Lateral epicondylitis

Also known as “Tennis Elbow”. The muscles of the forearm that allow you extend the wrist and the fingers attach to the part of a bone just outside of the elbow called the lateral epicondyle (lateral meaning “outside”; epi meaning above; “condyle” meaning knuckle – so “lateral epicondyle” means the place above the knuckle on the outside of the elbow).  When these muscles or their tendons become inflamed or torn it may cause pain.  Patients often complain of pain when pinching or gripping, or when extending the wrist – all things done when playing tennis – hence the name “tennis elbow.”
