Hamstring Strains and Tears

A hamstring strain can be a pull, a partial tear, or a complete tear. Muscle strains are graded according to their severity. A grade 1 strain is mild and usually heals readily; a grade 3 strain is a complete tear of the muscle that may take months to heal.

Most hamstring injuries occur in the thick, central part of the muscle or where the muscle fibers join tendon fibers. In the most severe hamstring injuries, the tendon tears completely away from the bone. It may even pull a piece of bone away with it. This is called an avulsion injury.

Elbow Injuries in Throwing

Overhand throwing places extremely high stresses on the elbow. In baseball pitchers and other throwing athletes, these high stresses are repeated many times and can lead to serious overuse injury.

Unlike an acute injury that results from a fall or collision with another player, an overuse injury occurs gradually over time. In many cases, overuse injuries develop when an athletic movement is repeated often during single periods of play, and when these periods of play — games, practices — are so frequent that the body does not have enough time to rest and heal.

Although throwing injuries in the elbow most commonly occur in pitchers, they can be seen in any athlete who participates in repetitive overhand throwing.

Shoulder Injuries in Throwing

Overhand throwing places extremely high stresses on the shoulder, specifically to the anatomy that keeps the shoulder stable. In throwing athletes, these high stresses are repeated many times and can lead to a wide range of overuse injuries.

Although throwing injuries in the shoulder most commonly occur in baseball pitchers, they can be seen in any athlete who participates in sports that require repetitive overhand motions, such as volleyball, tennis, and some track and field events.

Common Knee Injuries

Your knee is made up of many important structures, any of which can be injured. The most common knee injuries include fractures around the knee, dislocation, and sprains and tears of soft tissues, like ligaments. In many cases, injuries involve more than one structure in the knee.

Pain and swelling are the most common signs of knee injury. In addition, your knee may catch or lock up. Many knee injuries cause instability — the feeling that your knee is giving way.

Sprained Ankles

An ankle sprain occurs when the strong ligaments that support the ankle stretch beyond their limits and tear. Ankle sprains are common injuries that occur among people of all ages. They range from mild to severe, depending upon how much damage there is to the ligaments.

Most sprains are minor injuries that heal with home treatments like rest and applying ice. However, if your ankle is very swollen and painful to walk on — or if you are having trouble putting weight on your ankle at all, be sure to see your doctor.

Without proper treatment and rehabilitation, a more severe sprain can weaken your ankle—making it more likely that you will injure it again. Repeated ankle sprains can lead to long-term problems, including chronic ankle pain, arthritis, and ongoing instability.
