TL;DR
This paper introduces a new method to measure the transverse pedicle angles of the lower lumbar vertebrae using digital radiography, offering a reliable alternative to traditional imaging techniques.
Contribution
The study presents a novel mathematical algorithm for determining transverse pedicle angles using digital radiography and validates its reliability.
Findings
The AP length/estimated lateral length for L3 showed statistical significance between the right and left sides.
The width and length of the pedicle were consistent with the transverse pedicle angle (L3 < L4 < L5).
The ICCs for real TPA and DR-TPA showed good to moderate reliability across L3-L5 vertebrae.
Abstract
To investigate a novel approach for establishing the transverse pedicle angle (TPA) of the lower lumbar spine using preoperative digital radiography (DR). Computed Tomography (CT) datasets of the lower lumbar were reconstructed using MIMICS 17.0 software and then imported into 3-matic software for surgical simulation and anatomical parameter measurement. A mathematical algorithm of TPA based on the Pythagorean theorem was established, and all obtained data were analyzed by SPSS software. The CT dataset from 66 samples was reconstructed as a digital model of the lower lumbar vertebrae (L3-L5), and the AP length/estimated lateral length for L3 between the right and left sides was statistically significant (P = 0.015, P = 0.005). The AP length of the right for L4 was smaller than that of the left after a paired t test was executed (P = 0.006). Both the width of the pedicle and the length…
