Summary
This study measured lumbar vertebrae pedicle dimensions in Eastern India, revealing significant variations compared to global data. These findings are crucial for improving pedicle screw insertion techniques.
Area of Science:
- Anatomy
- Orthopedics
- Radiology
Background:
- Accurate morphometric data of lumbar vertebrae pedicles is essential for spinal surgery.
- Existing data may not fully represent diverse populations, potentially impacting surgical outcomes.
Purpose of the Study:
- To collect and analyze morphometric data of lumbar vertebrae pedicles in the adult population of Eastern India.
- To compare these measurements with data from other regions globally.
- To identify variations that could influence surgical procedures.
Main Methods:
- A retrospective cross-sectional study utilizing dried lumbar vertebrae and 3D CT scan models.
- Linear and angular measurements of lumbar pedicles were performed bilaterally.
- Data was collected from a 1mm thin CT scan slice of the lumbar spine.
Main Results:
- Transverse pedicle width was widest at L3 and narrowest at L2.
- Sagittal pedicle width was widest at L4 and narrowest at L3.
- Pedicular and body length along the pedicular axis was longest at L5.
- Transverse pedicular angle increased caudally, while sagittal pedicular angle decreased.
Conclusions:
- Significant differences were observed between the study's data and existing literature from other populations.
- The collected morphometric data is beneficial for the success of the free-hand technique of pedicle screw insertion.
