Introduction: Compression of the ulnar nerve in Guyon’s canal results in ulnar tunnel syndrome (UTS). The patient may present with sensory and motor deficits (zone 1), motor deficit (zone 2), or sensory deficit (zone 3). The most common causes of UTS include ganglion cysts, idiopathic ulnar nerve compression, occupational pressure neuritis (repetitive compression), prolonged compression, hook of hamate fractures, and arterial thrombus or aneurysm. Case Report: We report an atypical cause of UTS involving pigmented villonodular synovitis (PVNS) with a review of the literature. Surgical decompression of the ulnar nerve at Guyon’s canal has resulted in resolving motor weakness and improved interosseous strength at latest follow-up. Conclusion: The most common causes of UTS are ganglion, occupational neuritis, prolonged compression, and ulnar artery thrombi/aneurysms. However, other more rare causes such as PVNS should be considered in the appropriate patient. Keywords: Neuropathy, ulnar nerve, ulnar tunnel.

Canal Syndrome

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.

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>

Canal Syndrome

Guyon's canal syndrome, an ulnar nerve entrapment at the wrist, is a well-recognized entity. The most common causes that involve the ulnar nerve at the wrist are compression from a ganglion, occupational traumatic neuritis, a musculotendinous arch and disease of the ulnar artery. We describe two cases of Guyon's canal syndrome and discuss the anatomy, aetiology, clinical features, anatomical classification, diagnostic criteria and treatment. It is emphasized that the knowledge of both the surgical technique and anatomy is very important for a satisfactory surgical result.

Anomalous Branch

We present a case of isolated Abductor Digiti Minimi (ADM) palsy caused by an anomalous branch from the ulnar artery. Electrophysiology suggested selective involvement of the motor branch to the ADM in the Guyon's canal. Surgical exploration revealed an anomalous branch of the ulnar artery causing a pincer effect on the nerve to the ADM. Division and ligation of this branch effectively decompressed the nerve and the patient recovered satisfactorily. This report highlights the need to consider vascular aberrations as a differential diagnosis for ulnar neuropathy in Guyon's canal.
