Lateral Elbow Pain
The most common term for pain on the outside of the elbow is Tennis Elbow (Llateral Epicondylitis). However there are a number of other causes of lateral elbow pain which should be considered as well as acute elbow injuries such as ligament sprains and fractures. Other potential causes of pain on the outside of the elbow include referred pain, radial tunnel syndrome, synovitis, bursitis and osteochondritis dissecans.
Tennis Elbow is a general term used to describe pain on the outside of the elbow. The most common causes is inflammation or degeneration of the tendon of the wrist extensor muscles as they insert into the elbow. It is also known as lateral epicondylitis or extensor tendinopathy.
Radial tunnel syndrome or radial nerve entrapment as it is sometimes called is when the radial nerve gets compressed or restricted in the tunnel it passes through.
Osteochondritis Dissecans is a fragmentation of the cartilage and sometimes the underlying bone within a joint. This is common in adolescents as the ends of the bones are not yet fully hardened.
Synovitis of the elbow joint is inflammation of the synovial membrane which surrounds the joint becomes inflamed.
Radiohumeral bursitis can also give similar symptoms to tennis elbow. This is inflammation of a bursa or small sack of fluid which sits between the tendon and the bone to help lubricate it.
