Official Title: Comparison of Long-term Effect in Different Sessions of Perineural Injection With Dextrose for Carpal Tunnel Syndrome
Brief Summary: Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy with involving compression of the median nerve in the carpal tunnel.
The technique of perineural injection therapy (PIT) by using 5% dextrose (D5W) is now commonly used for peeling the nerve from surrounding soft tissue (called nerve hydrodissection), which may help antineurogenic inflammation, allow the impulse to pass, and rescue the nerve with ischemic damage.
However, the evidence and reference of PIT and nerve hydrodissection are very seldom until our series researches since 2017.
Moreover, our research revealed PIT with D5W is more beneficial than that of corticosteroid in patients with mild-to-moderate CTS at 4 to 6 months postinjection.
However, the accumulative effect and long-term effect (more than 6 months) of PIT is still unknown.
Hence, we design a randomized, double- blind, controlled trail to assess the long-term effect of ultrasound-guided PIT in patients with CTS.
The aim one is to survey the possible accumulative effect of different sessions of PIT (6 months follow-up) and aim two is to evaluate the long-term effect and safety of PIT (one year follow-up).
