Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Summary

This summary is machine-generated.

A new automated method determines the Paediatric Bone Index (PBI) from hand radiographs for children's bone age assessment. This PBI offers high precision (1.42%) and minimal standard deviation (7.5%) for reliable bone mass measurement.

Area of Science:

Radiology
Pediatrics
Biomedical Engineering

Background:

Routine hand radiographs are used for assessing children's bone age.
Existing radiogrammetry indices for bone mass have limitations.
A computerized method for bone mass determination in children is presented.

Purpose of the Study:

To develop an automated method for determining a Paediatric Bone Index (PBI) from hand radiographs.
To establish a precise and reliable index for pediatric bone mass assessment.
To facilitate retrospective research on bone health in children.

Main Methods:

Inclusion of 1,867 Danish and 531 Dutch children aged 5-19.
Comparison of historical bone mass indices (metacarpal index, DXR-BMD, Exton-Smith) with novel indices.
Derivation and validation of the preferred index using longitudinal X-rays from 20 Japanese children.

Main Results:

The Paediatric Bone Index (PBI), defined as A/(W(1.33) L(0.33)), was identified as the preferred index.
The PBI demonstrated a minimal relative standard deviation of 7.5%.
The precision of the PBI measurements was determined to be 1.42%.

Conclusions:

The automated PBI determination method enhances pediatric bone age assessment.
The PBI facilitates retrospective studies correlating bone mass with fracture incidence and adult bone density.
This method supports the BoneXpert system for automated bone age determination.
