X ray anomalies occurring in workers exposed to vibration caused by light tools.
نویسندگان
چکیده
A high frequency of radiological anomalies (vacuoles, cysts, enostoses) was found in workers exposed to vibration caused by light tools (screw drivers, nutrunners) compared with a non-exposed group. The lesions were mostly localised in the spongy carpal bones (os capitatum, os lunatum, os scaphoideum). There was no significant difference between the sexes, nor between the "active" or "passive" hand, both hands being simultaneously exposed. These findings support the need to implement preventive measures.

Haemostatic function and neurovascular symptoms were investigated in 67 workers exposed to vibration and 46 comparable referents. Of these 65.6% of vibration workers complained of neurological disturbances (stages 0T, 0N of Taylor's classification for vibration induced white finger (VWF) and 20.9% suffered from Raynaud's phenomenon (stages 1-2-3). The severity of the staging symptoms showed a c...
