Tennis elbow: a biomechanical approach.

may say that I have found no benefit from treatment hitherto: and you only have to drive a pulling horse, draw a tooth or even handle the bottles in surgery to find the full force of the annoyance.&dquo; The condition and the efficacy of treatment have not materially improved in one hundred years. The etiology of &dquo;tennis elbow&dquo; has been given as: prominence of the radial head,12 radial humeral bursitis,15 synovial fringes, various nerve entrapments,2 radial tunnel syndrome,’3 tendinitis, periostitis, tears of the conjoined tendon, neuritis,’ abnormalities of the obicular ligament or a combination of the above. Recommended treatment has included local infiltration, rest, manipulation or surgery. This study was undertaken to record the function of the extensor muscle mass during tennis stroke production in hopes of eliciting that stress responsible for the production of lateral epicondylitis. It was also hoped that guide-lines for the proper selection of tennis equipment might be established.
