RESUMO
Purpose: Trigger finger, a stenosing tenosynovitis of the flexor tendon at the A1 pulley, can cause pain and impair daily activities. Despite common surgical interventions, postsurgical complications are frequent, prompting the search for less invasive techniques. Methods: An experimental study was conducted on fresh cadavers to compare three techniques: the first using a PulleyCut without ultrasound guidance, the second using a PulleyCut with ultrasound guidance, and the third using a percutaneous needle technique. The complete release of the A1 pulley, integrity of the A2 pulley, flexor tendons, and neurovascular bundles were assessed. Results: The new device group and the ultrasound-guided group demonstrated 100% complete release of the A1 pulley, whereas the needle group achieved only 38% success. There were no A2 pulley injuries in any group. Flexor tendons were injured in 7% of cases in the new device group and 77% in the needle group. A neurovascular injury occurred in the needle group. Conclusions: Compared with the percutaneous needle technique, the new device proved safe and effective for A1 pulley release, minimizing damage to flexor tendons and neurovascular structures. Ultrasound did not provide significant advantages, suggesting that the new device can be confidently used without ultrasound assistance. The PulleyCut represents a promising percutaneous technique for trigger finger treatment, demonstrating superiority over the needle technique in terms of efficacy and safety. These results encourage future clinical investigations to validate its practical application. Type of study/level of evidence: Therapeutic IIc.
RESUMO
PURPOSE: Trigger finger (TF) is a common hand condition that can be treated with surgery. We conducted a systematic review and meta-analysis to assess whether ultrasound-guided (US-guided) percutaneous surgery is superior to other conventional surgical methods. METHODS: We conducted a comprehensive search in Medline, Embase, and the Cochrane Library to identify relevant studies. We included randomized clinical trials (RCTs) and observational studies comparing US-guided TF release with blind percutaneous or open approaches. We combined Risk Ratios (RR) and Mean Differences (MD) with 95% Confidence Intervals (CI) across studies. Data processing and analysis were conducted using R software, version 4.3.1. RESULTS: Our analysis included eight RCTs and two observational studies with 555 patients. US-guided surgery significantly reduced postoperative DASH scores (MD -3.75 points; 95% CI = -7.48, -0.02; p < 0.01), shortened time to resume activities (MD -11.52 days; 95% CI = -16.13, -6.91; p < 0.01), hastened discontinuation of oral analgesics (MD -4.44 days; 95% CI = -8.01, -0.87; p < 0.01), and improved patient satisfaction scores (RR 1.13; 95% CI = 1.04, 1.23; p = 0.75). There were no significant differences in VAS scores, time to movement recovery, or surgical success rate. CONCLUSION: Ultrasound-guided percutaneous release is a safe, effective, and superior alternative for treating TF compared to other methods, leading to improved DASH scores, quicker recovery, faster cessation of oral analgesics, and enhanced patient satisfaction.
