متن کاملCompression of the Ulnar Nerve in Guyon's Canal Caused by a Large Hypothenar Cyst
OBJECTIVE We report the case of a 77-year-old man who presented with a long-standing, large swelling of the left hypothenar eminence. This was associated with recent-onset paresthesia and numbness of the ring and little fingers. Magnetic resonance imaging demonstrated a cystic lesion that occupied almost the entire bulk of the hypothenar eminence. METHODS Surgical exploration revealed a 7-cm,...
متن کاملUlnar nerve palsy due to concomitant compression by the anconeus epitrochlearis muscle and a ganglion cyst.
Compression neuropathy of the ulnar nerve at the elbow is commonly caused by constriction at the fibrous cubital tunnel or an anatomical elbow deformity. Many uncommon causes of compression have been described, including Osborne’s band, ulnar nerve subluxation,1 anatomical confines of the cubital tunnel, elbow osteoarthritis, ganglion,2 prominent medial head of triceps,3 and an anconeus epitroc...

Lesions of the ulnar nerve are the most common causes of paralysis of a peripheral nerve.1,2 The cubital tunnel (or sulcus ulnaris) syndrome is the second most frequent compression syndrome of the upper extremities after the carpal tunnel syndrome.3,4 We report our findings in a patient who suffered from cubital tunnel syndrome and underwent subcutaneous anterior transposition, a surgical proce...
متن کاملGanglion Cyst Associated with Triangular Fibrocartilage Complex Tear That Caused Ulnar Nerve Compression
Ganglions are the most frequently seen soft-tissue tumors in the hand. Nerve compression due to ganglion cysts at the wrist is rare. We report 2 ganglion cysts arising from triangular fibrocartilage complex, one of which caused ulnar nerve compression proximal to the Guyon's canal, leading to ulnar neuropathy. Ganglion cysts seem unimportant, and many surgeons refrain from performing a general ...
