BACKGROUND AND OBJECTIVE: Having the correct anatomical points and the size of the pedicle dimension is necessary to minimize neurological complications. Currently, the gold standard for spinal fusion is the use of pedicle screws. In this method, the pedicle screw should be placed in its ideal position. Given the importance of this topic, the present study was performed to determine the dimensions of right and left pedicle by computed tomography (CT) scan in three axial, coronal and sagittal planes based on gender in Fars-native ethnic group.
METHODS: This cross-sectional study was performed on 40 patients (20 females and 20 males aged 18 – 45 years) from Fars-native ethnic group. The average height for males was 165 to 180 cm and for females between 165 and 175 cm. Healthy vertebrae were selected in people who referred to a CT scan unit with symptoms of spinal pain or trauma. Determination of height, length and width of right and left pedicle of lumbar vertebrae in axial, coronal and sagittal view in 1.5 mm sections was performed by CT scan.
FINDINGS: Mean and standard deviation of height (1.458±0.141), width (0.788±0.173), and length (1.248±0.195) of pedicle in men (based on millimeter) was significantly higher compared to mean and standard deviation of height (1.268±0.140), width (0.618±0.148), and length (1.08±0.174) in women (p<0.05).
CONCLUSION: The results of this study showed that gender affects the dimensions of lumbar vertebral pedicle. |
