OBJECTIVES: To investigate the effects of ultrasound-guided injections of
hyaluronic acid (HA) versus steroid for trigger fingers in adults. DESIGN:
Prospective, double-blinded, randomized controlled study. SETTING: Tertiary care
center. PARTICIPANTS: Subjects with a diagnosis of trigger finger (N=36; 39
affected digits) received treatment and were evaluated. INTERVENTIONS: Subjects
were randomly assigned to HA and steroid injection groups. Both study medications
were injected separately via ultrasound guidance with 1 injection. MAIN OUTCOME
MEASURES: The classification of trigger grading, pain, functional disability, and
patient satisfaction were evaluated before the injection and 3 weeks and 3 months
after the injection. RESULTS:
At 3 months, 12 patients (66.7%) in the HA group
and 17 patients (89.5%) in the steroid group exhibited no triggering of the
affected fingers (P=.124). The treatment results at 3 weeks and 3 months showed
similar changes in the Quinnell scale (P=.057 and .931, respectively). A
statistically significant interaction effect between group and time was found for
visual analog scale (VAS) and Michigan Hand Outcome Questionnaire (MHQ)
evaluation (P<.05). The steroid group had a lower VAS at 3 months after injection
(steroid 0.5+/-1.1 vs HA 2.7+/-2.4; P<.001). The HA group demonstrated continuing
significant improvement in MHQ at 3 months (change from 3wk: steroid -2.6+/-14.1
vs HA 19.1+/-37.0; P=.023; d=.78). CONCLUSIONS: Ultrasound-guided injection of HA
demonstrated promising results for the treatment of trigger fingers. The optimal
frequency, dosage, and molecular weight of HA injections for trigger fingers
deserve further investigation for future clinical applications.
