              Introduction : Carpal tunnel syndrome(CTS) is the most common compressive neuropathy of the median nerve in patientofThungsong hospital.The standard surgical treatment incarpal tunnel syndromegives results of long surgical scar, long time to return to work and also scar pain and pillar pain. Many new techniques were introduced, also the PSU retractor, to help in mini-incision surgical treatment. To minimize the wound complication and better surgical outcome.
              Objectives : To report the result of surgical treatment carpal tunnel syndrome with mini-incision using PSU retractor in 5-year experience.
              Materials and methods: The study was designed as prospective nonrandomizedclinical trial. The patients who were diagnosed with carpal tunnel
syndrome visited at Orthopedic out-patient department of Thungsong hospital between January 2011–December 2015 were asked to participate in this study and surgery with mini-incision usingPSU Retractor technique.
They have to has the follow up at least 2 times : 1 week and 1 month postoperation. The data about satisfactory, VAS scores, Thai Boston score,
and time to return to work has to be recorded.
              Results : 95 patients were enrolled and surgical treatment of carpal tunnel syndrome by using mini-incision with PSU retractor. There were 9 males and 86 females. The average age was 52.48 year olds, the average duration of symptoms was 6.85 months. The average incisionsize was 18.95 millimetersand the average operative time was 18.51 minutes. At the post operativetime of 1 month follow up,the average time to return to work was 7.02 days, VAS score1.21 and the average satisfactionwas 9.56. The complications of using mini-incision using PSU retractor were pillar pain wound dehiscence and recurrent symptom.
              Conclusions : The surgical treatment of carpal tunnel syndrome by using mini-incision with PSU retractor showed the better outcome, including
minimized the complication rate and satisfied with the operative result.
