Side-to-side discrepancy in range of motion (ROM) during upper limb neurodynamic testing is used in part to identify abnormal peripheral nerve mechanosensitivity and is one of three factors to consider in determining a positive test. Large side-to-side variability is reported for some variants of the upper limb neurodynamic test sequences, however discrepancies for other test variants are unkno...

The purpose of this article is to review the anatomical features of the most common nerve entrapment sites of the brachial plexus and major peripheral nerves of the upper limb. In this account, the term "entrapment" is considered to be caused by compression, tension, or friction, or any combination of these factors. The anatomy, including important relationships of the brachial plexus, is revie...

The digital nerves to the thumb and index finger have been studied by dissecting twenty-five embalmed upper limbs. The palmar digital nerves to the thumb were constant in position and course, with a short lateral cutaneous branch from the radial palmar digital nerve in 30 per cent of cases. The palmar digital nerves to the index finger had a variable pattern, the commonest arrangement, well des...

ltrasonography not only permits a detailed assessment of peripheral nerves but also is useful for intrinsic nerve abnormality detection, as in peripheral nerve enlargement (eg, in trauma, peripheral nerve sheath tumors, and nerve compression). Ultrasonography can also be used to locate nerve compression due to an extrinsic factor (eg, compression of the posterior interosseous nerve by the arcad...

BACKGROUND The ulnar nerve upper limb neurodynamic test (ULNT3) uses upper limb positioning to investigate symptoms arising from the ulnar nerve. It is proposed to selectively increase tension of the nerve; however, this property of the test is not well established. OBJECTIVE The aim of this study was to determine the upper limb position that results in: (1) the greatest tension of the ulnar ...

BACKGROUND The criteria and timing for nerve surgery in infants with obstetric brachial plexopathy remain controversial. Our aim was to develop a new method for early prognostic assessment to assist this decision process. METHODS Fifty-four patients with unilateral obstetric brachial plexopathy who were ten to sixty days old underwent bilateral motor-nerve-conduction studies of the axillary, ...

The end-to-side nerve-repair technique, i.e., when the distal end of an injured nerve is attached end-to-side to an intact nerve trunk in an attempt to attract nerve fibers by collateral sprouting, has been used clinically. The technique has, however, been questioned. The aim of the present study was to investigate end-to-side repair in the upper extremity of rats with emphasis on functional re...

The objective of this study was to reveal the overall distribution pattern hand’s cutaneous nerves provide a morphological basis for selection and matching hand skin sensory reconstruction during flap transplantation. hands 12 adult cadavers were used study. Palmar region dorsum divided into regions I-VI. containing subcutaneous fat removed close muscle surface. modified Sihler’s staining m...

A teased fibre technique was used to study 19 biopsies of the index finger branch of the radial cutaneous nerve of leprosy patients and contacts. These were compared with four normal nerves. Five nerves were from patients with preclinical nerve lesions, five from leprosy patients with minimal sensory nerve impairment, and five from contacts of lepromatous leprosy. The extent of demyelination in...
