This may be intermittent, and the patients may develop snapping or catching. The patients often have pain on the palmar aspect of the thumb and fingers. Some medical conditions such as rheumatoid arthritis and diabetes can be associated with an increased risk of trigger finger/thumb, and local trauma may be a precipitating cause, but often the etiology is unclear. This may lead to pain, catching or triggering, or the thumb or finger becoming stuck in a flexed or extended position. In stenosing tenosynovitis, the tendon sheath thickens, there may be inflammation of the tendon, and the tendons fail to glide through the tendon sheath in a smooth and painless fashion. The tendon sheath holds the tendons against the bone and adds mechanical advantage for the flexion of the thumb and fingers. The thumb has one flexor tendon, and each finger has two flexor tendons. Think of it as a rope going through a hose. When these tendons pass out into the thumb and fingers, they run through a tendon sheath or tube. The muscles on the palmar side of the forearm are connected to the fingers by long tendons or ropes. What is trigger finger/trigger thumb or stenosing tenosynovitis? The first is trigger finger/trigger thumb (stenosing tenosynovitis), and the second is De Quervain’s disease, or extensor tenosynovitis.
There are two common causes of hand pain which are seen on a frequent basis. Hand pain can be the result of trauma, arthritis, nerve compression, infections, tumors, and skin/circulatory disorders. This is an extremely broad topic which includes many conditions.
