Which form of skin traction is specifically known as Bucks extension?

1. Bucks extension

2. Russels traction

3. Skin traction

4. Pelvic traction

The correct answer is: Bucks extension

Bucks extension is a specific type of skin traction that is commonly used in orthopedic treatment, particularly for managing fractured femurs or hip injuries. This method involves the application of a pull on the affected limb to help maintain proper alignment and reduce pain. By anchoring the traction to the foot or distal limb and providing a counterbalance, Bucks extension effectively relieves muscle spasm and stabilizes the fracture site. The clarity of this method lies in its simplicity and effectiveness. It's often preferred for its ease of application and minimal invasiveness compared to more complex traction systems. The primary goal of Bucks extension is to provide alignment and stabilization through external means, using the skin as the interface to transmit the pulling force. Other forms of traction mentioned, while related in concept, serve different purposes or mechanisms. Russell's traction, for example, involves a more complex setup that includes both lower limb traction and countertraction, while pelvic traction typically targets the back and pelvis rather than the limbs. Therefore, identifying Bucks extension directly correlates with an established technique specifically recognized within the orthopedic field.
