[The prevalence of spondylopathies among the crane operators in the port of Venice]. / Prevalenza di spondilopatie tra i gruisti del porto di Venezia.

A group of 78 crane operators were examined using the "EPM Research Unit" method for assessing spine function. Crane operators work in a fixed posture characterized by a flexed position of the cervical spine, isometric load of the extensor cervical muscles and increased dorsal kyphosis. The prevalence of spinal disorders was 39.7% for the cervical tract, 37.2% for the dorsal tract and 38.5% for the lumbar region. The results were compared with those concerning a control group. A statistically significant difference was found in the number of cervical and dorsal complaints (O.R. = 3.33 and 2.69), whereas the difference was nearly significant for the lumbar tract (O.R. = 1.65). The results suggest that this category of workers may be subject to an increased risk for the spine.
