Pathologies affecting this canal include traumatic injuries, compressive neuropathies like ulnar tunnel syndrome, and space-occupying lesions such as ganglion cysts. Ulnar tunnel syndrome, characterised by numbness, tingling, and weakness in the ulnar nerve distribution, is a prevalent condition that can severely impair hand function. The canal\u2019s intricate anatomy is defined by surrounding ligaments and bones, divided into three zones, each containing distinct neural structures. Variations, including aberrant muscles and vascular anomalies, can complicate diagnosis and treatment. Imaging techniques are essential for evaluating these conditions; ultrasound provides real-time, dynamic assessments, while magnetic resonance imaging (MRI) offers detailed visualisation of soft tissues and bony structures, aiding in pre-surgical documentation and pathology evaluation. This review article explores the anatomy, pathologies, and imaging modalities associated with Guyon\u2019s canal and underscores the necessity of understanding Guyon\u2019s canal\u2019s anatomy and associated pathologies to improve diagnostic accuracy and management strategies. By integrating anatomical insights with advanced imaging techniques, clinicians can enhance patient outcomes and preserve hand function, emphasising the need for increased awareness and research in this often-neglected area of hand anatomy.<\/jats:p>","DOI":"10.3390\/diagnostics15050592","type":"journal-article","created":{"date-parts":[[2025,2,28]],"date-time":"2025-02-28T10:12:33Z","timestamp":1740737553000},"page":"592","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Unveiling Guyon\u2019s Canal: Insights into Clinical Anatomy, Pathology, and Imaging"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4912-1415","authenticated-orcid":false,"given":"Sonal","family":"Saran","sequence":"first","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, AIIMS Rishikesh, Rishikesh 249203, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saavi","family":"Pellakuru","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal Radiology, Royal Orthopaedic Hospital, Birmingham B31 2AP, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6301-1776","authenticated-orcid":false,"given":"Kapil","family":"Shirodkar","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal Radiology, Royal Orthopaedic Hospital, Birmingham B31 2AP, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ankit","family":"Shah","sequence":"additional","affiliation":[{"name":"Eclat Imaging Centre Mumbai, Mumbai 400056, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aakanksha","family":"Agarwal","sequence":"additional","affiliation":[{"name":"Department of Radio-Diagnosis, Mahatma Gandhi University of Science and Technology, Jaipur 302001, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ankur","family":"Shah","sequence":"additional","affiliation":[{"name":"Sadbhav Imaging Centre, Ahmedabad 380006, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4379-1266","authenticated-orcid":false,"given":"Karthikeyan","family":"Iyengar","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Southport and Ormskrik Hospital, Mersey and West Lancashire Teaching NHS Trust, Southport PR8 6PN, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7998-2980","authenticated-orcid":false,"given":"Rajesh","family":"Botchu","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal Radiology, Royal Orthopaedic Hospital, Birmingham B31 2AP, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,28]]},"reference":[{"key":"ref_1","first-page":"92","article-title":"Note on a special canal in the anterior annular ligament of the carpus for the passage of the ulnar artery","volume":"12","author":"Guyon","year":"1861","journal-title":"Comptes Rendus Soc.
