Nerve Hydrodissection for Carpal Tunnel
A study published in Radiology suggests that ultrasound-guided nerve hydrodissection is an effective, steroid-free alternative for treating carpal tunnel syndrome. The randomized trial compared this technique against traditional corticosteroid injections to evaluate long-term relief and side effects.
Why it matters
This offers a potentially safer, non-pharmacological treatment option for a common condition affecting millions, reducing the risks associated with long-term steroid use.
A minimally invasive ultrasound-guided technique offers long-term relief for patients with carpal tunnel syndrome with fewer side effects than steroids, according to a new study published in Radiology .
Carpal tunnel syndrome is associated with repetitive motions of the wrist and hands that lead to numbness, tingling, weakness and pain. Research has shown that the condition affects roughly 5% to 10% of the general population over their lifetimes, and incidence is rising.
Corticosteroids injection, a common treatment to reduce swelling and relieve pressure on the nerve, has limitations.
"Traditional steroid injection for carpal tunnel syndrome often provides only temporary relief, thus requiring repeats of the procedure," said study co-author Anupama Tandon, MD, professor in the Department of Radiodiagnosis and Imaging at University College of Medical Sciences and Guru Teg Bahadur Hospital in Delhi, India. "Further, steroids carry risk of localized skin changes, fat thinning and tendon weakening."
