Efficacy of Ultrasound-Guided Needle Knife Release for Trigger Finger

Efficacy of Ultrasound-Guided Tri-Directional Needle Knife Release for Trigger Finger

Efficacy of ultrasound-guided tri-directional needle knife release in treating patients with trigger finger. The study evaluates safety, effectiveness, and recovery outcomes of a minimally invasive procedure compared to conventional approaches.

This is a clinical trial designed to investigate the efficacy and safety of ultrasound-guided tri-directional needle knife release in patients with trigger finger, especially those patients for whom conservative treatments have failed. Trigger finger is caused by of thickening of the A1 pulley, leading to pain and stiffness, which results in limitation of the hand. The procedure will be carried out under local anesthesia and guided by ultrasound to be very accurate and safe, avoiding all possible risks. Patients will be assessed for better improvement in hand functioning, pain scale basing on visual analog scale, and above all patient overall satisfaction.

Inclusion Criteria:

• Idiopathic TF at the level of A1 pulley
• Trigger finger of Green's grades II or III or IV (moderate to severe)
• Symptoms persist for at least three months despite conservative treatments.
• Ability to provide informed consent and comply with follow-up requirements.

Exclusion Criteria:

• Patients with secondary causes of TF like diabetes mellitus, rheumatoid arthritis, gout, hypothyroidism, amyloidosis, and sarcoidosis.
• Patients with TF of Green's grade I.
• Previous surgical intervention on the affected digit.
• Allergy or contraindication to local anesthetics.
• Pregnancy or lactation.
• Inability to comply with follow-up assessments.
