Abstract

Background

This study investigated the angulation of the odontoid process in a South African skeletal population to establish normative vertical angulation in the sagittal plane and assess variations across population affinity groups, biological sexes, and age categories. The study also investigated standardizing techniques for measuring the angle of the odontoid process.

Methods

A cross-sectional study was conducted on 200 cervical axis vertebrae from the Raymond A. Dart Collection. Angulation measurements were taken using digital photographs, ImageJ software and statistical analyses (one-way ANOVA and t-tests).

Results

The mean odontoid process angulation (degrees; °) across the sample was 60.45° (±3.10°). No statistically significant differences in angulation were found. Minor variations were observed, with males (60.77° ± 2.94°) showing a slightly higher mean angulation than females (60.08° ± 3.25°). The age groups, “20–40 years” (60.71° ± 3.56°) and “41–55 years” (60.43° ± 3.04°), displayed greater angulation than the 56–70 years age group (60.19° ± 2.68°). Population affinity groups showed that the Black African group had a mean angulation of 60.57° (±3.01°), the White group had 60.06° (±3.04°), and the Coloured group had a slightly higher mean of 60.64° (±3.26°).

Conclusions

The study concluded there are statistically insignificant differences in the odontoid process angulation based on population affinity, sex, and age. The findings contribute to a better understanding of cervical spine anatomy and assist in clinical interventions related to the cervical spine.

期刊介绍： Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
