A technique for CT control of rod position in transpedicuiar fixation of spine fractures

The position of 280 transpedicuiar rods was studied by the method of CT tomography to control their proper insertion. As a result of CT studies it was revealed that 25 rods (8,9%) were positioned paravertebrally 19 rods (6,8%) were determined in the spinal canal. 13 rods were on the left, 6 ones - on the right. Three groups of patients were singled out by the degree of penetration of rods into the spinal canal: Degree 1: the rod dislocation to the spinal canal of up to 0,4 cm; Degree 2: the rod dislocation to the spinal canal of up to 0,7 cm; Degree 3: the rod dislocation to the spinal canal of more than 0,7 cm. Neurosurgeons undertook different tactics for patient management depending on the degree of inserting the rod into the spinal canal.
