Elbow joint connects three bones (Humerus, Ulna, Radius), muscles, ligaments, and links. The elbow joint must have a certain mobility and strength. There are three types of elbow injuries that can happen in volleyball: tennis elbow, golfers elbow and throwers elbow. Volleyball players during training use different throws and movements that are similar to these sports, while serving and spike have similar kinematic structure.
Tennis elbow is an inflammation of the tendon that connects the extensor muscles with external epikondilom. These are the long muscles on the outer side of the forearm that help to open up and correct the hand and wrist. The mechanism of injury is related to the muscles that are annexed to the lateral humeral epikondilus: m extensor carpi radialis longus and brevis, m. extensor carpi ulnaris, m. extensor digitorum, m. extensor digiti minimi, m. Supinator and m. Anconeus.
Throwers elbow injury occurs when there is damage to the bones, muscles, tendons and ligaments around the elbow joint and forearm. The structures on the medial side of the elbow to stretch because of the throwing movement, and at the same time compresses the structures on the lateral side of the elbow.
This injury can cause movements restrictions, pain, formation of scar tissue, bone spurs. If untreated, muscles and nerves can cut off the blood flow because of so much pressure that causes this injury and pinch the nerves responsible for controlling the muscles in the forearm.
There are a number of preventative techniques that will help to prevent elbow injury. Some of them are correct warm up, flexible muscles and tendons, strengthening and conditioning the muscles of the forearm and wrist.
