Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention Group: Ultrasound-Guided Needle Knife Dissection

Participants in this group will undergo ultrasound-guided needle knife dissection for the treatment of Dupuytren's Contracture. Local anesthesia using 3-5ml of 1% lidocaine 0.25% bupivacaine is administered for patient comfort. This procedure is designed to improve hand function with minimal complications.

Group Type EXPERIMENTAL

Ultrasound guided needle knife dissection

Intervention Type 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.
