Tenosynovitis is a painful condition that impacts the protective sheath surrounding a tendon. This condition, similar to tendinitis which affects the tendon itself, is believed to be caused by repetitive motion or strain injury. It is commonly seen in middle-aged individuals who engage in physical activity or have occupations that involve repetitive movements. The main cause of tenosynovitis is the roughening or inflammation of the synovium, the fluid-filled sheath that surrounds the tendon, as a result of overuse.
Two Varieties of Tenosynovitis
There are two distinct variations of tenosynovitis. The first one is known as De Quervain’s tenosynovitis, which involves inflammation of the tendon sheath located on the side of the hand, specifically at the base of the thumb. This form of tenosynovitis typically occurs due to repetitive stress and strain on the tendons in that area. Individuals with De Quervain’s tenosynovitis often experience intense pain when moving their thumb. The second type is called stenosing stenosynovitis, commonly referred to as Trigger Finger. It primarily affects the middle finger or ring finger, although the thumb may also be affected.
De Quervain’s Tenosynovitis: A Painful Condition Affecting the Thumb
De Quervain’s tenosynovitis is a debilitating condition that causes immense pain when performing simple tasks such as turning your wrist, grasping objects, or making a fist. This condition, also known as thumb tendinitis, is commonly caused by repetitive hand or wrist movements that strain the tendons in the thumb.
