Background: The percutaneous release is a quick, economical and minimally invasive procedure for treating trigger fingers. It has been performed at Fang Hospital since 2010 using a modified dental plastic filling instrument.
Objective: To determine the outcomes of percutaneous release of trigger finger by using a modified dental plastic filling instrument at Fang Hospital.
Material and Method: A retrospective descriptive study was conducted among 91 patients (91 digits) with trigger fingers Quinnell grade ≥2 who underwent percutaneous release using a modified dental plastic filling instrument at Fang Hospital during January 2010 – December 2019 by single orthopaedic surgeon. Postoperative outcomes collection by telephone included the modified Quinnell grading system, pain score, patient satisfaction and complication information. Data was analyzed using descriptive statistics.
Results: The mean age was 53±9 years (range, 23–84) and 92.3% were female. The most common affected digits were the thumb, middle, ring and index fingers respectively (46.1%, 30.8%, 13.25 and 9.9%). The average duration of symptoms was 7±6 months (range, 1–24). Most of the patients (61.5%) had Quinnell grade 3 of severity and 83.5% had received local steroid injections. The mean follow-up period was 6.5±2.4 years (range, 1–9). Postoperatively, 84.6% of the patients had excellent outcome, 13.2% good and 2.2% poor. The success rate was 97.8%. Seventy-nine patients (86.8%) could do regular hand work without pain and were satisfied. The complications were residual symptoms in Quinnell grade 2 and needed further steroid injections (2 cases) and grade 3 required following open release (2 cases).
Conclusion: The percutaneous release of trigger finger using a modified dental plastic filling instrument had a 97.8% success rate along with low complications. Most patients were satisfied after treatment.
