A sprain is a stretch and/or tear of a ligament. A ligament is the fibrous band of connective tissue that joins two bones together. Ligaments stabilize and support the body's joints. For example, ligaments in the knee connect the upper leg with the lower leg, enabling people to walk and run.
A sprain is caused by direct or indirect trauma that creates a pulling force on the ligaments holding a joint in its proper position. This force may overstretch the ligament and cause minor partial small tears in the ligament or, in severe cases, full rupture the ligament. Typically, this injury occurs when an individual falls and twists the foot and/or ankle in an abnormal fashion. Symptoms of a sprain include: pain, bruising, swelling, and inflammation. The individual oftentimes feels a tear or pop in the joint. In severe cases this may make the joint nonfunctional. In other cases, where the sprain partially tears the ligament, some swelling may occur.
A strain is an injury of a muscle or tendon. Tendons are fibrous cords of tissue that attach muscles to bone.
Chronic strains are the result of prolonged, repetitive movements of muscles and tendons. Insufficient breaks during intensive training oftentimes lead to a strain. Symptoms of a strain include pain, muscle spasm, muscle weakness, swelling, inflammation, and cramping. In severe strains, the muscle and/or tendon are partially or completely ruptured, often incapacitating the individual.
There is no way to make yourself immune to sprains and strains, but proper stretching, appropriate footwear and warming up before engaging in physical activity will help alleviate these potential problems. If you have pain not responding to rest, ice, and over-the-counter medicines or if you suspect a serious injury, call our office to be seen for evaluation and appropriate treatment to ensure that more serious complications do not occur.
