How effective are corticosteroid injections for trigger finger (stenosing tenosynovitis) in adults?
The methodological quality of the 2 studies included was poor and there were some flaws in the quality of reporting. The 2 trials were performed in the setting of secondary care and generalisability to other settings (eg, primary care) remains to be established.
Trigger finger (stenosing tenosynovitis) is a disease of the tendons of the hand leading to triggering, snapping or locking of affected fingers, dysfunction and pain. The lifetime prevalence of trigger finger among a group of non-diabetics above the age of 30 years has been estimated at 2.2%. Available treatments include local injection with corticosteroids, surgery or splinting.
