Trigger finger, also known as stenosing tenovaginitis, is a common inflammatory disorder that affects the A1 pulleys of the fingers, causing hand discomfort and pain. Surgical treatment aims to release the A1 pulley, reducing friction and alleviating pain. While open A1 pulley release has been the gold standard, there is a growing trend toward minimally invasive percutaneous approaches. These techniques, including ultrasound-guided percutaneous release, offer simplicity, reduced pain and recovery time, absence of a scar, and lower costs. They have shown high success rates and minimal complications, although concerns remain about incomplete releases and tendon injuries with needle techniques. The shift toward minimally invasive techniques represents a significant advancement in trigger finger treatment, providing effective symptom relief, cost reduction, shorter recovery periods, and improved patient outcomes. Diagnosis is primarily clinical, with patients experiencing clicking, snapping, stiffness, and loss of finger mobility. Ultrasonography can support diagnosis and visualize the tendon-pulley interface. Surgical options, including percutaneous release, are considered when conservative interventions fail. The personal technique described in this chapter involves ultrasound-guided percutaneous release using a specialized surgical knife. The technique is indicated for the release of long digits and offers a safe and effective method with minimal complications. Postoperative care involves minimal bandaging and immediate use of the hand for daily activities. The technique has shown excellent outcomes, with no persistent or recurrent triggering, infections, tendon injuries, or neurovascular damage observed.
