Title : THE MORPHOMETRIC ANALYSIS OF THE LUMBAR VERTEBRAE IN THE IRAQI POPULATION

Abstract :

Persons and nations have slightly varying morphological measures of the lumbar vertebrae. This research intends to improve the safety and efficacy of pedicle screw fixation and the accuracy of CT pedicle measurements. Methods and patients During the year 2020, 60 Iraqi patients (24 males and 36 females) were scanned to study the lumbar pedicles. Axial length, axial angle, pedicle breadth, and endosteal thickness Measurements were considered. According to this research, the axial length of pedicles is approximately 5.5 centimetres at all lumbar levels, with minimal shortening at L4 and L5. The lumbar pedicle axis angles of inclination on the midline are more obtuse than known Western measures, getting more obtuse from L1 to L5. The research revealed that from L1 (8.39 millimetre) to L5 (16.48 millimetres), the pedicel breadth becomes gradually thicker and that the endosteal thickness follows, getting thicker at L5 (4.17 millimetres) than at L1 (11.85 millimetres). All of the above measurements have a statistically significant difference. Conclusion: Pedicle morphometry may be accurately predicted using CT pedicle measurements. The measurements of Iraqi lumbar pedicles differ from those of other populations, according to this study. Finally, the diameter of the pedicle screw, the length of the screw, and the angle at which it is inserted should all be matched to each patient's CT pedicle measurements.
