A sprain is the stretching or tearing of ligaments. Ligaments connect adjacent bones and provide stability to a joint. An ankle sprain is a common injury that occurs when you suddenly fall or twist the ankle joint, or when you land your foot in an awkward position after a jump. Most commonly, it occurs when you participate in sports, or jump or run on a surface that is irregular.
The joints of the ankle are held in place and stabilized by strong bands of tissue called ligaments. Ankle instability is a chronic condition characterized by a recurrent slipping of the outer side of the ankle. It usually results from repeated ankle sprains, which are injuries to the ligaments. Ankle instability is generally noticed when you move your ankle joint but can also occur while standing
Osteochondral Injuries of the Ankle
The ankle joint is formed by the articulation of the end of the tibia and fibula (shinbones) with the talus (heel bone). Osteochondral injuries, also called osteochondritis dissecans, are injuries to the talus bone. It is characterized by damage to the bone as well as the cartilage covering it. Sometimes, the lower end of the tibia or shinbone may also be affected.
Ankle Ligament Injury
Ligaments are made up of elastic tissues that interconnect bones to one another. They bind the joint together, providing stability and support to the joint. The ligaments protect the ankle joint from abnormal rotation and stabilize the joint during movement.
