Objectives/Interrogation: We used new ultrasound-guided instrument for percutaneous release with 18-gauge needle for trigger finger. This instrument was developed to avoid the complications of incomplete release and flexor tendon, digital nerve, and digital artery damage under ultrasound-guided. (Double guide-type tendon sheath incision instrument, Nara Seiko INC®, Japan).

We compared open surgical release (Group A) with ultrasound-guided percutaneous release with this instrument (Group B) for trigger finger.

Methods: 18 fingers were treated with open surgery (Group A) and 16 fingers were treated with ultrasound-guided percutaneous release with this instrument (Group B). Functional and clinical outcomes of the both groups were evaluated at 1.5, 3, and 6 month postoperatively and were compared between the patients with the Group A and B.

Group A patients allowed wetting hands after the stitches have been removed. Group B patients allowed soaking hands the second postoperative day.

Results and Conclusions: The groups were similar at base line in terms of sex, age. There are no postoperative complication and secondary operation procedures. At 1.5 months postoperatively, the average VAS score was 32 mm in the Group A, and 15mm in the Group B, respectively. There was a significant difference between the two groups (p<0.05). The average extension of PIP joint at 3 months postoperatively was -10 degree in the group A, and -3 degree in the group B, respectively. There was a significant difference between the two groups (p<0.05). At 6 months postoperatively, there was no significant difference between the two groups regarding the pain level on a visual analogue scale, the Quick DASH, range of motion of PIP.Our data indicate that both procedures are highly effective for treatment of trigger finger without postoperative complication. While, release with new ultrasound-guided instrument yielded better results compared to the open technique in the early postoperative period, in respect of improvement of VAS and extension of PIP joint. Besides, after 6 months, this study shows the functional outcomes are comparable between two groups.

The ultrasound-guided percutaneous release with this instrument may make sure to complete release and provide earlier recovery of the finger function in the early postoperative period.
