Stenosing tenosynovitis of the flexor tendon sheath of the digits of the hand results from a discrepancy between the diameter of the flexor tendon and its sheath at the A1 pulley. The treatment options for trigger digits include oral nonsteroidal anti-inflammatory drugs (NSAIDs) and local NSAID applications, splintage, steroid injection, and percutaneous and open release of the A1 pulley. Injectable NSAID is used intramuscularly and locally in other sites. The hypothesis is that an injectable NSAID is as effective as the traditionally used steroid injection in the treatment of trigger digit, based on Quinnell grading, and that the treatment works as well in patients with diabetes as in those without diabetes.
We compared the effectiveness of physiotherapy and corticosteroid injection treatment in the management of mild trigger fingers. Mild trigger fingers are those with mild crepitus, uneven finger movements and actively correctable triggering. This is a single-centred, prospective, block randomized study with 74 patients; 39 patients for steroid injection and 35 patients for physiotherapy. The study duration was from Jun 2009 until August 2010. Evaluation was done at 6 weeks, 3 months and 6 months post-treatment. At 3 months, the success rate (absence of pain and triggering) for those receiving steroid injection was 97.4% and physiotherapy 68.6%. The group receiving steroid injection also had lower pain score, higher rate of satisfaction, stronger grip strength and early recovery to near normal function (findings were all significant, p triggering). Those who received corticosteroid injections had a significant recurrence rate of pain but not triggering. The physiotherapy group had no recurrence of pain or triggering due to the type of triggering responsive to physiotherapy or possibly due to awareness of physiotherapy exercises. Perhaps they were able to institute self-treatment on early onset of symptoms of trigger fingers. We conclude that corticosteroid injection has a better outcome compared to physiotherapy in the treatment of mild trigger fingers but physiotherapy may have a role in prevention of recurrence.
