Deciphering the morphometric nuances of lumbar pedicles in a Jordanian population : the diversity

الملخص EN

Introduction:Transpedicular fixation in lumbar spine surgery using pedicle screws has become the standard technique for stabilization of the unstable spine.

However, some complications arise with the introduction of pedicle screws.

Accurate knowledge of pedicle morphometrics and dimension measurements are vital.

To the best of our knowledge, there has been no in-vivo analysis and measurements performed on Jordanian people to evaluate lumbar pedicle morphometrics (width and height) based on CT scans.

Objectives: This study was steered to obtain 2-dimensions measurements of the lumbar pedicle using 2D transverse CT images.

In addition, to examine whether gender might affect these measurements.

Materials and Methods:A retrospective analysis of acquired data conducted by reviewing patients managed at King Hussein Medical Center (KHMC) and their radiology images records.

Patient images retrieved from the electronic hospital database for a 2-year period (2018 - 2020).

Results: This analysis included 50-femalesand 71-males.

The mean age of 42.38±17.40 years for the whole population.

The statistical difference between lumbar pedicle mean horizontal dimension among males and females was significant from L1 to L5 vertebral bodies, showing that horizontal dimension in male group is wider (P< 0.05).

The Same trend was observed between mean lumbar pedicle vertical dimension, showing higher vertical dimensions in male group (P< 0.05).

Conclusion: This novel national study presented comprehensive knowledge for pedicle morphometry and orientation.

It has elucidated gender variations between Jordanian and other populations.
