Carpal tunnel syndrome is a common condition frequently requiring surgical intervention. We describe a new minimally invasive surgical technique for carpal tunnel release utilizing ultrasound (US) visualization.
The technique was performed on 20 fresh frozen cadaver specimens. A surgical metallic probe with a "U"-shaped trough and upward curved distal tip was precisely positioned in the carpal tunnel with US guidance followed by division of the flexor retinaculum (FR) with a "V"-shaped scalpel.
Complete division of the FR was confirmed by US. Dissection performed on the specimens confirmed complete release of FR and absence of neurovascular injury. The distance from the division of the FR to these structures, the "safety margins," was measured.
This new technique for carpal tunnel release appears to combine the safety and efficacy of open carpal tunnel surgery with the advantages of the minimally invasive techniques.
腕管综合征是一种常见病症，常需手术干预。我们描述一种利用超声（US）可视化技术进行腕管松解的新型微创手术技术。
该技术在20个新鲜冷冻尸体标本上实施。将带有“U”形槽和向上弯曲远端尖端的手术金属探针在超声引导下精确置于腕管内，随后用“V”形手术刀切开屈肌支持带（FR）。
超声证实FR完全切开。对标本进行的解剖证实FR完全松解且无神经血管损伤。测量了从FR切开处到这些结构的距离，即“安全边缘”。
这种新型腕管松解技术似乎结合了开放性腕管手术的安全性和有效性以及微创手术技术的优势。
