	Trigger Thumb - My Child Has - Children's Hospital Boston
		Trigger thumb refers to a thumb that clicks, catches, or locks as the tip of the thumb moves from a flexed (bent) to extended (straight) position.
		Trigger thumbs are caused by a size mismatch between the flexor tendon of the thumb and the A1 pulley, a fibrous band under which the tendon normally glides.
		Trigger thumbs are diagnosed by the treating physician after a thorough medical history and careful physical examination.

	Trigger finger
		Trigger finger is the popular name of stenosing tenosynovitis, a painful condition in which a finger or thumb locks when it is bent (flexed) or straightened (extended).
		Trigger finger is often an overuse injury because of repetitive or frequent movement of the fingers.
		Trigger finger may happen because a person performs the same manipulation over and over on a job, from squeezing and gripping during a weekend of heavy pruning and gardening, or from such hobbies as playing a musical instrument or crocheting.

		The roles of overuse and trauma in trigger thumb are controversial, although the condition does have a predilection for the dominant hand.
		Trigger thumb in patients with rheumatoid arthritis or chronic infection is due to diffuse proliferation of tenosynovium within the tendon sheath.

	ASSH \| Trigger Finger Stenosing Tenosynovitis
		Stenosing tenosynovitis, commonly known as “trigger finger” or “trigger thumb”, involves the pulleys and tendons in the hand that bend the fingers.
		Trigger finger/thumb occurs when the pulley at the base of the finger becomes too thick and constricting around the tendon, making it hard for the tendon to move freely through the pulley.
		When the finger begins to trigger or lock, the patient may think the problem is at the middle knuckle of the finger or the tip knuckle of the thumb, since the tendon that is sticking is the one that moves these joints.

		Trigger thumb is a condition where the thumb is locked in the flexed position at the Interphalangeal Joint (IP joint).
		Trigger thumb is due to thickening and constriction of the fibrous flexor sheath the surrounds the Flexor pollicis tendon at the base of the thumb.
		In cases where the thumb is locked in acute flexion and does not allow any extension, surgical release of the fibrous flexor sheath is indicated by age 2 to prevent permanent contracture.

	Trigger Finger Central
		Trigger finger is a common disorder of the hand which causes a painful snapping or locking of the fingers or thumb.
		Straightening the finger or thumb may require using the non-affected hand to actually pull the finger back into an extended position, causing another painful snap as the swollen portion of the tendon passes back through the sheath.
		Symptoms of trigger finger may also be associated with conditions such as rheumatoid arthritis, gout, or metabolic disorders such as diabetes that produce changes in connective tissues and synovium.

		Stenosing tenosynovitis of the flexor tendons of the hand, better known as trigger finger and trigger thumb, is a common condition in the hand.
		Patients with this condition present with symptoms of pain and discomfort at the metacarpophalangeal joint crease of the thumb and finger initially, and commonly progress to painful snapping, catching or triggering in these digits during thumb and finger motion.
		Palpating these areas during flexion and extension of the thumb and fingers will usually show enlargement of the flexor tendon which is called a flexor tendon nodule.
