[Role of computed tomography in the estimation of the density of the bony block of an injured vertebral column segment at different stages of treatment with an external transpedicular fixation apparatus].

A Somatom AR.HP computed tomograph (Siemens) was used to make studies in 54 patients with injury to the vertebral column and spinal cord in order to determine the formation of a bony block and its density in different portions of an injured segment at the stages of treatment. During therapy, the highest values of bony block density were observed in the dorsal portions of an injured segment (mean 377.
