A technique for recording evoked sensory potentials from the radial nerve has already been reported by us (Downie and Scott, 1964). This technique, although reliable, is time consuming and occasionally difficult and the amplitude of potentials may be as low as 1 to 2 microvolts. The purpose of this communication is to describe a simpler technique by which potentials of greater amplitude can be ...

The hand can be anesthetized effectively with blocks of the median, ulnar, or radial nerve. Each digit is supplied by four digital nerves, which can be blocked with injections on each side of the digit. Anterior or posterior ankle blocks can be used for regional anesthesia for the foot. The anterior ankle block, which is used for procedures on the dorsum of the foot, involves blocking the saphe...

A four-headed biceps brachii muscle and three-headed coracobrachialis muscle, high-originated radial artery and communication between the median and musculocutaneous nerves have been well documented in the available literature. However co-existence of these variations is rare. In this study we aimed to describe multiple variations in the upper limb and discuss their co-existence from clinical a...

Patients with Colles' fractures have serious complications more frequently than is generally appreciated. A study of 565 fractures revealed 177 (31 per cent) with such complications as persistent neuropathies of the median, ulnar, or radial nerves (forty-five cases), radiocarpal or radio-ulnar arthrosis (thirty-seven cases), and malposition-malunion (thirty cases). Other complications included ...

Gray (see Robertson (9, Fig. 25)) has observed the presence of a radial structure in the myelin sheaths of peripheral nerves, but so far this appears to be the only record of such a component. The purpose of the present article is to describe the occurrence and characteristics of a similar radial component in myelin sheaths from the optic nerves of rats, mice, and toads (Xenopus laevis). These ...

BACKGROUND AND AIM The diagnosis of peripheral diabetic neuropathy is based on clinical examination. Nerve conduction study (NCS) enables earlier diagnosis, but it is demanding and requires specialised personnel. In an attempt to simplify the procedure, this study aimed to identify a new electrophysiological index, which might correlate with results obtained on standardised NCS in patients with...

A vessel connecting the axillary or brachial artery to one of the forearm arteries was found in a 65 year old male cadaver, during the gross anatomy dissection of the upper extremity of 20 adult cadavers at the Department of Cellular Biology and Anatomy, Louisiana State University Medical Center. The right radial artery originated from the brachial artery nearly at the usual level and was conne...

BACKGROUND The aim of this study was to describe topographic variations in the arrangement of the four main brachial plexus nerves at the junction of the axilla and the upper part of the arm. METHODS In 153 patients undergoing upper arm surgery using axillary block, we studied nerve arrangements with a three-step approach, combining: (A) cross-sectional ultrasound imaging using a 12 MHz linea...

Objectives: Repetitive microtrauma or overuse injuries may often affect upper extremities of the long term computer users. The aim of this study was to compare sensory nerve conduction velocities (SNCV) for median, radial and ulnar nerves in the wrist of computer users with the same parameters in controls who do not use computers regularly. Material and Methods: Twenty one male computer users (...

The major blood vessels of the ostrich wing were studied by dissection of the wings of 8 ostriches. The axillary artery entered the caudo-ventral aspect of the wing and divided into the brachial and deep brachial arteries. The deep brachial artery gave rise to the radial and ulnar collateral arteries which supplied the caudodorsal aspect of the brachium. The brachial artery divided in the cubit...
