Symptoms and musculo-skeletal changes among personnel of the State Police exposed to mechanical risk

The aim of this present study was to inquire about spine morfo-functional alterations among policemen with jobs regarded as potentially hazardous, in order to identify preclinical alterations of column and to plan adequate preventive measures. A physiopathologic and working anamnesis was carried out by means of questionnaire about personal data, jobs, reported rachidian symptomatology and presence of orthopedic diseases, given to policemen on duty in Bari. Every chosen worker was subject to orthopedic and neurological examination, radiography of column, Formetric tridimensional examination, telethermography of spine. We stratified the sample on the basis of age and job. Under the jobs we individuated 4 biomechanical hazardous activities, performed separately or together: driving motorcycle, driving car, flying helicopter, video terminal use. The whole sample, formed by 211 subjects, all male, had the average age of 39 years (Standard Deviation: +/- 4). About the reported rachidian symptomatology, only 41 (17, 98%) subjects were asymptomatical, contrary to clinical results, that were normal in almost the entire sample, with the exception of 3 workers (1, 31%), who had neurological clinical alterations. Structural alterations were checked by radiography among 64, 9% of subjects. The Formetric examination found alterations in different tract of rachis, also coexiting between each other. The telethermographic changes affected 63,99% of the sample and involved especially the lumbar tract (38,86%), dorsal region (18%) and cervical zone (7,1%). The relative frequency of dorsal tract increased with growing of age. The morfo-functional changes of the sample seem to depend rather on the performed job, than on degenerative process of age, partly because the average age of the sample is not much elevated and because the enlistment in Italian Police Force is subordinated to verification of optimum conditions, also characterized by absence of anomaly of column. The absence of clinical alteration, in contrast to reported rachidian symptomatology by 82,02% of subjects and with discovered objectivity, demands more clinical attention in presence of symptomatology and proposes supplementary non-invasive techiniques of investigation, as the telethermography and the formetric tridimensional examination.
