About this study
Official title: Advancing Dupuytren's Contracture Treatment: a Clinical Prospective Study on Ultrasound-Guided Needle Knife Dissection
This study aims to evaluate the efficacy and safety of ultrasound-guided needle knife dissection in treating Dupuytren's contracture. The procedure is designed to improve hund function and minimize complications associated with the conventional surgical methods.
Read the detailed description
Dupuytren's contracture is a disease mainly characterized by the progressive fibrosis of the palmar fascia with subsequent hand deformity and dysfunction. The current study seeks to explore, through this minimally invasive technique, ultrasound-guided needle knife dissection regarding ROM and patient satisfaction. The procedure will be carried out under ultrasound guidance to ensure safety and completeness with the accuracy of precise dissection. Primary outcome measures will concern hand mobility, and secondary measures will evaluate patient self-reported satisfaction and any complications for the 6-month follow-up period.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ultrasound guided needle knife dissectionProcedure or surgery
Also called UGNK procedure
This procedure involves a minimally invasive dissection of the fibrous cords in Dupuytren's Contracture using a needle knife guided by ultrasound imaging. Local anesthesia using 3-5 ml of 1% Lidocaine and 0.25% bupivacaine is administered for patient comfort. The technique aims to improve precision, minimize complications and reduce recurrence.
Device: Sonosite M-Turbo Ultrasound Machine with Linear Probe HFL38x (6-13 MHz) is used for real-time imaging during the procedure.
