Final answer:
The most efficient method of immobilizing an injured ankle depends on the severity and type of injury. Most ankle sprains can be treated using the RICE technique. More severe injuries involving ligament tears or bone fractures may require surgery.
Step-by-step explanation:
The most efficient method of immobilizing an injured ankle depends on the severity and type of injury. For most ankle sprains, the RICE technique is typically used which includes rest, ice, compression, and elevation. A brace or cast may be used to reduce joint mobility during the healing process.
For more severe injuries involving ligament tears or bone fractures, surgery may be required. In these cases, a short spine board or traction splint may be used to immobilize the ankle during transport to the hospital.
It is essential to consult with a healthcare professional for an accurate assessment and recommendation for immobilizing an injured ankle.
