**Core Concept**
In orthopedics, the decision to perform an open reduction of a fracture depends on the fracture's location, stability, and displacement. Some fractures can be adequately managed with closed reduction and immobilization.

**Why the Correct Answer is Right**
Closed reduction and immobilization are sufficient for **intra-articular fractures of the calcaneus**. The calcaneus has a rich blood supply and a relatively low risk of avascular necrosis, making it amenable to closed reduction. Additionally, the calcaneus has a wide range of motion, allowing for some degree of compensation for minor articular incongruity. The main goal of treatment is to restore pain-free mobility and prevent further complications.

**Why Each Wrong Option is Incorrect**
* **Option A:** Fractures of the femoral neck often require open reduction to achieve stable fixation and prevent avascular necrosis.
* **Option B:** Displaced fractures of the scaphoid bone may require open reduction to restore carpal alignment and prevent complications like nonunion or avascular necrosis.
* **Option C:** Fractures of the talus often require open reduction to restore articular congruity and prevent avascular necrosis.

**Clinical Pearl / High-Yield Fact**
When considering closed reduction for a fracture, it's essential to evaluate the fracture's stability, the patient's overall health, and the potential risks and benefits of each treatment approach.

**Correct Answer: C. Fractures of the talus often require open reduction to restore articular congruity and prevent avascular necrosis.**
