**Question:** Which of the following is the initial treatment of choice for Smith's fracture?

**Core Concept:** Smith's fracture is a type of fracture that occurs in the distal end of the radius, typically involving the articular surface. The goal of treatment is to maintain reduction and stabilize the fracture.

**Why the Correct Answer is Right:** The correct answer is A, "Plaster Cast." Applying a plaster cast is the initial treatment of choice for Smith's fracture because it helps maintain reduction, immobilizes the affected area, and provides support to the fracture site. A plaster cast also prevents further trauma and allows for proper healing.

**Why Each Wrong Option is Incorrect:**

B: Reduction and fixation with a splint is not as effective as a plaster cast. A splint does not provide the necessary stability and support required for fracture healing.

C: Surgery is usually reserved for complex fractures or those that cannot be reduced adequately with a plaster cast. In the case of Smith's fracture, a plaster cast is the primary treatment of choice.

D: Immobilization is essential in treating Smith's fracture, but option D, "Immobilization," is too broad and does not specify a suitable method like a plaster cast.

**Why Option A is Right and the Other Options are Wrong:**

Plaster cast is the correct answer because it provides the necessary stability and support required for fracture healing. Additionally, the other options are incorrect for the following reasons:

1. Reduction and fixation with a splint is not as effective as a plaster cast.
2. Surgery is typically reserved for complex fractures, and Smith's fracture can be managed with a plaster cast.
3. Immobilization is essential, but the answer should specify a suitable method, like a plaster cast, for optimal treatment.

**Clinical Pearl:**

In treating Smith's fracture, using a plaster cast is essential for maintaining reduction, stabilizing the fracture site, and promoting proper healing. This approach minimizes complications associated with surgery, such as infection, anesthesia risks, and potential implant failure.

**Correct Answer:** Plaster Cast (Option A)
