Area of Science:

  • Forensic Anthropology
  • Human Osteology
  • Developmental Anatomy

Background:

  • Accurate age estimation is crucial in forensic anthropology.
  • Cervical vertebrae ossification centers provide developmental markers.
  • Existing methods may be limited with fragmented or isolated remains.

Purpose of the Study:

  • To develop and validate a discriminant function model for classifying human newborn cervical ossification centers.
  • To establish a quantitative method for analyzing cervical neural arch measurements.
  • To aid in the identification of human remains in forensic and anthropological contexts.

Main Methods:

  • Defined nine linear measurements on the cervical neural arch from 35 human neonates.
  • Utilized a stepwise method to perform four discriminant functions.

  • Applied the developed model for classification of ossification centers.

    • Main Results:

    • The discriminant function model achieved 82.8% accuracy in classifying grouped cases.
    • The model demonstrated 77.9% accuracy in cross-validated cases.
    • The measurements and functions were specifically tailored for newborn cervical vertebrae (9-10 months).

    Conclusions:

    • The developed method provides a reliable tool for classifying cervical ossification centers in human newborns.
    • This classification model is particularly useful for anthropological and forensic investigations involving isolated or commingled skeletal remains.
    • The research contributes to the field of forensic age estimation and human identification.
