The De Quervain's disease, also known as tenosynovitis, tendinitis or DeQuervain syndrome is a pathology that causes pain in the wrist and difficulty in using the hand, mainly the thumb. The disease was described by Fritz de Quervain in 1895. The pain is caused by the inflammation of the synovia sheat through wich two of the tendons that move the thumb are passing: abductor policis longus and short extensor of the thumb. They are situated right above the radial styloid. As clinical investigation the Finkelstein test is specific https://youtu.be/VniQzPHqtSk : the thumb is held in the fist, and the hand is tilted ulnary. The test is positive if pain occurs in the radial styloid. In case of chronic or drug-resistant disease, the surgical treatment is advised. It consists of releaving the tension between tendons and their sheath (synovium). The intervention is performed under local anesthesia and the recovery is quick.
