BACKGROUND Nerve damage after regional anesthesia has been of great concern to anesthetists. Various modalities have been suggested to recognize and prevent its incidence. An understudied area is the measurement of intraneural pressure during peripheral nerve blockade. Previous investigations have produced contradicting results with only one study being conducted on human cadavers. OBJECTIVES...

This 16-year retrospective study reports the data on 456 consecutive patients with 557 peripheral nerve injuries (PNIs) between 1989 and 2004. Most patients were men (74%) and the mean age was 32.4 years. In 83% of cases the PNIs were isolated; combined lesions most commonly involved the ulnar and median nerves. Upper-limb PNIs occurred in 73.5% of cases; the ulnar nerve was most often injured,...

Objective: The purpose of this study was to assess the measurement nerve gliding, resulting from joint motion and changes upper extremity position. Methods: extremities ten fresh human cadavers were dissected delineate relationship between positioning gliding distance nerves. Nerve mobilization – stretching therapy (SMG) techniques are mentioned in literature for each radial, medial ulnar excur...

A model for magnetic stimulation of the radial and sciatic nerves in dogs was evaluated. Onset-latencies and peak-to-peak amplitudes of magnetic and electrical stimulation of the sciatic nerve were compared, and the effect of the direction of the current in the magnetic coil on onset-latencies and peak-to-peak amplitude of the magnetic motor evoked potential was studied in both nerves. The resu...

introduction: lasers, light emitting diodes (leds) and super luminous diodes (slds) are widely used to treat selected musculoskeletal, integumentary and neurological conditions. the mechanisms underlying the reported treatment effects of light therapy are unclear and the physiologic effect of light on a variety of tissues, particularly neurological, is mostly unknown. a few researchers have rep...

Myelin is a multispiraled extension of glial membrane that surrounds axons. How glia extend a surface many-fold larger than their body is poorly understood. Schwann cells are peripheral glia and insert radial cytoplasmic extensions into bundles of axons to sort, ensheath, and myelinate them. Laminins and beta1 integrins are required for axonal sorting, but the downstream signals are largely unk...

Editor’s key points † The hypothesis tested was that the addition of distal nerve blocks to an infraclavicular block would speed up onset. † Infraclavicular block with or without distal blocks of the median, ulnar, and radial nerves were compared using the same total dose of local anaesthetic. † A more rapid onset and more consistent block occurred in the combined group. Background. This prospe...

This clinical study was carried out to compare the rate of nerve complications after anterior and posterior approaches in forearm both bone fractures in adults. For this purpose, 310 patients with forearm both bone fractures operated during 1997-2002 in Kerman Shahid Bahonar Hospital were studied. From these patients, 121 cases werefemale and 189 cases were male and they were aged from 12 to 67...

During routine cadaveric dissection a female cadaver presented rare combination of neurovascular variations. Persistent axis artery with number of anomalous communicating vessels including vas aberrans connecting brachial and radial arteries were observed in right arm. In the left arm, variations in the formation of median and musculocutaneous nerves, high division of common palmar digital nerv...
