Background: The median nerve is one of the most important branches of the brachial plexus. Due to the role of the median nerve in sensory and motor innervation of the forearm and hand in the upper limbs, its blood supply is very important. Awareness of variations in the blood supply pattern to this nerve reduces the incidence of necrosis and ischemia of the nerve during surgical and diagnostic ...

introduction: nerve repair is performed in different ways, but which way leads to better results is not known for ceratin. one way is epiperineurial procedure. in this method the fasicules of the nerve are sawn together by thin thread separately. this study aimed to investigate the results of epiperineurial method. materials and methods: in this study 21 subjects who were admitted in taleghani ...

many experimental studies have reported behavioral improvement after transplantation of peripheral nerve tissue into the contused spinal cord, even in large animals. the safety of this treatment in human remains unknown. in this translational phase 1 study, safety of peripheral nerve grafting for chronic spinal cord injuries and possible outcomes are being reported. twelve complete motor spinal...

Median nerves to the hands of 8-15-d-old marmoset monkeys were transected and precluded from regeneration by ligation. Following periods of 0.4-1.5 years, features of organization in the cortical area 3b hand map were assessed neurophysiologically, and compared to features in normally reared monkeys. Cortical features in monkeys with both histories were similar in certain respects. (1) Receptiv...

lipofibromatous hamartoma (lfh) is an extremely rare benign tumor, which is characterized by an excessive infiltration of the epineurium and perineurium by fibroadipose tissues. a 27-year-old woman was diagnosed with left carpal tunnel syndrome (cts) due to (lfh) of the median nerve. lfh was diagnosed by mri and sonography; the characteristic ultrasonographic feature of lfh showed a good correl...

background: compressive neuropathy of median nerve is relatively common but development of an hourglass like constriction is a rare phenomenon. the purpose of this study is to show morphologic changes of median nerve in advances carpal tunnel syndrome. methods: eighty patients with thenar atrophy, anesthesia and paresthesia of first, second and third finger and severe changes of emg‑ncv were ch...

A young patient with symptoms of median nerve compression in carpal tunnel without known risk factors is presented. Ultrasonography and magnetic resonance imaging confirmed an anatomical variation of the median nerve in carpal tunnel, described in the literature as bifid median nerve. The knowledge of the existence ofbifid median nerve is important in planning surgical decompression of median n...

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...

In this study, rats were put into traumatic brain injury-induced coma and treated with median nerve electrical stimulation. We explored the wake-promoting effect, and possible mechanisms, of median nerve electrical stimulation. Electrical stimulation upregulated the expression levels of orexin-A and its receptor OX1R in the rat prefrontal cortex. Orexin-A expression gradually increased with inc...
