A. For buck traction which one is incorrect?
B. A pillow placed under knee
The foot is 2 inch away from the foot plate
The Correct Answer and Explanation is:
For the question regarding Buck traction, the incorrect statement is:
B. A pillow placed under the knee.
Explanation:
Buck traction is a type of skin traction typically used to immobilize and align a fractured lower extremity, usually for fractures of the femur or hip. The goal is to reduce pain and muscle spasms by applying a pulling force to the affected limb, often in combination with other methods such as counter-traction (opposing force), to keep the limb in the desired position.
The key aspects of Buck traction are:
- Correct Application of Traction:
- Buck traction works by applying a steady pulling force via a rope or pulley system to the limb. This pulling force is directed along the long axis of the bone, which helps to align the fracture and reduce muscle spasms.
- The traction setup includes a foot plate or boot, which the patient’s foot rests on. The pulling force is exerted through a weight system, and the counter-traction is often applied by the patient’s body weight or the bed.
- Positioning of the Limb:
- The foot should be approximately 2 inches away from the foot plate. This is correct as it ensures that the traction is applied evenly without direct contact with the foot plate, avoiding pressure sores or discomfort.
- A pillow placed under the knee is incorrect because it can interfere with the alignment of the limb and reduce the effectiveness of the traction. The leg must remain fully extended to maintain correct alignment of the bone. The pillow could elevate the knee, changing the angle of the limb and compromising the proper alignment needed for optimal healing. Instead of placing a pillow under the knee, proper limb positioning is critical. Typically, the limb should be kept in neutral alignment without any support that may create additional pressure points or alter the alignment of the fracture.
Correct Traction Setup:
- The limb should remain fully extended with no support that alters its position.
- The traction system should maintain consistent tension, and the foot should be slightly off the foot plate to avoid direct pressure.
- Care should be taken to check for adequate circulation, skin integrity, and alignment.
Thus, the incorrect statement is about the pillow under the knee, which should be avoided in order to ensure that the Buck traction system works effectively to promote healing of the fractured limb.
