In treatment for a femur fracture, which method was employed in Johnny's case?

1. Skin traction

2. Plaster cast immobilization

3. Surgical insertion of pins

4. Open reduction

The correct answer is: Skin traction

In the context of treating a femur fracture, skin traction is a method that involves the application of a pulling force to the extremity through the skin. This technique is typically used to reduce the fracture and align the bones in a stable position, allowing for the healing process to begin. Skin traction is particularly useful for managing certain types of fractures without the immediate need for surgical intervention. This approach can help control pain and muscle spasms while keeping the limb stable. It's often a preliminary step before more definitive treatments, such as surgical intervention or casting, are instituted, especially if there is significant swelling or if surgery needs to be postponed. While other methods like plaster cast immobilization, surgical insertion of pins, and open reduction are common for addressing femur fractures, each has specific indications and is usually considered in different contexts. Plaster casts are more suitable for stable fractures post-reduction, surgical pinning is generally reserved for more complex cases or when internal fixation is required for proper alignment, and open reduction involves surgical exposure of the fracture to ensure proper alignment and stabilization, typically used for cases with significant displacement. Hence, choosing skin traction can indicate the situation where less invasive measures are desired and can be effective in the management of this type of injury.
