There also continues to be much controversy surrounding how to use splinting and the usefulness of rest in the treatment of tenosynovitis. On the basis of descriptive studies it can be said that tenosynovitis mostly affects the wrist and hand and more commonly the extensor tendon of the right/dominant hand. It is suggested that tenosynovitis occurs more commonly in females and the peak incidence is in the 35-40 years age group. Common opinions regarding causative factors are work related, infections and manifestations of diseases, Treatment of tenosynovitis mostly lies in rest and splinting and some suggest that electrotherapy and diathermy may help, If conservative treatment fails, many advocate surgery.
