The left vertebral pedicles (L2-L4), right vertebral pedicles (L1-L5), and right transverse processes (L1-L5) were identified by C-arm fluoroscopy and marked with 25-gauge needles (0.7 mm diameter, 38 mm length; Becton Dickinson, S.A., Spain).
(1,2) By radiograph, type IA differs from type IB in the presence of rib fractures and the absence of ossification of vertebral pedicles. By histology, type IA is characterized by inclusion bodies in chondrocytes, and the cartilage matrix is close to normal; in type IB, the cartilage matrix is distinctly abnormal, showing rarefaction of the ground substance and a peculiar ringlike pericellular arrangement of collagen fibers.
Afterwards, pedicle screws were implanted inside the upper and lower normal vertebral pedicles adjacent to the injured vertebra in an herringbone position.4 Then laminectomy was performed for the injured vertebra to explore compression to the ventral aspect of the spinal cord, and the fractures that intruded into the spinal canal were restored forward with an L-shaped push rod to relieve such compression.
Although the spinous process is well defined as 3D coordinates and vertebral pedicles neighbourhood, the problem of determining the reference points of the guiding system and the minimal number of supporting points is very important for ensuring a high precision of the screw implant.
