The most disabling aspect of human peripheral nerve injuries, the majority of which affect the upper limbs, is the loss of skilled hand movements. Activity-induced morphological and electrophysiological remodeling of the neuromuscular junction has been shown to influence nerve repair and functional recovery. In the current study, we determined the effects of two different treatments on the functional and morphological recovery after median and ulnar nerve injury. Adult Wistar male rats weighing 280 to 330 g at the time of surgery (N = 8-10 animals/group) were submitted to nerve crush and 1 week later began a 3-week course of motor rehabilitation involving either "skilled" (reaching for small food pellets) or "unskilled" (walking on a motorized treadmill)... |

The rat models currently employed for studies of nerve regeneration present distinct disadvantages. We propose a new technique of stretch-induced nerve injury, used here to evaluate the influence of gabapentin (GBP) on nerve regeneration. Male Wistar rats (300 g; n=36) underwent surgery and exposure of the median nerve in the right forelimbs, either with or without nerve injury. The technique was performed using distal and proximal clamps separated by a distance of 2 cm and a sliding distance of 3 mm. The nerve was compressed and stretched for 5 s until the bands of Fontana disappeared. The animals were evaluated in relation to functional, biochemical and histological parameters. Stretching of the median nerve led to complete loss of motor function up to... |

During routine dissection, an unusual formation of median nerve was detected in the right upper limb of a 55 year old male cadaver. The median nerve had an additional contribution from lateral cord. The two branches of the lateral cord designated as upper and the lower branches were observed at different levels. The upper branch was in close contact with the third part of the axillary artery and it crossed the vessel anteriorly to unite with a branch of the medial cord to form the median nerve. The median nerve thus formed was related medially to the axillary artery (instead of the normal position of being anterolateral). The median nerve descended below and was joined by an additional lower branch from the lateral cord. Interestingly, the ulnar nerve... |

Variations of the peripheral nerve formation, communication and distribution are clinically important because such knowledge can be used for proper planning of surgeries and evaluating effects of nerve injuries and clinical imaging. Median nerve is known to have several such variations. However studies done on median nerve in Sri Lankan subjects are spars. The objective of this study was to find out anatomical variations of the median nerve with regards to its variations in roots and relations to the arteries in the axilla and arm. The study was done using 98 upper limbs of 49 formalin fixed cadavers. They were dissected and anatomy of the median nerve formations was studied focusing its variations of the roots and relation to the arteries. Anatomical... |

The aim of this study was to examine the change in median nerve location according to forearm movement. Thirty fresh specimens from 15 adult Korean cadavers (10 males and five females; age range, 5391 years) were examined. We measured the motor entry point according to normal and pronated positions of the forearm. The x and y coordinates of the first motor entry point (MEP) in the normal position were 1.6±0.6 cm and 2.8±1.3 cm, respectively. The depth of the MEP was 1.5±0.3 cm. The x and y coordinates of the second MEP were 1.3±0.3 cm and 4.7±1.7 cm, respectively. The depth of the MEP was 1.4±0.2 cm. The x and y coordinates of first MEP with the forearm in the pronated position were 1.9±0.7 cm and 2.3±0.8 cm. respectively. The depth of the MEP was 1.7±0.4... |

Variations in the brachial plexus and the distribution patterns of its branches are not uncommon. A communicating branch, which is the most frequent variation, often arises from musculocutaneous nerve to median nerve. However, the branches arising from lateral cord of the brachial plexus and median nerve instead of musculocutaneous nerve are very rare. Detailed description of the abnormalities is important for surgical procedures. Our case study reports the musculocutaneous nerve was absent, a branch from the medial cord innervated the coracobrachialis muscle and two branches from the median nerve innervated the biceps and brachialis muscles, respectively. Moreover, the median nerve gave off the lateral antebrachial cutaneous nerve. This report provides... |
