“…The findings based on the individual case reports may not represent the true distribution of causes. One retrospective study of 31 subjects by Murata et al found the most common cause to be idiopathic (45%) [12]. Other important causes to consider include ulnar artery disease, acute trauma or fracture, aberrant muscles, tumors, osteoarthritis, rheumatoid arthritis, joint dislocations, and activities with prolonged wrist extension [4,5,12].…”

Ulnar Neuropathy at the Wrist

A case of ulnar nerve compression at the wrist within Guyon's canal is reported. The clinical presentation initially appeared consistent with an ulnar nerve entrapment at the elbow. The true diagnosis of an ulnar sensorimotor nerve lesion occurring within the canal of Guyon was made electrophysiologically. Magnetic resonance imaging demonstrated compression of the nerve within the canal by a ganglionic cyst, which was confirmed by surgical intervention. Ulnar nerve entrapment at the wrist is uncommon and difficult to diagnose; therefore, it is important to understand the nerve's anatomical course and distribution to allow for accurate diagnosis by clinical and electrodiagnostic evaluations. Electrodiagnosis is an important tool in identifying ulnar nerve lesions at the wrist while excluding other disorders in the differential and recognizing coexisting pathology.

“…It consists in disappearance of paresthesias in the ulnar nerve territory after CTS surgical release [5,7]. In addition, Murata et al [36] noted that in case of associated idiopathic CTS and Guyon's canal syndrome, the only median nerve neurolysis can improve the symptoms in ulnar nerve territory. Thus, the first studies to investigate this hypothesis used clinical tests.…”

“…4 Ulnar nerve compression syndrome at the wrist is rarer than carpal tunnel or ulnar compression at the elbow. 5,6 Idiopathic and traumatic causes would be most common 7 ; cysts and ganglia would be primary alternatives, 8,9 following anomalous muscles or tendons, 10,11 periarthritis, 12 and tumors as lipomas [13][14][15] and giant cell tumor. 16 Occupational or traumatic hyperactivity can cause neurovascular syndromes in the Guyon channel.…”

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 fi nger and wrist pain with fl exion, 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 fl ow, duplex-Doppler ultrasonography (US) of the subclavian to digital vessels was performed using 3-to 13-MHz transducers. Interpretation focused on fl ow 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 fl ow with opened hand. Hand closure interrupted diastolic fl ow except in the ulnar circulation to the fourth digit. Common digital arteries feeding digits 3-4 and 4-5 had signifi cantly more diastolic fl ow than the artery feeding digits 2-3. Diastolic fl ow through a dilated ulnar artery despite hand closure was associated to a millimetric arteriovenous fi stula in the fourth fi nger. 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 fl ow and hyperthermia associated with a fourth digit fi stula 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.
