De Quervain's Tenosynovitis
(De Quervain’s Syndrome; De Quervain’s Disease; Washerwoman’s Sprain)
DefinitionDe Quervain's tenosynovitis is an irritation of tendons that run from the wrist to the thumb. These tendons pass through a tunnel-like tissue, called a sheath, at the wrist. The tunnel area can cause additional pressure and irritation on thickened or swollen tendons, making normal movements painful.
