deformity can cause significant functional limitations and difficulties with walking and standing.
• Associated conditions: Congenital vertical talus may occur in association with other genetic syndromes, which can present additional challenges and complications.

Treatment Options:

The management of congenital vertical talus aims to correct the deformity and improve foot function. Treatment options may include:

• Serial casting: Non-surgical treatment often begins with serial casting, where the foot is gradually manipulated into a corrected position and held in place with a series of casts.
• Stretching and splinting: Stretching exercises and the use of splints or orthotic devices may be recommended to maintain the correction achieved with casting.
• Surgical intervention: In cases where non-surgical methods are unsuccessful or the deformity is severe, surgical procedures may be performed to realign the foot's structures and stabilize the joint.

Long-Term Outlook and Support:

The long-term outlook for individuals with congenital vertical talus depends on the severity of the condition, response to treatment, and individual factors. Regular follow-up, monitoring, and ongoing support from healthcare professionals can contribute to optimal outcomes and functional abilities.

Conclusion:

Congenital vertical talus is a rare foot deformity characterized by a rigid or fixed dorsal dislocation of the talonavicular joint. By understanding its causes, clinical features, diagnostic methods, potential complications, and treatment options, healthcare professionals can work together to provide appropriate management and support for infants with congenital vertical talus, promoting their mobility and overall well-being.
