Ultrasound-guided saline injection offers lasting relief for carpal tunnel patients
Researchers at the Radiological Society of North America report that a 15-minute ultrasound-guided hydrodissection procedure helped 63 patients avoid surgery in October 2026.
Study findings on pain relief
A clinical trial involving 63 patients found that fluid injection around a compressed nerve provided longer-lasting improvements than traditional steroid injections. The procedure uses ordinary saline to free the median nerve in the wrist without introducing steroids. Participants experienced reduced pain, numbness, and weakness in their hands after this minimally invasive technique.
Potential to delay operations
The results published in Radiology suggest this method serves as a promising alternative for those whose symptoms did not improve with conventional treatments. Researchers indicate the technique could help some individuals delay or completely avoid the need for carpal tunnel surgery.
