IRCT20230222057488N1 IRCT 2023-02-26 Iran University of Medical Sciences Investigating the effect of percutaneous needle method in the repair of trigger finger Evaluation of the effect of percutaneous needle on A1 poly release in trigger finger 2023-04-21 anticipated 20 Complete https://irct.ir/trial/68764 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: We have 10 numbers of code number 1 and 10 numbers of code number 2, which we put in an envelope and draw lots for each patient before the operation, using a simple random method. Code number one is related to treatment with pink needle and code number two is green needle, Blinding description: We throw 20 pieces of paper into the envelope by a simple random method. We write code number 1 on 10 numbers and code number 2 on the other 10 numbers, and before the operation we take out a paper from the envelope, if the code number is one, the treatment will be done with a pink needle, and if it is number two, the treatment will be done with a green needle. became. N/A Trigger finger. Intervention 1: Intervention group: A1 poly release by entering the poly at an angle of 45 degrees from the surface of the hand with a pink needle and then opening the skin of the hand and observing the amount of release and damage. Intervention 2: Control group: A1 poly release by entering the poly at an angle of 45 degrees from the surface of the hand with a green needle and then opening the skin of the hand and observing the amount of release and damage. Yes - There is a plan to make this available What will be shared: The written informed consent form will be provided to the participants before the procedure, and then it will be included in the thesis. We have also published it in the researcher system. The data of the study also includes the results of the variables, including the amount of Poly release, the amount of vascular, tendon and tissue damage that is included in the thesis report When: The consent form will be placed in the attachments section after the thesis is printed. Also, the data of the participants is included in the thesis To whom: All people who have access to the full text of the thesis Conditions: It can be modeled in similar studies Where to obtain: Email to the general supervisor of the thesis Dr. Afsaneh Bagheri dr.afsanehbagheri@gmail.com How to obtain: After sending the email to the general supervisor, the thesis can be received within 1 week Comments:
