Ligament supporting the head of talus is
**Core Concept**
The talus bone in the foot is supported by several ligaments, which provide stability and facilitate movement. The ligament supporting the head of the talus is crucial for maintaining the integrity of the ankle joint.
**Why the Correct Answer is Right**
The correct ligament supporting the head of the talus is the **Deltoid Ligament**. This ligament is a strong, fibrous band that connects the medial malleolus of the tibia to the medial surface of the talus. The deltoid ligament plays a vital role in stabilizing the medial aspect of the ankle joint and preventing excessive movement. The deltoid ligament consists of two layers: superficial and deep. The superficial layer consists of four bands, while the deep layer is a strong, fibrous band that provides additional support to the talus.
**Why Each Wrong Option is Incorrect**
**Option A:** The **Anterior Talofibular Ligament (ATFL)** is the most commonly injured ligament in the ankle joint, but it does not support the head of the talus. The ATFL connects the anterior aspect of the fibula to the talus and is prone to injury during inversion movements.
**Option B:** The **Posterior Talofibular Ligament (PTFL)** is another ligament that connects the posterior aspect of the fibula to the talus, but it does not support the head of the talus. The PTFL is less commonly injured compared to the ATFL.
**Option D:** The **Calcaneofibular Ligament (CFL)** is a ligament that connects the fibula to the calcaneus, but it does not support the head of the talus. The CFL is also prone to injury during inversion movements.
**Clinical Pearl / High-Yield Fact**
When evaluating ankle injuries, it's essential to consider the mechanism of injury and the specific ligaments involved. The ATFL is commonly injured during inversion movements, while the deltoid ligament is more commonly injured during eversion movements.
**Correct Answer: C. Deltoid Ligament**
