Dorsal cutaneous branch of ulnar nerve: an appraisal on the anatomy, injuries and application of conduction velocity studies in diagnosis.
(1/28)
Classical textbooks and recent publications about the anatomy of the dorsal cutaneous branch of the ulnar nerve are revisited and correlated with methods of measurement of its conduction velocity, in order to evaluate the indications and limitations of the procedure. Etiology and pathogenesis of isolated lesions of this nerve branch are discussed. (+info)
Telesales neuropathy.
(2/28)
A case of bilateral ulnar neuropathies caused by overuse of the telephone is described in a 17 year old double glazing salesman. The importance of taking a good occupational history is emphasised and the need for correct staff training and appropriate equipment highlighted. (+info)
Ulnar nerve palsy due to axillary crutch.
(3/28)
A young lady with residual polio, using axillary crutch since early childhood, presented with tingling, numbness and weakness in ulnar nerve distribution of five months duration. Ulnar motor conduction study revealed proximal conduction block near the axilla, at the point of pressure by the crutch while walking. Distal ulnar sensory conduction studies were normal but proximal ulnar sensory conduction studies showed absence of Erb's point potential. These findings suggested the presence of conduction block in sensory fibers as well. Proper use and change of axillary crutch resulted in clinical recovery and resolution of motor and sensory conduction block. (+info)
Intraneural mucoid pseudocysts. A report of ten cases.
(4/28)
A mucoid pseudocyst of a peripheral nerve is a rare and benign tumour of controversial origin. We have reviewed ten patients with a mean follow-up of 3.2 years. The tumour affected the common peroneal nerve in eight and the ulnar nerve in two. The mean time between the onset of symptoms and diagnosis was 7.4 months (1.2 months to 2 years). On examination, there was pain in eight patients and swelling in seven. Motor deficit in the corresponding nerve territory was found in all. The diagnosis was usually confirmed by MRI. Treatment was always surgical. All the patients recovered, with a mean time to neurological recovery of 10.75 months. Recurrence was seen in only one patient and was treated successfully by further surgery. Our results are similar to those reported by other authors. A successful surgical outcome depends on early diagnosis before neurological damage has occurred. (+info)
Compression neuropathy of the ulnar nerve. A common condition occurring at bed rest.
(5/28)
Compression neuropathy of the ulnar nerve at bed rest appears to be quite common. The symptoms are dysesthesia, weakness and later atrophy in the area of distribution of the nerve. Special attention is required for prevention or for early discovery of the condition in time for treatment to bring about prompt recovery. Physical therapy with electrical stimulation may be useful in the more severe cases. When the condition is progressive or recalcitrant, anterior transplantation of the nerve may be necessary. (+info)
Incidence of common compressive neuropathies in primary care.
(6/28)
Apart from carpal tunnel syndrome, there are no population based studies of the epidemiology of compressive neuropathies. To provide this information, new presentations of compressive neuropathies among patients registered with 253 general practices in the UK General Practice Research Database with 1.83 million patient years at risk in 2000 were analysed. The study revealed that in 2000 the annual age standardised rates per 100 000 of new presentations in primary care were: carpal tunnel syndrome, men 87.8/women 192.8; Morton's metatarsalgia, men 50.2/women 87.5; ulnar neuropathy, men 25.2/women 18.9; meralgia paraesthetica, men 10.7/women 13.2; and radial neuropathy, men 2.97/women 1.42. New presentations were most frequent at ages 55-64 years except for carpal tunnel syndrome, which was most frequent in women aged 45-54 years, and radial nerve palsy, which was most frequent in men aged 75-84 years. In 2000, operative treatment was undertaken for 31% of new presentations of carpal tunnel syndrome, 3% of Morton's metatarsalgia, and 30% of ulnar neuropathy. (+info)
Nerve conduction studies and current perception thresholds in workers assessed for hand-arm vibration syndrome.
(7/28)
BACKGROUND: Workers exposed to hand-arm vibration are at risk of developing the neurological abnormalities of hand-arm vibration syndrome (HAVS). The Stockholm classification of the neurological component of HAVS is based on history and physical examination. There is a need to determine the association between neurological tests and the Stockholm scale. AIMS: The main objective of this study was to compare the Stockholm neurological scale and the results of current perception threshold (CPT) tests and nerve conduction studies (NCS). METHODS: Detailed physical examinations were done on 162 subjects referred for HAVS assessment at a specialist occupational health clinic. All subjects had NCS and measurement of CPT. The Stockholm neurological classification was carried out blinded to the results of these neurological tests and compared to the test results. RESULTS: The nerve conduction results indicated that median and ulnar neuropathies proximal to the hand are common in workers being assessed for HAVS. Digital sensory neuropathy was found in only one worker. Neither the nerve conduction results nor the current perception results had a strong association with the Stockholm neurological scale. Exposure to vibration in total hours was the main variable associated with the Stockholm neurological scale [right hand: OR 1.30, 95% CI (1.10-1.54); left hand: OR 1.18, 95% CI (1.0-1.39)]. CONCLUSION: Workers being assessed for HAVS should have nerve conduction testing to detect neuropathies proximal to the hand. Quantitative sensory tests such as current perception measurement are insufficient for diagnostic purposes but may have a role in screening workers exposed to vibration. (+info)
Biomechanics of the elbow joint in tennis players and relation to pathology.
(8/28)
Elbow injuries constitute a sizeable percentage of tennis injuries. A basic understanding of biomechanics of tennis and analysis of the forces, loads and motions of the elbow during tennis will improve the understanding of the pathophysiology of these injuries. All different strokes in tennis have a different repetitive biomechanical nature that can result in tennis-related injuries. In this article, a biomechanically-based evaluation of tennis strokes is presented. This overview includes all tennis-related pathologies of the elbow joint, whereby the possible relation of biomechanics to pathology is analysed, followed by treatment recommendations. (+info)
