Although it is typically referred to as a single joint, the ankle is actually two joints:
The true ankle joint, which is composed of three bones:
The ends of the bones are covered by articular cartilage. The space in the joint is lined with a thin membrane called the synovium, which cushions the joint and secretes a lubricating fluid, called synovial fluid.
Several strong bands of connective tissue, called ligaments, hold the bones of the ankles together. A number of tendons run through the ankle, attaching muscles of the lower leg to the bones of the foot and ankle.
Here is what you need to know about sprained ankles and some other common ankle injuries.
The most common ankle injury, sprains occur when the ligaments that normally support the ankle become stretched beyond their normal range. This happens when the foot twists, turns or rolls as a result of fall or misstep. Doctors grade sprains on a scale of one to three, based on the severity of the damage, with one representing slight stretching and some damage to the ligament fibers and three representing a complete tear of the ligament.
Whether you have an acute injury or chronic arthritis, medications don’t always relieve pain completely. And if you have surgery, you’ll likely need some help getting around while you heal. At times when you need extra help with pain relief or mobility, here are some techniques and devices worth trying.
