A 15-Minute Nerve Procedure Challenges Carpal Tunnel Surgery

Surgical release remains the standard answer for chronic median nerve compression when basic splinting fails. That standard now faces clear data from interventional radiology. In a randomized clinical trial involving 63 patients presented at the Radiological Society of North America annual meeting, researchers evaluated ultrasound-guided hydrodissection against standard corticosteroid injections for carpal tunnel syndrome. The technique introduces a saline or dextrose solution directly around the nerve under continuous sonographic visualization, physically separating the median nerve from the inflamed transverse carpal ligament without cutting the tissue.

The trial data demonstrate distinct functional separation over time. While steroid injections provided acute symptom management, benefits peaked early and deteriorated by six months. The hydrodissection cohort sustained reductions in pain scores, measured sensory improvements, and better functional hand capacity through the final follow-up. Using fluid pressure to strip away mechanical adhesions avoids the tissue atrophy and tendon weakening that repeated localized cortisone exposure often causes.

If you manage chronic wrist tingling or grip weakness from repetitive strain, avoid accepting surgery as the only path after splints fail. Request high-resolution dynamic ultrasound imaging from an interventional radiologist or sports physician to evaluate whether fluid-based neurolysis fits your anatomy before you agree to structural incisions.
