Which method is suggested for splinting a knee fracture?

Using available soft materials like pillows is suggested for splinting a knee fracture because this method helps provide adequate support and cushioning while allowing for comfort during transport. Soft materials can conform to the shape of the injured area, reducing the risk of further injury or discomfort for the patient. This technique is particularly useful in emergency situations where rigid splints may not be immediately available. Soft materials also allow for some degree of flexibility, which can be beneficial in accommodating swelling that often accompanies fractures.

In contrast, the use of a movable splint technique could be less effective in securing the position of the knee joint, as the primary goal in splinting a fracture is to immobilize the joint to prevent movement that could exacerbate the injury. Hard plastic alone might not provide adequate comfort or support. While a rigid metal cast is effective for long-term immobilization, it is not practical in acute situations and can cause additional discomfort.
