Hindfoot varus increases the risk of damage to which structures of the foot and ankle?

• A. Medial ligaments
• B. Plantar fascia
• C. Lateral structures
• D. All ligaments equally

Answer: (C)

Hindfoot varus refers to a positional deformity where the hindfoot, which includes the heel bone (calcaneus) and the talus, is turned inward. This alignment places increased stress on the lateral structures of the foot and ankle, which include the lateral ligaments, such as the anterior talofibular ligament, calcaneofibular ligament, and posterior talofibular ligament, as well as the peroneal tendons. In a hindfoot varus position, the foot rolls inward during activities like walking or running, which can lead to compensatory mechanisms that increase strain on the lateral aspect. This altered mechanics can lead to repetitive stress injuries, tendonitis, or sprains of the lateral ligaments. Over time, such stress can result in chronic instability or joint problems on that side of the ankle. The other structures, such as the medial ligaments and plantar fascia, may also experience some degree of strain, but the predominant risk of damage as a result of hindfoot varus is focused on the lateral structures due to their specific involvement in the mechanics of inversion and ankle stability during movement. Therefore, the choice reflects a clear understanding of the anatomical and biomechanical implications of hindfoot varus.
