Ulnar nerve neuropathy at the elbow represents the second most frequent compression neuropathy of the upper extremity. Of the five different anatomical areas responsible for ulnar nerve compression at the elbow region, the epitrochlear-olecranon channel and Osborne’s arcade are the most common. An additional cause of nerve damage is a dynamic process in which the ulnar nerve dislocates anterior...

The ulnar nerve arises from the medial brachial plexus and innervates the muscles of the forearm and parts of the hand. It also carries sensory neurones supplying the skin of the back of the forearm, the palm and the ring and little fingers. Most damage to the ulnar nerve occurs at the elbow where it passes behind the medial epicondyle and under Osborne's ligament (humeroulnar aponeurotic arcad...

abstract a patient with a 3-month history of headache refractory to pain medication was admitted. the ct scan and mri showed evidence of a posterior fossa mass. this was pathologically confirmed as an extra medullary plasmacytoma (emp). he had a pathologic fracture of the left humerus 7 years ago while the radiologist was unaware at the time of diagnosis. a solitary bone plasmacytoma (sbp) was ...

Double compression of the ulnar nerve, including Guyon's canal syndrome associated with cubital tunnel syndrome caused by the anconeus epitrochlearis muscle, is a very rare condition. We present a case of double crush syndrome of the ulnar nerve at the wrist and elbow in a 55-year-old man, as well as a brief review of the literature. Although electrodiagnostic findings were consistent with an u...
