Riveting Hammer Vibration and Nerve Damage
Hand Arm Vibration Syndrome (HAVS) is an occupational disease affecting 50% of riveting hammer operators after 10 years of work. Current international standards (ISO 5349) seeking to protect workers from occupational vibration are not effectively predicting HAVS onset. Scarce research has been done which investigates the long term effects of riveting hammer vibration exposure and nerve regenera...
متن کاملTherapeutic Management of Hypothenar Hammer Syndrome Causing Ulnar Nerve Entrapment
Introduction. The hypothenar hammer syndrome is a rare traumatic vascular disease of the hand. Method and Materials. We report the case of a 43-years-old man with a painful tumefaction of the left hypothenar region. The ulnar artery appeared thrombosed clinically and radiologically. The patient underwent surgery to resolve the ulnar nerve compression and revascularise the artery. Results. The s...
متن کاملThe stomatopod dactyl club: a formidable damage-tolerant biological hammer.
Nature has evolved efficient strategies to synthesize complex mineralized structures that exhibit exceptional damage tolerance. One such example is found in the hypermineralized hammer-like dactyl clubs of the stomatopods, a group of highly aggressive marine crustaceans. The dactyl clubs from one species, Odontodactylus scyllarus, exhibit an impressive set of characteristics adapted for survivi...
متن کاملJoining of Cold-Reduced Carbon Steel Sheet and Aluminum Sheet by Impulsive Riveting Method and Punch Riveting Method
The impulsive riveting method is described as the punching and joining of sheet metal carried out using the impulsive energy of a weight accelerated by an air compressor. Parts are held together between the rivet and rivet-holder. A hole is made in the sheets by the high speed collision of rivet and a weight (approximately 100 m/s or more). Another method, punch riveting, joins the sheets by pr...
متن کاملAcute effects of vibration from a chipping hammer and a grinder on the hand-arm system.
OBJECTIVES The purpose of this study was to compare various effects on the hand-arm system of vibration exposure from a chipping hammer and a grinder with the same frequency weighted acceleration. Grip and push forces were measured and monitored during the exposure. The various effects were: muscle activity (measured with surface electrodes), discomfort ratings for different parts of the hand-a...
