Efficacy of cortisone injection in treatment of trigger fingers and thumbs.

One hundred eight trigger fingers and thumbs in 74 consecutive patients were treated by injections of triamcinalone and followed for an average of 3 1/2 years. Minimum follow-up was 1 year. Eighty four percent of trigger fingers and 92% of trigger thumbs were cured with a single injection, and a repeat injection for treatment of recurrent symptoms raised these figures to 91% and 97%, respectively. All injections were done by one physician. There were no complications. We conclude that intrasynovial injection of a steroid compound is the appropriate initial treatment for trigger fingers and thumbs.
