Anatomical variations of the ulnar nerve have been described at the level of the elbow and in Guyon's canal, while the path in the forearm has always been assumed to be constant. We present a case of compressive ulnar neuropathy at the wrist pre-disposed by a presumed congential variation of the path of the ulnar nerve at the level of the wrist which improved following surgical release of the constriction caused as a result of it.

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.

AbstractWe treated an extremely rare case of osteoid osteoma of the pisiform. Pisiform hypertrophy caused persistent pain and ulnar nerve irritation at Guyon's canal after the initial trauma. The re-enlargement of the pisiform attracted our attention allowing us to ultimately diagnose the condition as osteoid osteoma and treat the patient with a successful clinical result.

The study objectiveis to analyze the existing research literature devoted to this problem and to assess clinical characteristics and specific features of the diagnosis and rational neurosurgical treatment for ganglion cyst of Guyon’s canal (GCGC) that caused compression neuropathy of the ulnar nerve.Materials and methods.Since 1955, researchers reported only 19 cases of ganglion cysts located in the wrist area and associated with tunnel neuropathy of the ulnar nerve. Since this condition is extremely rare, we present our own clinical observations.Results.Using the literature data, we described various types of ulnar nerve compression according to individual nerve characteristics determining clinical manifestations of GCGC. We analyzed the prevalence of GCGC among patients of various age and gender, disease pathogenesis, and main diagnostic methods. A patient with GCGC-associated compression ischemic neuropathy of the ulnar nerve was treated in the neurological clinic of the I. M. Sechenov First Moscow State Medical University in 2016. Using visualization tools, we found a ganglion cyst located on the palmar surface at the level of the hook-shaped bone. The cyst caused medial displacement of the ulnar nerve and ulnar artery. We performed microsurgical decompression of the right ulnar nerve at the level of Guyon’s canal and removed the articular ganglion cyst using a standard procedure. In the postoperative period, we observed partial regression of neurological disorders.Conclusion.To identify the cause of ulnar nerve neuropathy in Guyon’s canal, a physician should consider both clinical and electrophysiological data and the results of ultrasound examination and/or magnetic resonance imaging. A detailed examination of these patients allows clarifying morphological characteristics of the lesion and identifying such a rare lesion as ganglion cyst.
