The diagnosis of brachial plexus avulsion is often delayed by concomitant trauma to the arm and shoulder. Therefore, nerve transfer surgery restore elbow shoulder function rarely reported. We present our initial experience double fascicular for upper avulsion. A 26-year-old male patient presented with a 5-month history unresolving pain paralysis involving his left following motorcycle accident....

Proper knowledge of muscular variations is essential for both anatomists and surgeons. Variations of the flexor carpi ulnaris (FCU) are not very common. We are reporting an unusual case of FCU muscle with two bellies. The two heads (ulnar and humeral) of the muscle continued as two separate bellies and the tendons of which joined each other slightly proximal to the wrist before getting inserted...

INTRODUCTION Dislocation/subluxation of the Extensor Carpi Ulnaris (ECU) tendon is a rare condition in the general population, but is a common problem among athletes that subject their wrists to forceful rotational movements. Pain and snapping sensation at the dorsoulnar aspect of the wrist especially during supination are the predominant symptoms that often necessitate surgical intervention. ...

BACKGROUND AND PURPOSE Positioning a computer keyboard with a downward slope reduces wrist extension needed to use the keyboard and has been shown to decrease pressure in the carpal tunnel. However, whether a downward slope of the keyboard reduces electromyographic (EMG) activity of the forearm muscles, in particular the wrist extensors, is not known. SUBJECTS AND METHODS Sixteen experienced ...

The aim of this paper is to propose an exploratory study on simple, accurate and 19 computationally efficient movement classification technique for prosthetic hand application. The 20 surface myoelectric signals were acquired from 2 muscles – Flexor Carpi Ulnaris and Extensor Carpi 21 Radialis of 4 normal-limb subjects. These signals were segmented and the features extracted using a 22 new comb...

BACKGROUND The aim of this study was to elucidate the morphological charac-teristics of the muscle bundles of the flexor digitorum superficialis (FDS) attached to the intermuscular aponeurosis (IMA) and any related structure that could potentially compress the ulnar nerve. MATERIALS AND METHODS Fifty embalmed limbs of 34 adult cadavers were studied. RESULTS The FDS arose as multiple separat...

Forelimb trajectory and the activity of eight muscles operating at the elbow, wrist and digit joints were analyzed during contact placing (CP) reactions elicited by tactile stimuli applied to the lateral (L) or medial (M) side of the cat's forepaw to verify whether a common movement strategy was used in these reactions. A tactile stimulus applied to the lateral side of the paw led, most frequen...
