Multiple Variations of the Branches of the Brachial Plexus with Bilateral Connections between Ulnar and Radial Nerves
Provedor de dados: 77
Autores: Ajayi,Nasirudeen Oladipupo; Lazarus,Lelika; Satyapal,Kapil Sewsaran.
During routine dissection of the upper limbs of a Caucasian male cadaver, multiple variations of the branches of the brachial plexus were observed. On the left side, the musculocutaneous nerve was absent and the muscles of the anterior compartment of the arm were innervated by the median nerve. The median nerve was also formed from three roots viz; two from the lateral and one from the medial cord of the brachial plexus. On the right side, the musculocutaneous nerve contributed a long communicating branch to the median nerve in the distal half of the arm. There were also communicating branches between the ulnar and radial nerves in both limbs at the humeral level. The co-existence of these variations appears to be unique and has not been reported in the...

A Communicating Branch between the Dorsal and Superficial Ramus of the Ulnar Nerve (Kaplan's Anastomosis): Clinical and Surgery Discussion
Provedor de dados: 77
Autores: Torre,F; Erthal,R; Fernandes,R. M. P; Babinski,M. A; Cisne,R.
The Kaplan´s anastomosis represents the communication between the dorsal and superficial branch of the ulnar nerve distal to ulnar canal. In the present study, a case about this nerve communication, found in a male adult cadaver, is reported. Information about brachial plexus distal anastomosis is fundamental for interpretation of clinical and electrophysiological findings, in order to establish the precise diagnosis of neurological lesions at this level. Its relations with flexor carpi ulnaris muscle's tendon and with pisiform bone exposes it to iatrogenic lesions during surgery.

Additional Muscle Slip of Flexor Carpi Ulnaris Associated with Anomalous Ulnar Nerve and Ulnar Artery in the Distal Forearm
Provedor de dados: 77
Autores: Ramana Vollala,Venkata; Bhat,Seetharama; Rodrigues,Vincent; Prasad,Deepthinath; Pamidi,Narendra.
During routine dissection classes to under gradúate medical students, we observed an anomalous flexor carpi ulnaris muscle associated with abnormal ulnar nerve and ulnar artery in the distal part of forearm. There was an additional belly arising from the lower part of the flexor carpi ulnaris muscle and crossed ulnar nerve and vessels, median nerve and ended in a broad aponeurosis which crossed the tendons of flexor digitorum superficialis and merged with the deep f ascia and flexor retinaculum. The ulnar nerve and ulnar artery divided into their terminal branches in the lower part of the forearm. However, the distribution of the terminal branches of both ulnar nerve and artery were normal. An understanding of these unusual findings may be clinically...

Supernumerary Fascicle of Abductor digiti minimi Muscle and Compression of Ulnar Nerve and Ulnar Artery: A Case Report
Provedor de dados: 77
Autores: Thejodhar,P; Sampath,K. Madhyastha; Bhagath,Kumar, Potu; Sreedhar,V; Binod,K. T; Chakravarthy,M; Ramana,V; Satish,N.
The supernumerary fascicles of abductor digiti minimi muscle have been implicated in vascular and nerve compression. During routine dissection of an old male cadaver we observed an anomalous muscle was found to take it's origin from the antebrachial fascia and flexor retinaculum, traversed ulnar canal (Guyon's) superficial to ulnar vessels and nerves to reach the proximal part of abductor digiti minimi. The anomaly is one of a kind. Its course through Guyon's canal could be a cause for Guyon's canal syndrome. It was innervated by the ulnar nerve

Connection between Radial and Ulnar Nerves at Humeral Level And Its Clinical Significance: A Cadaveric Case Report
Provedor de dados: 77
Autores: Taheri,Mohammad Mehdi Hassanzadeh; Afshar,Mohammad.
Variations of the terminal branches of the brachial plexus in the upper limb are abundant and frequently have been reported. But connection between its radial and ulnar nerves at humeral level is very rare. During routine dissection of the right arm of a 75-year-old male cadaver in the Department of Anatomy of Birjand University of Medical Sciences (BUMS), in Iran, we observed a connection between radial and ulnar nerves, and from the literature reviewed, we found only two cases that had been reported previously, one of them was unilateral and the other bilateral. Awareness of such variations are very important for surgeons and diminish the possible complication of regional anesthesia and surgical procedures, hence, we decided to report it.

Effect of skilled and unskilled training on nerve regeneration and functional recovery

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)...
