Summary
High-resolution 3D micro-CT imaging reveals the complex micro-architecture of the normal odontoid process. This detailed analysis provides valuable insights into bone structure for further biomechanical studies.
Area of Science:
- Orthopedic Surgery
- Radiology
- Biomedical Engineering
Background:
- Odontoid fractures can cause severe instability and spinal cord injury.
- Understanding the normal odontoid's micro-architecture is crucial for fracture management.
Purpose of the Study:
- To analyze the micro-architecture and morphometric parameters of the normal odontoid process.
- To utilize high-resolution three-dimensional (3D) micro-computed tomography (micro-CT) for detailed imaging.
Main Methods:
- Acquired micro-CT scans of five normal odontoid processes.
- Reconstructed 3D images to visualize trabecular bone, nutrient foramina, and ossification centers.
- Measured trabecular bone volume fraction in different regions.
Main Results:
- Obtained high-resolution 3D images of odontoid micro-structures.
- Characterized the odontoid as having sponge-like trabecular bone with a complex, net-like structure.
- Observed significant differences in bone volume fraction between specific regions of the odontoid.
Conclusions:
- High-resolution 3D micro-CT is effective for evaluating normal odontoid micro-architecture.
- The detailed micro-CT images can support future research, including finite element analysis.
- This imaging technique offers a feasible method for in-depth study of odontoid bone structure.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

The normal, a continuous distribution, is the most important of all the distributions. Its graph is a bell-shaped symmetrical curve, which is observed in almost all disciplines. Some of these include psychology, business, economics, the sciences, nursing, and, of course, mathematics. Some instructors may use the normal distribution to help determine students’ grades. Most IQ scores are normally distributed. Often real-estate prices fit a normal distribution. The normal distribution is...

01:19Normal Stress

Normal stress is a type of stress that occurs when forces act perpendicular, or normal, to a material's cross-sectional area. This stress often arises in structures when subjected to axial loading, which is the application of force along the axis of an object. A practical example of this can be found in bridge truss members.
When a rod is under axial loading, the internal forces and corresponding stress are normal to the plane of the section, so it is termed normal stress. It's important to...
