Hybrid-J shape needle in ultrasound-guided looped thread carpal tunnel release: a cadaveric study on safety and efficacy.

ABSTRACT:

Background

Carpal tunnel syndrome (CTS) is the most prevalent peripheral nerve entrapment disorder, often requiring surgical intervention. While Ultrasound-guided Looped Thread Carpal Tunnel Release (LTCTR) offers a minimally invasive alternative to carpal tunnel release, its implementation faces limitations due to insufficient specialized instruments. This cadaveric study assesses the Hybrid-J Shape Needle (HJSN), a blunt-tip, J-shaped device designed to improve safety in LTCTR procedures.

Methods

Twenty fresh-frozen cadaveric specimens (40 wrists) were included. Ten junior surgeons were randomly assigned two cadavers, performing LTCTR with normal cannula needle (NCN) on one wrist of the same cadaver, followed by HJSN on the contralateral wrist. Intraoperative structural da
