Relationship between Pedicle and Transverse Process in Thoracic and Lumbar Vertebrae / 中国康复理论与实践

ABSTRACT

@#Objective To investigate the relationship between the pedicle and the transverse process in the thoracic and lumbar verte-brae. Methods 111antertior-posterior images of the lumbar vertebra and 111antertior-posterior images of the thoracic vertebra were chosen and lines were drawn between two pedicle centers of the same segment. The transverse process was divided into 4 equal parts by horizontal lines. The corresponding study was performed on the relationship between the pedicle and the transverse pro cess. Results Most of the T1～T2 pedicles corresponded to the midline of the transverse process. A large number of the T3～T11 pedicles corresponded to the upper 1/3 of the transverse process and the others corresponded to the upper margin, upper 1/4 or the midline of the transverse process. Most of the T12 pedicles corresponded to the upper margin of the transverse process. A large number of the L1, L2 and L5 pedicles corresponded to the upper 1/3 of the transverse process. A large number of the L3 and L4 pedicles corresponded to the midline of the transverse process. Conclusion The thoracic and lumbar pedicles have a multiform corresponding relationship with the transverse process.
