Various sports injuries have been reported. Researchers always try to find a link or connection to explain what's happening. When it comes to elbow problems, there's no doubt the number is on the rise. Before organized baseball, many of these conditions never even
existed.

Doctors from a clinic specializing in shoulder and elbow problems offer a guess on this one. In younger children, the medial epicondyle (boney bump on the inside of the elbow) isn't fully formed yet. There's a slight separation between the epicondyle and the
main bone. This allows for bone to fill in as the child grows.

It's a term used to describe injury to the inside of the elbow. It happens so often in pre-teens and young teens from pitching the name has caught on. When the pitcher throws the ball, the elbow is in a position called valgus. This means the angle of the elbow puts the force on the inside edge of the elbow.

The quadriceps tendon attaches the group of strong muscles in the front of the thigh (the quadriceps) to the shinbone (the tibia). Inflammation of this tendon is known as jumper's knee. Jumper's knee is common in athletes who play sports that involve jumping and stop-and-go running. Treatment is fairly simple, and the outcomes are generally good.

Sudden weakness in any athlete is cause for concern. When a 15-year old girl developed severe weakness in both arms after swimming, a medical exam was needed. There weren't any problems at rest, just during swimming or weight-training.

Parents and coaches involved in youth baseball in the United States have asked for help. Arm problems in pitchers are all too common. The athlete's elbow and shoulder are structurally the same as the nonathlete's. The difference is the stress of training and the demands of regular and intense competition. Using the same arm over and over can cause damage to the ligaments, tendons, nerves, and muscles.
