Summary

A new ultrasound-guided hydrodissection technique simplifies carpal tunnel syndrome treatment by targeting two key areas with a single needle entry. This method shows promise for effective median nerve hydrodissection.

Area of Science:

  • Musculoskeletal Ultrasound
  • Interventional Pain Management
  • Anatomy

Background:

  • Ultrasound-guided hydrodissection (HD) is a minimally invasive treatment for carpal tunnel syndrome (CTS).
  • Current HD techniques can be complex, requiring multiple needle entries or repositioning for adequate perineural spread around the median nerve.
  • A simplified, standardized approach is needed to improve procedural efficiency and safety.

Purpose of the Study:

  • To describe a novel ultrasound-guided single-entry dual-target HD technique for CTS.
  • To evaluate the anatomical feasibility of this technique in cadavers.

Main Methods:

  • A standardized scanning approach initiated at the first carpometacarpal (1st CMC) joint and translated medially was used.
  • A single-entry, distal-to-proximal in-plane needle trajectory targeted the undersurface of the transverse carpal ligament (TCL) and the perineural plane.

  • 10 mL of methylene blue was injected per wrist in a fresh-frozen cadaver, followed by dissection.

    • Main Results:

    • Cadaveric dissection confirmed dye surrounded the median nerve superficially and deeply, indicating circumferential perineural halo formation.
    • The technique demonstrated proximal longitudinal spread from the single entry site.
    • The anatomical feasibility of the hydrodissection plane was supported.

    Conclusions:

    • The described single-entry dual-target HD technique offers a potentially practical framework for CTS treatment.
    • This approach may enhance procedural efficiency compared to existing methods.
    • Further clinical studies are necessary to validate efficacy and safety.
