What is the positioning of the talus in congenital vertical talus?

• A. Inclined anteriorly
• B. Vertical, parallel to tibia
• C. Laterally deviated
• D. Internally rotated

Answer: (B)

In congenital vertical talus, the positioning of the talus is characterized by its vertical alignment, which is parallel to the tibia. This condition is a form of rigid flatfoot, where the talus does not maintain its normal anatomical position during development. The vertical orientation of the talus, in relation to the tibia, contributes to the flatfoot deformity associated with this condition.

The vertical positioning results in an abnormal relationship between the talus and the surrounding structures, including the hindfoot and midfoot. This misalignment can lead to functional issues, such as difficulty with walking and stability, as the normal biomechanics of the foot are disrupted. Understanding this positioning is crucial for clinicians when diagnosing and formulating treatment plans for patients with congenital vertical talus.

In summary, recognizing that the talus is positioned vertically and parallel to the tibia is a key component in understanding the structural abnormalities that characterize congenital vertical talus.
