Buck’s extension is an example of:
1.) skin traction
2.) skeletal traction
3.) balanced traction
4.) Bryant’s Traction
The Correct Answer and Explanation is :
The correct answer is:
1.) Skin traction
Explanation:
Buck’s extension is a type of skin traction commonly used in orthopedic treatment to alleviate discomfort from fractures, muscle spasms, or contractures. It is often applied to the lower limb to stabilize fractures, reduce pain, and prevent muscle spasms, particularly in cases of hip fractures or conditions like arthritis of the hip or femur.
Skin Traction:
Skin traction involves attaching traction devices (like adhesive strips or foam boots) directly to the skin. The force is applied externally by weights and pulleys, transmitting tension to the muscles and bones through the skin. Since skin traction does not involve inserting pins into the bones, it’s considered less invasive than skeletal traction.
How Buck’s Extension Works:
- In Buck’s traction, adhesive strips or foam boots are applied to the skin of the leg below the injury.
- A weight, typically between 5 to 10 pounds, is attached at the end of the traction system, providing a steady, gentle pull on the affected limb.
- The weight helps align the bone fragments, reduce muscle spasms, and relieve pressure on the injury site.
Indications:
Buck’s extension is primarily used in:
- Fractures of the femur, hip, or pelvis.
- Pre-operative or temporary stabilization of fractures before surgery.
- Muscle spasms associated with hip fractures.
- Other conditions such as dislocations or knee immobilization.
Difference from Skeletal Traction:
Unlike skeletal traction, where pins or wires are surgically inserted into the bone to apply force directly, skin traction like Buck’s extension applies the pulling force through the skin. Skin traction is typically used for shorter periods and less complex injuries due to its non-invasive nature and lesser pulling force.
In summary, Buck’s extension is an example of skin traction, offering a non-invasive method for temporary pain relief and stabilization in orthopedic injuries.
