Steroid injection is not effective in people with Type 1 diabetes. If triggering persists 2 months after injection, a second injection can be considered. Most specialists recommend no more than 3 injections because corticosteroids can weaken the tendon and there is a possibility of tendon rupture. Triggering is predictably resolved by a relatively simple surgical procedure under local anesthesia. The surgeon will cut the sheath that is restricting the tendon. The patient should be awake in order to confirm adequate release. On occasion, triggering does not resolve until a slip of the FDS (Flexor digitorum superficialis) tendon is resected. One study suggests that the most cost-effective treatment is up to two corticosteroid injections followed by open release of the first annular pulley. Choosing surgery immediately is an option and can be affordable if done in the office under local anesthesia. Surgery
Trigger digits can be released percutaneously using a needle. This is not used for the thumb where the digital reves are at greater risk. References
