Your hands and wrists are essential tools that allow you to work, play and perform everyday activities. How well the hand and wrist interact depends on the integrity and function of the ligaments, tendons, muscles, joints and bones.
Wrist tendonitis can affect upper extremity function, causing disruptions at home and work and negatively impacting quality of life.
The human hand itself is very complex and delicate in structure.
Wrist (De Quervain’s) tendinosis occurs when the tendons around the base of the thumb are irritated or constricted.
The word “tendinosis” refers to a swelling of the tendons. Swelling of the tendons, and the tendon sheath, can cause pain and tenderness along the thumb side of the wrist.
This is particularly noticeable when forming a fist, grasping or gripping something, or when turning the wrist.
