Abstract

We investigated whether incision type affects scar quality or outcome following trigger finger release. Our primary and secondary hypotheses were that transverse and longitudinal incision types yield similar scar quality and functional improvement. Digits undergoing trigger finger release at the participating hospitals were randomized to receive transverse or longitudinal incisions. The Patient Scar Assessment Scale, Observer Scar Assessment Scale, and the Disabilities of the Arm, Shoulder and Hand score were collected at 8 and 54weeks postoperatively. Of 86 randomized patients, 67 patients (71%) had followed-up at 54weeks postoperatively. We found no significant differences in above three assessments between the incisions at either time-point. Among patients receiving both incision types for multiple simultaneous trigger finger release, there were no significant differences in Patient Scar Assessment Scale or Observer Scar Assessment Scale scores. We found no significant difference in the scar quality and improvement in patient-reported disability with transverse or longitudinal incisions for trigger finger release. Level of evidence: II.
