Final answer:
An injury involving overstretched and torn ligaments is called a sprain. A high ankle sprain, which affects the tibia and fibula near the ankle joint, is a specific type of this injury. The severity of pain and treatment required can vary based on the injury's extent.
Step-by-step explanation:
If a patient has an injury that involves overstretched and torn ligaments, the injury is known as a sprain. These injuries usually occur when a joint is twisted or bent too far, such as in an ankle sprain, which is a common type of sprain. The ligaments, which are tough bands of connective tissue that connect bones and stabilize joints, are damaged when stretched beyond their limit or torn.
An example of a severe type of sprain is a high ankle sprain, which affects the ligaments connecting the tibia and fibula near the ankle joint, typically involved in a syndesmosis type of joint. The severity of a sprain can vary, causing different levels of pain, swelling, and immobilization, depending on the extent to which the ligaments are injured. Treatment for sprains often includes rest, ice, compression, elevation (RICE), and in more severe cases, surgery may be needed.
