Trigger finger is a condition where there is a size disparity between the flexor tendons and the surrounding pulley system at the first annular pulley (the A1 pulley). This causes the tendon to catch on the pulley as it attempts to glide through unless enough pressure is developed to allow it to forcefully move through the pulley. The exact cause of trigger finger is not always clear, but it is often attributed to overuse injuries or repetitive motions.

De Quervain’s Tenosynovitis is a painful condition that affects the tendons at the base of the radial (thumb) side of the wrist. De Quervain’s Tenosynovitis occurs when the tendons at the base of the wrist become irritated or restricted. This condition is often linked to activities requiring repeated wrist movements or grasping including gardening, tennis, texting, golf, hammering, and rock climbing.
