Abstract

Objective: Guyon's canal syndrome is caused by compression of the ulnar nerve at the wrist, occasionally requiring decompression surgery. In recent times, minimally invasive approaches have gained popularity. The aim of this study was to assess the efficacy and safety of ultrasound-guided thread release for transecting the palmar ligament in Guyon's canal without harming surrounding structures, in a cadaveric specimen model.

Methods: After ethical approval, thirteen ultrasound-guided thread releases of Guyon's canal were performed on the wrists of softly embalmed anatomic specimens. Cadavers showing injuries or prior operations at the hand were excluded. Subsequently, the specimens were dissected, and the outcome of the interventions and potential damage to adjacent anatomical structures as well as ultrasound visibility were evaluated with a score from one to three.

Results: Out of 13 interventions, a complete transection was achieved in ten cases (76.9%), and a partial transection was documented in three cases (23.1%). Irrelevant lesions on the flexor tendons were observed in two cases (15.4%), and an arterial branch was damaged in one (7.7%). Ultrasound visibility varied among specimens, but essential structures were delineated in all cases.

Conclusion: Ultrasound-guided thread release of Guyon's canal has shown promising first results in anatomic specimens. However, further studies are required to ensure the safety of the procedure.

Relevance statement: Our study showed that minimally invasive ultrasound-guided thread release of Guyon's canal is a feasible approach in the anatomical model. The results may provide a basis for further research and refinement of this technique.

Key points: • In Guyon's canal syndrome, the ulnar nerve is compressed at the wrist, often requiring surgical release. • We adapted and tested a minimally invasive ultrasound-guided thread release technique in anatomic specimens. • The technique was effective; however, in one specimen, a small anatomic branch was damaged.

超声引导下盖雍氏管微创螺纹松解术:尸体标本的初步经验。
目的:古永氏管综合征是由手腕处尺神经受压引起的,偶尔需要进行减压手术。近来,微创方法越来越受欢迎。本研究的目的是在尸体标本模型中,评估超声引导下线松解术横切古永氏管掌侧韧带的有效性和安全性,同时不损害周围结构:方法:经伦理批准后,在软防腐解剖标本的手腕上进行了 13 次超声引导下的圭雍氏管螺纹松解术。不包括手部有伤或曾做过手术的尸体。随后,对标本进行解剖,并对介入的结果、对邻近解剖结构的潜在损伤以及超声波可见度进行评估,评分从1分到3分不等:结果:在 13 例介入手术中,10 例(76.9%)实现了完全横断,3 例(23.1%)实现了部分横断。在两个病例(15.4%)中观察到了屈肌腱的相关病变,在一个病例(7.7%)中观察到了动脉分支受损。不同标本的超声能见度不同,但所有病例的重要结构都能清晰显示:结论:超声引导下的盖雍氏管螺纹松解术在解剖标本中显示出良好的初步效果。然而,为确保手术的安全性,还需要进一步的研究:我们的研究表明,微创超声引导下的圭雍氏管螺纹松解术在解剖模型中是一种可行的方法。研究结果可为进一步研究和完善该技术提供依据:- 要点:在圭雍氏管综合征中,尺神经在手腕处受到压迫,通常需要手术松解。- 我们在解剖标本中改良并测试了超声引导下的微创螺纹松解技术。- 该技术效果显著,但在一个标本中,一个小的解剖分支受损。
