Which type of skin traction is applied to patients with fractures of the lower back and lower extremities?
A.
Buck’s traction
B.
Russell’s traction
C.
Bryant’s traction
D.
Dunlop’s traction
The Correct answer and Explanation is:
The correct answer is A. Buck’s traction.
Explanation:
Buck’s traction is a type of skin traction commonly used in the management of fractures of the lower extremities, including the femur, hip, and lower back. This method involves the application of a pulling force (traction) to the limb or affected area to stabilize fractures, reduce pain, and prevent complications associated with immobility, such as muscle atrophy and joint stiffness.
Mechanism of Action: In Buck’s traction, a padded harness or adhesive strips are applied to the skin over the affected area. A pulley system is then set up to apply weight (usually in the form of sandbags or weights) that pulls the leg in a straight line. The pulling force is directed along the line of the limb, creating counter traction through the patient’s body weight. This helps maintain the correct alignment of fractured bones, which is essential for proper healing.
Indications: Buck’s traction is particularly beneficial in cases where immediate surgical intervention is not possible. It is often used in cases of hip fractures or femoral shaft fractures. The traction helps relieve muscle spasms and reduces pain by minimizing movement at the fracture site. It can also facilitate better positioning for patients who are at risk for pressure sores due to prolonged bed rest.
Limitations: While effective, Buck’s traction is not without limitations. The skin can become irritated or damaged due to the constant pressure from the traction apparatus. Additionally, it is a temporary measure; once the patient is stable, definitive treatment options such as surgical fixation may be necessary. Regular assessment of circulation, skin integrity, and the effectiveness of the traction is crucial to avoid complications.
In summary, Buck’s traction is a vital tool in managing lower extremity fractures, providing stabilization and comfort until further treatment can be administered.
