TRIGGER Trial

 

Trigger finger is one of the most common conditions seen by hand surgeons. Different non-operative treatments (e.g. physiotherapy, splinting and NSAIDs) have been described with little evidence to support the usage. The mainstay of non-operative treatment remains intermediate-acting steroid injection with or without a local anesthetic added. Operative management is by release of the A1 pulley, either percutaneously or with open surgery.

A recent systematic review showed moderate evidence that steroid injections are an effective initial treatment for trigger fingers. However, this evidence is based on two small studies of poor quality with a short follow-up of just four months. There is high quality evidence that trigger digits can be managed safely by open or percutaneous surgical release, but there are only 3 RCTs with several shortcomings comparing steroid injection with surgery.

We propose a large, international, multicenter, randomized controlled trial to compare steroid injection and surgery in treating trigger fingers with follow-up of one year. At the end of this study we should be able to make an evidence-based recommendation on how to treat a patient with a trigger finger.

Population: Adults with ≥ 1 trigger fingers

Intervention: Surgical release using surgeon’s preferred technique (open or percutaneous)

Control: ≥ 1 injections with steroid injection (steroid of choice, with or without local anesthetic added)

Outcome:

  • Primary outcome: resolution of triggering
  • Secondary outcome: level of pain, hand function (PROM), costs and complications
  • Subgroup analysis: type of surgery, type of injection, thumb vs long digits, diabetes, rheumatoid arthritis
  • Follow-up: 6 and 12 months

The project will use similar methodology to the WIRE Study. Collaborators will submit a ‘denominator’ list of all eligible hand surgeons and therapists and be expected to get a high response rate. This will lead to Pubmed citation as a collaborator.
