[Experimental studies of the load capacity of the supravital cervical spine]

The relative bearing power of fresh cervical vertebrae was found out in 105 single examinations. The vertebrae were descended from 21 vertebral columns of 11 male and 10 female individuals. A plane-parallel embedding of the vertebrae was necessary for the pressure experiments. The investigations were put through with a tester from the VEB Prüfmaschinen-werk Leipzig The tester was fitted out with a 200 kp measuring box. The transducer was a semi-conductor with a key tack. The relative bearing power of fresh cervical vertebrae lay between 32,1 kp/cm2 and 89,7 kp/cm2. The statistic analysis was carried out with a microprocessor. It was found out a relation between relative bearing power and height. The further analysis took place in 3 groups which were determined by the height. We pointed out that the vertebrae of cervical vertebral column binding have a different bearing power. The vertebrae of the inferior cervical column in men with more than 1,80 m height have a higher relative bearing power but in men under 1.69 m the vertebrae of the middle vertebral column have the higher relative bearing power.
