PMID 39560285WHAT IT FOUND
In 40 fingers from 30 patients, a procedure using lidocaine, hydrodissection, ultrasound-guided modified needle release, and steroid injection had no recurrence at 6 to 32 months and one complication.
This small case series cannot separate the components.
Key findings
01No recurrent triggering was reported at the last follow-up, which averaged 11 months and ranged from 6 to 32 months.
02One complication was recorded among 28 cases: tenosynovitis, which resolved with a subsequent corticosteroid injection; no neurovascular damage or subjective bowstringing was reported.
03Patients returned to their baseline pain an average of 2.75 days after the procedure.

What it does not show
The analysis included 40 digits from 30 patients, so rare complications and true recurrence rates could be missed. The study was retrospective, single physician, and had no control group or randomization, so it cannot compare this technique with open surgery or other percutaneous methods. Procedure time was recorded for only the last 10 cases, and the paper did not examine cost. The outcome counts were not fully explained: 40 digits were analysed, but the complication result was reported among 28 cases. The release was performed with lidocaine, hydrodissection, and a triamcinolone injection, so the effect of any single component cannot be separated. No outcomes were compared by race, gender, ethnicity, vocation, symptom duration, or thumb versus other finger.
Declared interests
No conflicts of interest were declared, and no funding source was reported.
The easy way to misread this
Do not read the absence of recurrence as proof that the modified needle release alone worked. The procedure also included lidocaine anesthesia, hydrodissection, and a triamcinolone injection, and the study was a small retrospective case series with no control group.
