Description

Patients who were diagnosed with moderate CTS by EMG after clinically diagnosing CTS in our hospital's PTR clinic will be included in our study. At the beginning of the study, based on the study conducted by Wu et al. (1) who evaluated the effectiveness of dextrose prolotherapy in the treatment of patients diagnosed with carpal tunnel syndrome, the minimum number of patients required for each group was determined as 20 with a mean pain VAS change of 20%, a significance level of 0.05 and a power analysis of 95%. Considering that there may be a 20% loss during the study, it was decided to include a total of 72 patients, at least 24 patients for each group.

Patients who meet the inclusion criteria and fill out the "Informed Volunteer Consent Form" will be numbered according to their application order to the PTR clinic and will be randomized into three groups of 24 people using the "Research Randomizer" computer program, with the first group being the Ozone Group (OG), the second group being the Dextrose Group (DG) and the third group being the Corticosteroid Group (SG). Initial evaluations of the participants will be made before the injection. Each patient will receive one session of perineural injection of 1 ml betamethasone dipropionate mixed with 1 ml physiological serum to the first group; 2 ml 5% dextrose to the second group; and 2 ml 10 pg/ml ozone to the third group. The solutions to be administered will be prepared by one person in syringes that are taped shut from the outside, and then applied with a 27-gauge needle by a specialist physician who has no role in the evaluation of the results of the randomization section, from the proximal entrance of the carpal tunnel (scaphoid-psiform plane) under ultrasound guidance. In addition, each patient will wear a wrist splint for 8 hours daily during the post-treatment follow-up period. Treatment follow-up evaluations will be evaluated blindly by another specialist physician who has no role in the randomization, outcome evaluation and injection.
