We retrospectively reviewed 1305 open-surgery for idiopathic trigger finger performed by 4 senior hand surgeons between 2014 and 2016.
Medical records and a telephone interview made with a minimum follow-up of 1 year were used to identify the recurrent rate of triggering and other complications.
This retrospective study let us note that 169 fingers (13%) required simultaneous release of the A1-A2 pulleys because the sectioning of the A1 pulley alone did not lead to complete free sliding of the tendons. We did not record any bowstring complication and we ascribe this to both surgery and bandaging technique. Overall rate of complication was 11.8% and relapse triggering or permanent proximal interphalangeal joint flexion (PPIJF) were among them; notably, however, they occurred only in patients where the A2 pulley was not sectioned.
Is possible to reduce the percentage of relapse triggering or PPIJF after trigger finger surgery, by performing that combined A1-A2 pulley release.
