Investigating the effect of tenosynectomy on the improvement of symptoms and fine movements of fingers in patients with carpal tunnel syndrome after open surgery

A clinical trial with a control group, with parallel groups, a blind strain, block randomization, on 60 patients, for better randomization, web software will be used to prepare a randomization list for both types of treatment in each The block generates random permutations

patients referred to the orthopedic clinic and Hazrat Wali Asr Arak Hospital, whose diagnosis of carpal tunnel syndrome was confirmed after examination and confirmation of the diagnosis by an orthopedic specialist. Patients are divided into 2 intervention and control groups, each group containing 30 people diagnosed with carpal tunnel syndrome according to the inclusion criteria, and patients are randomly assigned to the study. In this study, the patient is blinded. The study is of a blind type. Informed consent is obtained from the patient that one of the surgical procedures will be performed without and with tenosinectomy. But in the end, the patient will not understand the type of surgical technique.

confirmation of electrodiagnostic tests, consent to participate in the study, absence of thenar atrophy, absence of old fractures in the forearm and wrist, absence of any congenital deformity in the forearm and wrist area. Exclusion criteria: patient's failure to return, patient's lack of consent to continue the study, patient's lack of cooperation

Patients with carpal tunnel syndrome undergo tenosinectomy, which means removing the tendon sheath.In the control group, patients undergoing carpal tunnel syndrome surgery are operated without tenosynovectomy, i.e. without removing the tendon sheath.

Severity of symptoms, subtle movements of fingers

In this study, due to the presence of two types of surgical techniques, the block randomization method will be used. The randomization unit is the person. According to the sample size, blocks with a capacity of 4 units were considered. By assigning the letter A to the intervention group and the letter B to the control group, there are six states AABB, BBAA, BABA, ABBA, BAAB and ABAB. Then it is randomly selected from among these situations and a list equal to the sample size is prepared for patients before the start of the study. For better randomization, the web software will be used to prepare the randomization list, which creates random permutations for both types of treatment in each block, and according to the change of permutations in each block, concealment is also observed. During the implementation of the study, the predictability of the treatment for each patient is reduced by the researcher.
