Objective:
The aim of this study was to evaluate the outcomes of patients treated with a novel minimally invasive complete release of the first dorsal compartment percutaneously under ultrasound guidance using an 18-gauge needle with an 18 blade at the tip.
Design:
This was a retrospective case series. Nine adults (ten wrists) were included in the study of this technique. All patients had failed conservative care and had tenderness to palpation over the first dorsal compartment, a positive Finklestein test, and confirmed tenosynovitis with ultrasound imaging before the procedure. The main outcome measures were reduction in pain as determined by the numeric rating scale and improvement of function determined by the Nirschl Phase scale at both short- and long-term follow-up.
Results:
There was 100% follow-up, with mean (SD) follow-up occurring at 23.1 (9.8) mos (range, 9-42 mos). From preprocedure to follow-up, numeric rating scale pain decreased from 4.1 (SD, 2.5) to 0.0 (SD, 0.0) ( P < 0.001), and Nirschl phase improved from 2.5 (SD, 1.9) to 0.2 (SD, 0.4) ( P = 0.03). No patients required revision open-release surgery or suffered neurovascular complications.
Conclusion:
This technique resulted in significant improvement of pain and function for all patients and no short- or long-term neurovascular complications were seen.
