Summary
Ponticulus posticus (PP) is a common anomaly found in 36.8% of Turkish individuals, identified via cervical 3-D CBCT scans. This finding has implications for upper cervical spine procedures.
Area of Science:
- Anatomy
- Radiology
- Medical Imaging
Background:
- Ponticulus posticus (PP) is an anatomical variation of the atlas vertebra.
- Its prevalence and characteristics are not fully understood across all populations.
Purpose of the Study:
- To determine the prevalence and morphological types of ponticulus posticus.
- To analyze demographic variations in ponticulus posticus occurrence using 3-D CBCT.
Main Methods:
- Retrospective analysis of 698 cervical 3-D CBCT scans.
- Evaluation for the presence, type (complete/partial, bilateral/unilateral), and side of ponticulus posticus.
Main Results:
- Ponticulus posticus was identified in 36.8% of patients (257 out of 698).
- Bilateral complete PP occurred in 6.3% and partial PP in 16.2%.
- Significant differences in prevalence were noted between sexes, but not age groups.
Conclusions:
- Ponticulus posticus is a relatively common anatomical anomaly in the studied Turkish population.
- The prevalence and variations of PP may impact clinical procedures involving the upper cervical spine.

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

01:14Cranial Bones: Superior and Posterior View
8.6K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
