Abstract:
Authors examined 51 tunnel-miners because of suspicion of hand-arm
vibration syndrome. Vibration measurements were also performed on the drilling
hammer used by the workers. The acceleration of the vibration exceeded
2.5–3.5 times the maximum allowable level according to the guideline ISO
5349. Symptoms and signs referring to hand-arm vibration syndrome were
found in 42 cases. (82.3%). X-ray alterations of bones and joints were
detected in 28 patients (54.9%). In addition of degenerative changes (25
cases; 49%) also aseptic necroses were rather frequent (8 cases; 15.7%).
Vascular damage was shown in 27 patients (54.0%), but peripheral neurological
injury in 18/37 cases (48.6%). The rather common occurrence of damages
of bones and joints and tunnel syndromes respectively can be explained
probably in additon to the vibration also by the high physical stress required
by this profession.
