The Fate of Injected Trigger Fingers

Patients who were scheduled for surgical release of their trigger fingers underwent an injection of the involved tendon sheath prior to surgery. In thirty-six patients the injection of methylene blue was undertaken in a proximal-distal direction and in forty-three the direction of the injection was reversed. The success rate of the injections was 61 per cent. in the proximal distal group and 37 per cent in the second group. There was no significant statistical difference with regard to age, but duration of the disorder and mode of injection regarding the different fingers did have statistical significance.
