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.

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.

Ulnar Tunnel

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.

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.

Canal Syndrome

Objective —Ulnar nerve compression, the Guyon's canal syndrome, is more unusual than carpal tunnel disorders. An exceptional case of a patient with vascular and neurogenic signs and symptoms is described. Patient Presentation —A 26-year-old female physiotherapist presented with neurogenic and arteriovenous signs and symptoms involving the right hand. The patient described fourth finger and wrist pain with flexion, and pain and itching extending to arm and forearm. Sensations worsened when exposed to air conditioning. Enlarged vessels were noted in the medial aspect of the fourth digit; trauma occurred 8 years earlier during attempts to open a nail polish container. Methods —Color flow, duplex-Doppler ultrasonography (US) of the subclavian to digital vessels was performed using 3- to 13-MHz transducers. Interpretation focused on flow waveforms obtained with the hand open and closed, having the left extremity as reference. Thermography was performed with camera Flir 15, room temperature at 21°C (70°F) and relative humidity at 48%. Results —Right subclavian to digital arteries had high diastolic flow with opened hand. Hand closure interrupted diastolic flow except in the ulnar circulation to the fourth digit. Common digital arteries feeding digits 3–4 and 4–5 had significantly more diastolic flow than the artery feeding digits 2–3. Diastolic flow through a dilated ulnar artery despite hand closure was associated to a millimetric arteriovenous fistula in the fourth finger. Hyperthermia saturating at 35°C (95°F) showed channel-like images over the ulnar nerve and artery and fourth digit, compared with 20°C (68°F) for digit 2. Conclusions —US and thermography demonstrated high flow and hyperthermia associated with a fourth digit fistula and abnormal vessels, and ulnar artery dilatation likely associated with ulnar nerve injury. A coadjuvant diagnosis of Guyon's canal syndrome at the wrist was raised.
