“…Division of the canal may be carried out in connection with carpal tunnel release, although expansion of the Guyon´s canal may occur in connection with a carpal tunnel release with improvement in two-point discrimination of also ulnar nerve innervated fingers [ 167 ]. The postoperative handling is the same for both surgical procedures [ 168 , 169 ].…”

Peripheral nerves consist of delicate structures, including a rich microvascular system, that protect and nourish axons and associated Schwann cells. Nerves are sensitive to internal and external trauma, such as compression and stretching. Ulnar nerve entrapment, the second most prevalent nerve entrapment disorder after carpal tunnel syndrome, appears frequently at the elbow. Although often idiopathic, known risk factors, including obesity, smoking, diabetes, and vibration exposure, occur. It exists in all adult ages (mean age 40–50 years), but seldom affects individuals in their adolescence or younger. The patient population is heterogeneous with great co-morbidity, including other nerve entrapment disorders. Typical early symptoms are paresthesia and numbness in the ulnar fingers, followed by decreased sensory function and muscle weakness. Pre- and postoperative neuropathic pain is relatively common, independent of other symptom severity, with a risk for serious consequences. A multimodal treatment strategy is necessary. Mild to moderate symptoms are usually treated conservatively, while surgery is an option when conservative treatment fails or in severe cases. The decision to perform surgery might be difficult, and the outcome is unpredictable with the risk of complications. There is no consensus on the choice of surgical method, but simple decompression is relatively effective with a lower complication rate than transposition.

“…Symptoms, such as tingling, numbness or loss of grip strength can occur among cyclists for days, up to months [10]. A retrospective study by Lee et al between January 2001 -December 2020 reviewed patients who underwent surgical management of GCS [12]. The authors listed 20 professions of the patients who suffered from this condition, and the most common occupations were office worker (19,6%), housewife (10,7%) and manual worker (8,9%).…”

Introduction and Objective. Guyon canal syndrome (GCS) is rare neuropathy of the ulnar nerve, caused by its compression at the level of the wrist. In GCS, nerve compression may be caused by endogenic and exogenous reasons. It leads to motor or sensory disfunction regarding IV and V finger and hypothenar area. When symptoms ocurr among cyclists, the conditio is described as handlebar palsy -malfunction due to long-distance bike rides, as a result of repeatable vibrations and bearing bodyweight on wrists and hands. Review methods. The Sumary is based on academic literature and scientific publications available in Portal Komunikacji Naukowej, PubMed and NCBI -National Library of Medicine databases. After evaluation of abstracts, articles were selected and analyzed, considering the references citated. Publications that were analyzed, was two academic literature positions in Polish and both Polish and international publications from the fields of neurology, orthopaedics and radiology, containing a prospective study, retrospective study, systematic review, case study and several articles. Brief description of the state of knowledge. Diagnostic methods of GCS were based on the evaluation of clinical symptoms and radiological or electrophysiological methods, such as USG, MRI or EMG. Treatment is based mainly on conservative management -rest, NSAIDs and steroid injections. Cyclists should take into consideration change of gear or bike position. The ultimate methods are surgical treatments, based on relieving compression of the ulnar nerve. Summary. Guyon canal syndrome is a significantly rare condition, often connected with sport activities, leading to malfunction of the hand mainly in its hypothenar area, which can be treated conservatively and surgically.

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.
