Testing essentially consists of one or two tests. The Tinel’s test has to do with the exquisite sensitivity of any nerve at an injury point. A nerve that is injured will fire an ectopic focus (a lightening bolt of electricity) down to the end of nerve when stimulated. Percussion of the injury area will elicit this “lightening bolt”. In the case of tarsal tunnel syndrome, the injury point is where the nerve wraps around the ankle. A positive test will cause an electrical “zap” into the foot with percussion of the nerve at the ankle.
Viscosupplementation is a minimally invasive treatment option used to relieve knee pain and inflammation caused by osteoarthritis (OA). In this procedure, a thick gel-like liquid called hyaluronic acid (also called hyaluron and hyaluronate) is injected into the affected knee. Since hyaluronic acid is a naturally occurring substance found in the synovial (joint) fluid, viscosupplementation acts as a lubricant to enable bones to move smoothly over each other and as a shock absorber for joint loads. This medication only affects the targeted area and does not usually cause side effects.
