Morphometric Study of the Atlas Vertebra in Madhya Pradesh Population: 3D CT-Based Analysis and Its Surgical Significance in Craniovertebral Junction
Researchers often face challenges during surgeries at the craniovertebral junction (CVJ). The atlas vertebra (C1) plays a key role in this region. Therefore, precise knowledge of its dimensions helps surgeons plan safe procedures.
This study examines the morphometry of the atlas vertebra in the Madhya Pradesh population. Investigators collect 3D CT scan data from adult patients. They measure important parameters such as the width and height of the lateral masses, dimensions of the superior and inferior articular facets, anteroposterior and transverse diameters of the vertebral canal, and thickness of the posterior arch.
First, the team selects normal CT scans without any congenital anomalies or fractures. Next, they use advanced 3D reconstruction software to take accurate measurements. They also record variations in the vertebral artery groove and transverse foramen. Moreover, they compare the data between male and female subjects as well as between right and left sides.
The analysis applies statistical tools to calculate mean values, standard deviations, and ranges. In addition, the study identifies population-specific differences. These differences arise because anatomical features vary across ethnic groups.
Surgeons use lateral mass screws or transpedicular fixation during CVJ stabilization. However, inaccurate screw placement can injure the vertebral artery or spinal cord. This research provides reference values for the local population. As a result, surgeons can choose better screw sizes and trajectories. Consequently, the risk of complications decreases during posterior fixation procedures.
Furthermore, the findings support preoperative planning in cases of trauma, rheumatoid arthritis, or congenital malformations at the CVJ. Hospitals in Central India can apply these norms directly. In the long run, the data improves surgical safety and patient outcomes.
This study adds valuable information to existing literature on Indian populations. It also encourages future research that combines 3D CT morphometry with clinical results.
