**Core Concept**
Fracture clavicle in infants is a common injury often resulting from birth trauma or minor accidents. The management of this condition requires consideration of the infant's age, the type of fracture, and the potential for complications. The goal of treatment is to minimize pain, prevent complications, and promote healing.

**Why the Correct Answer is Right**
The treatment of choice for fracture clavicle in infants is usually conservative management, which involves immobilization of the arm in a sling or a Pavlik harness. This approach allows for natural healing of the fracture while minimizing the risk of complications, such as brachial plexus injury or deformity. In some cases, the fracture may be managed with a figure-of-eight bandage or a clavicle splint to provide additional support and comfort. The key to successful treatment is to ensure that the infant's arm is properly positioned to prevent further injury and promote healing.

**Why Each Wrong Option is Incorrect**
* **Option A:** Surgical treatment is usually reserved for more complex fractures or cases where conservative management has failed. It is not the first-line treatment for fracture clavicle in infants.
* **Option B:** Reduction and casting may be used in some cases, but it is not the preferred treatment for fracture clavicle in infants due to the risk of complications and the need for close monitoring.
* **Option D:** Bracing or orthotics may be used in some cases, but it is not the primary treatment for fracture clavicle in infants.

**Clinical Pearl / High-Yield Fact**
Infants with fracture clavicle often present with a "dented" or "scooped" appearance of the clavicle on radiographs. This is due to the fact that the fracture may be difficult to visualize on plain X-rays, and the clavicle may appear deformed due to the displacement of the fracture fragments.

**Correct Answer: A.**
