Ultrasound guidance allows a carpal tunnel release to be performed with smaller incisions and quicker recovery than traditional open or endoscopic surgery. A study was conducted to evaluate the long-term effectiveness of ultrasound-guided carpal tunnel release in improving function and discomfort in patients with carpal tunnel syndrome.

A retrospective review was conducted of 61 ultrasound-guided carpal tunnel release procedures performed in 46 patients (15 bilateral procedures) with clinically diagnosed carpal tunnel syndrome. These were performed under local anesthetic at an outpatient radiology office using the SX-One MicroKnife® (Sonex Health). Patients answered three questionnaires assessing the affected wrist's function and discomfort immediately pre-procedure, 2 weeks post-procedure, and at least one-year post-procedure. Higher scores indicated increasing disability. Patients also answered a global satisfaction question at follow-up. Pre- and post-procedure scores were compared using paired Wilcoxon signed-rank tests.

The 46 patients included 25 women and 21 men. The mean age was 60.6 years (range 21-80). Follow-up questionnaires were obtained for 90% (55/61) of wrists, a median of 1.7 years post-procedure, with further declines in median scores: 2.3. At long-term follow-up, 96% (52/54) of wrists demonstrated lower QDASH, and 98% (53/54) lower BCTSQ, vs. pre-procedure scores. 93% (37/40) of surveyed patients were satisfied/very satisfied with long-term outcomes. No immediate postoperative complications occurred. Two patients required surgical intervention 8-10 days postoperatively, one for infection following injury and one for post-traumatic compartment syndrome. Ultrasound-guided carpal tunnel release quickly improves hand function and reduces hand discomfort; improvement persisted beyond one year.
