The surgeon will cut the sheath that is restricting the tendon.
Triggering is predictably resolved by a relatively simple surgical procedure under local anesthesia. Most specialists recommend no more than 3 injections because corticosteroids can weaken the tendon and there is a possibility of tendon rupture. If triggering persists 2 months after injection, a second injection can be considered. Steroid injection is not effective in people with Type 1 diabetes. Injection of the tendon sheath with a corticosteroid is effective over weeks to months in more than half of people. The role of sonographic guidance is therefore debatable. There is evidence that the steroid does not need to enter the sheath. The infiltration of the affected site is straightforward using standard anatomic landmarks. Treatment consists of injection of a corticosteroid such as methylprednisolone often combined with a local anesthetic ( lidocaine) at the A1 pulley in the palm. See: ĭepending on the number of affected digits and the clinical severity of the condition, Corticosteroid injections can cure trigger digits. Post operative photo of trigger finger release surgery in a diabetic patient. Upon waking, the affected person may have to force the triggered fingers open with their other hand. The triggering more often occurs while gripping an object firmly or during sleep when the palm of the subject’s hand remains closed for an extended period of time. It is most common in the thumb and ring finger. More than one finger may be affected at a time. The relationship of trigger finger to work activities is debatable and there are arguments for and against a relationship to hand use with no experimental evidence supporting a relationship.ĭiagnosis is made on interview and physical examination. Some speculate that repetitive forceful use of a digit leads to narrowing of the fibrous digital sheath in which it runs, but there is little scientific data to support this theory. However, recent publications indicate that diabetes and high blood sugar levels increases the risk of developing trigger finger. The vast majority of trigger digits are idiopathic, meaning there is no known cause. It is important to distinguish association and causation. There is some evidence that idiopathic trigger finger behaves differently in people with diabetes.

There may be tenderness in the palm of the hand near the last skin crease (distal palmar crease). Symptoms include catching or locking of the involved finger when it is forcefully flexed. Splinting immobilization of the finger may or may not be disease modifying. Treatment options that are disease modifying include steroid injections and surgery. Trigger digits can resolve without treatment. Diagnosis is typically based on symptoms and signs after excluding other possible causes. Mucoid degeneration is when fibrous tissue such as tendon has less organized collagen, more abundant extra-cellular matrix, and changes in the cells (fibrocytes) to act and look more like cartilage cells (chondroid metaplasia). While often referred to as a type of stenosing tenosynovitis (which implies inflammation) the pathology is mucoid degeneration. The pathophysiology is enlargement of the flexor tendon and the A1 pulley of the tendon sheath. There may be an association with diabetes. The problem is generally idiopathic (no known cause). The ring finger and thumb are most commonly affected. The name "trigger finger" may refer to the motion of "catching" like a trigger on a gun.
