Clinical Trial Summary

This is a prospective, open-label, parallel-group, randomized controlled trial to evaluate the postoperative outcome after carpal tunnel release by using mini CTS releaser and open method with duration of 6 months estimated. The study hypothesis is that mini CTS releaser can offer similar functional outcomes to the open approach and avoid the complications of the open surgery.


Clinical Trial Description

The current study is the first clinical trial of carpal tunnel syndrome treated by using a device - novel mini CTS releaser. The functional outcome and objective outcome will be recorded to prove the hypothesis that mini CTS releaser can offer similar functional outcomes to the open approach and decrease the complication rate in comparison of the open surgery. When patients visit, the research physician confirms whether the eligibility criteria are met, and the physician verbally explains the research theme, purpose, and method of execution. After the patient's consent, he should sign the subject consent. At baseline recruitment, a standardized in-person interview will be conducted by trained and certified study personnel according to structured questionnaires to obtain information on socio-demographic characteristics, habits of tobacco and alcohol use, peripheral blood sample will be also collected from each participant. All of the operated patients underwent a complete personal medical history review, detailed physical examination, as well as routine hematological tests. Patients will be randomized 1:1 to mini CTS releaser group or to open release group. There will be 35 individuals in each treatment arm. The planned follow-up time will be scheduled. Safety outcomes including adverse events and changes around surgical wound and neurologic sign will be recorded. Patients will be carefully observed and if any abnormality is noted, appropriate measures will be instituted. The surgical materials used are all certified by the Ministry of Health and Welfare in Taiwan. The possible side effects, such as infections or inflammatory reactions that may occur after surgery, will be given antibiotics or other appropriate treatments in accordance with standard medical procedures. Data of baseline characteristics will be described using means with standard deviations (SDs) or medians and interquartile ranges (IQRs), or both for continuous variables and using frequencies (percentages) for categorical variables. Mean morphological measures (and changes) will be computed as averages across participants within each treatment group. Between-group baseline comparisons will be based on 2 independent two sample t test or Wilcoxon Mann-Whitney test for quantitative variables, and chi-square test or Fisher's exact test for categorical variables. P values less than 0.05 will be adjusted for multiple comparisons using Bonferroni correction. All statistical analyses will be performed using SAS software Version 9.4 (SAS Institute Inc., Cary, North Carolina). ;
