We report a randomized trial of two skin incisions for carpal tunnel decompression, namely a standard incision and an ulnar L incision. We looked particularly at the resolution of local symptoms namely pillar pain and scar sensitivity. There were 47 patients in the trial. No difference was found in pillar pain between the two incisions, but one had a lower incidence of scar sensitivity. These results give a baseline for comparison of local postoperative symptoms following open release with those following endoscopic release.
