Of all human diseases and disabilities, the self inflicted ones are of especial interest because the etiology is usually so clear. This is especially true of the occupational diseases. When the cause of a disease is found, the treatment is usually outlined and becomes more or less specific; however, the condition under discussion is a notable exception.
Epicondylitis humeri, better known as tennis elbow, and also known as epicondylalgia and radiohumeral bursitis, has been a subject for investigation since 1896 at least, when Bernhardt1 published a paper on a little known form of occupational neuralgia.
By epicondylitis humeri we mean a well defined clinical entity with marked pain and tenderness about the elbow, occurring after a great muscular exertion or some continuous labor, the symptoms following such games as tennis, polo, baseball and squash or such occupations as pressing clothes with heavy irons, typewriting, bricklaying, carpentry or painting.
