The first step in an investigation of quantitative ultrasound as a technique for evaluating infant bone strength.

This study's purpose is to evaluate whether bone speed of sound (SOS) data, a parameter of quantitative ultrasound, collected from an infant autopsy sample are comparable to data collected from healthy, living infants. We hypothesize that SOS values obtained from deceased term-born infants will fall within the normal range for healthy, living infants. The study sample consists of 351 deceased infants between the ages of 30 weeks gestation at birth to 1 year postnatal at the time of death receiving autopsies at the Harris County Institute of Forensic Sciences or Texas Children's Hospital in Houston, TX.

The Infant Injury Database: A Tool for the Study of Injury Patterns in Medicolegal Investigations of Child Abuse.

In 2012, the Harris County Institute of Forensic Sciences began prospectively collecting injury data from pediatric autopsies. These data and associated case information from 635 pediatric cases are archived in the Infant Injury Database (IID). This paper introduces the IID to the forensic community and demonstrates its potential utility for child abuse and infant fatality investigations.

Recent advancements in the analysis of bone microstructure: New dimensions in forensic anthropology.

Bone is a mechanically active, three-dimensionally (3D) complex, and dynamic tissue that changes in structure over the human lifespan. Bone tissue exists and remodels in 3D and changes over time, introducing a fourth dimension. The products of the remodelling process, secondary and fragmentary osteons, have been studied substantially using traditional two-dimensional (2D) techniques.

Mechanical properties of infant bone.

Although an understanding of bone material properties is crucial for interpreting and predicting fracture patterns due to injury or defining the effects of disease on bone strength, information about infant bone properties is scant in the literature. In this study we present the mechanical testing results from 47 tibia and 52 rib specimens taken from 53 infant decedents in order to further our understanding of infant bone strength. Bone specimens were imaged using microCT and tested in three-point bending until failure.
