Epicondylitis (Tennis Elbow)
Tennis elbow, or lateral epicondylitis, is a painful condition of the elbow caused by overuse. Not surprisingly, playing tennis or other racquet sports can cause this condition. But several other sports and activities can also put you at risk.
Tennis elbow is an inflammation of the tendons that join the forearm muscles on the outside of the elbow. The forearm muscles and tendons become damaged from overuse. This leads to pain and tenderness on the outside of the elbow.
Cubital Tunnel Syndrome (Ulnar Nerve Entrapment)
Cubital Tunnel Syndrome occurs when the ulnar nerve in the arm becomes compressed. When this happens, the nerve does not function normally.
It is not known exactly what causes compression of the ulnar nerve. Some factors can make it more likely that the nerve will be compressed. These include: Prior fractures of the elbow, Bone spurs, Swelling of the elbow joint and cysts.
A direct blow to the inside of the elbow, leaning on the elbow for prolonged periods, or repetitive activity that requires a bent elbow can irritate the nerve if it is already compressed
Fractures (Radius, Ulna)
When you bend your elbow, you can easily feel its "tip," a bony prominence that extends from one of the lower arm bones (the ulna). That tip is called the olecranon (oh-lek'-rah-nun). It is positioned directly under the skin of the elbow, without much protection from muscles or other soft tissues. It can easily break if you experience a direct blow to the elbow or fall on a bent elbow.
