1/6. Atypical compression of the deep branch of the ulnar nerve in Guyon's canal by a ganglion. Case report.A 61-year-old woman with an ulnar claw-finger deformity but no sensory loss had a cystic lesion excised from Guyon's canal. The ganglion was in zone 1 of the canal, which is associated with both motor and sensory deficit, but on this occasion it caused motor dysfunction alone.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
2/6. ultrasonography in the diagnosis of ulnar tunnel syndrome caused by an occult ganglion.We report a case of ulnar tunnel syndrome caused by an occult ganglion which was diagnosed preoperatively by ultrasonography.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
3/6. Surgical management of Guyon's canal syndrome, an ulnar nerve entrapment at the wrist: report of two cases.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.- - - - - - - - - - ranking = 0.2keywords = ganglion (Clic here for more details about this article) |
4/6. Ganglion-associated ulnar tunnel syndrome treated by ultrasonographically assisted aspiration and splinting.We describe a case of ulnar nerve compression at the wrist due to a ganglion. This was treated by aspiration of the ganglion under ultrasonography and splinting because the patient was pregnant. The ulnar nerve palsy resolved completely and the ganglion disappeared. A follow-up ultrasonographic examination after 2 years showed no recurrence of the ganglion.- - - - - - - - - - ranking = 0.8keywords = ganglion (Clic here for more details about this article) |
5/6. Compression of the ulnar nerve at the elbow by an intraneural ganglion.A rare cause of ulnar nerve compression at the elbow is presented in this report. A 42 year old right-handed mechanic developed subacute, progressive numbness, tingling and weakness in his right hand. Electrophysiologic studies demonstrated a severe conduction block affecting the ulnar nerve in the retrotrochlear groove but without any sign of major axonal loss. His hand functions were carefully studied prior to surgery. While fine motor tasks were not affected, the hand strength was markedly diminished. At surgery, a 1-cm diameter intraneural ganglion at the site of the conduction block was found and excised. The patient made a dramatic recovery within 6 weeks post-surgery. The conduction block completely resolved and the hand functions also returned to normal. This and other reported cases point to the importance of early diagnosis and intervention.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
6/6. Ulnar neuropathy at Guyon's canal: electrophysiological and surgical findings.Published correlations between electrophysiological and surgical findings are relatively rare in cases of ulnar nerve compression at the wrist, compared to the more common compression of the ulnar nerve at the elbow. We describe a patient who presented with clinical and electrodiagnostic findings of a pure motor ulnar neuropathy involving the territory of the deep branch. Surgical exploration revealed that a ganglion cyst caused compression of the deep ulnar motor branch at Guyon's canal. This case illustrates the usefulness of electrodiagnostic studies in the localization of nerve entrapment prior to surgery.- - - - - - - - - - ranking = 0.2keywords = ganglion (Clic here for more details about this article) |
