Occupational ulnar neuropathy at the elbow joint develops in the course of long term direct pressure on the nerve and a persistently flexed elbow posture, but first of all, it is strongly associated with "holding a tool in a certain position" repetitively. Therefore, computer work only in exceptional cases can be considered as a risk factor for the neuropathy. Ulnar hypermobility at the elbow m...

Significant excursion of the ulnar nerve is required for unimpeded upper extremity motion. This study evaluated the excursion necessary to accommodate common motions of daily living and associated strain on the ulnar nerve. The 2 most common sites of nerve entrapment, the cubital tunnel and the entrance of Guyon's canal, were studied. Five fresh-frozen, thawed transthoracic cadaver specimens (1...

OBJECTIVE The present study's aim was to analyze the late responses' parameters in order to determine the utility of each one. METHODS The study, conducted on a total of 325 patients with entrapment neuropathy of the median nerve and 36 with entrapment neuropathy of the ulnar nerve, included the bilateral evaluation of the median and the ulnar nerve and analysis of 20 F-wave and 4 A-wave para...

Objective-To investigate whether "diseased nerves" are more prone to entrapment neuropathy than normal nerves. Nerve conduction studies of human neuropathies have shown that electrophysiological abnormalities are often most prominent at potential sites of nerve entrapment, and entrapments are more common in patients with radiculopathies-a concept designated as "double crush". As entrapment neur...

Ulnar nerve palsy is a rare complication of closed midshaft forearm fractures; only 8 cases have been reported. This article describes a case of ulnar nerve palsy associated with a midshaft forearm fracture. A 12-year-old girl sustained a right midshaft forearm fracture. Whether she had a peripheral nerve injury was unknown due to strong pain. She underwent emergency manual reduction and intram...

Aim. To evaluate the diagnostic value of ultrasonography and magnetic resonance imaging (MRI) in patients with ulnar neuropathy at the elbow (UNE). Methods. We prospectively performed electrodiagnostic, ultrasonographic, and MRI studies in UNE patients and healthy controls. Three cross-sectional area (CSA) measurements of the ulnar nerve at multiple levels along the arm and maximum CSA(-max) we...

Objectives: A prospective case control study was conducted to calculate normal dimensions of ulnar nerve and study the size, echotexture and morphologic alterations in ulnar nerve in patients with leprosy. Methods: The study group included 48 patients diagnosed with leprosy on basis of clinical, bacteriologic and/or histopathologic evaluation. Sonographic measurements were taken at 3 levels aro...

Background In the treatment of cubital tunnel syndrome (CuTS), in situ ulnar nerve decompression is commonly used. This study aims to investigate predictive factors for poor recovery and ulnar nerve instability following this procedure. Methods We enrolled 235 patients who underwent in situ ulnar nerve decompression for the treatment of CuTS from January 2010 to December 2014. All patients un...

Ulnar nerve palsy subsequent to a fracture of the distal radius is extremely rare compared to a median nerve injury. The lesion tends to occur in younger patents with a high-energy mechanism of injury and a severe injury pattern consisting of wide displacement, comminution, combined distal ulnar fracture and open fracture. The mechanism of injury can contribute to a direct contusion and tractio...
