Guyon's Canal

Compression of the ulnar nerve in Guyon’s canal is an uncommon phenomenon. Reports of ulnar nerve palsy secondary to ulnar artery pseudoaneurysm at this anatomical location are very rare and equivalent pathology just distal to this site is unheard of. Here we present such a case, which featured a delayed onset of symptoms. This followed penetrating trauma to the hand. Our methods for diagnosis, operative planning and surgical treatment are included.

Guyon's Canal

<p>Ulnar nerve compression at the Guyon’s canal is an uncommon cause of ulnar nerve neuropathy. Among various reasons like trauma, non-union of hook of hamate, anomalous muscle anatomy, thrombosis of the ulnar artery or pseudoaneurysm, ganglion is a common lesion which can compress the ulnar nerve at this site. With proper history taking and physical examination consisting of assessing motor functions and sensation of the hand, a clinician can localize the site of the lesion. Ultrasound is cheap and non-invasive technique which helps to localize the site of lesion and can suggest the nature of the lesion. Surgical decompression of the canal and careful removal of the lesion can help ameliorate the symptoms. In our study the patient presented with sudden onset weakness of the right hand and symptoms progressing within one and half month. With proper muscle charting, sensory examination and with the help of sonography, the main culprit was localized to Guyon’s canal. Excision of the lesion helped in recovery of hand function within 5 months.</p>

Dentre os fatores que podem desencadear a compressão do canal de Guyon inclui-se o aneurisma da artéria ulnar. Uma das abordagens cirúrgicas é a reconstrução microcirúrgica através da ressecção e arteriorrafia término-terminal ou enxerto venoso de interposição. O objetivo deste trabalho é relatar o caso de paciente que desenvolveu neuropatia do nervo ulnar secundária à presença de aneurisma da artéria ulnar no canal de Guyon. Foi realizada a descompressão cirúrgica através de uma abertura do canal e a ressecção do segmento lesionado. A artéria ulnar foi reconstruída através da anastomose término-terminal microcirúrgica. O resultado foi o alívio completo dos sintomas no pós-operatório com manutenção do fluxo vascular. Descritores: Nervo Ulnar; Neuropatia Radial; Ferimentos e Lesões; Aneurisma. Referências Guyon F.

A 43-year-old female is presented who underwent a two-stage tendon reconstruction and developed a low ulnar nerve palsy postoperatively. Exploration found that the tendon graft was passing through Guyon’s canal and that the ulnar nerve was divided. This is a previously unreported complication. The reconstruction is discussed, the literature reviewed and a guide is given on how to identify the correct tissue plane when passing a tendon rod.
