Early Adopter Program

Measure The Mechanical Properties of Cortical Bone in Living People

​Proprietary Cortical Bone Mechanics Technology™ makes accurate noninvasive, direct, functional measurements of structural mechanical properties (mass, stiffness, and damping) and calculates the quality factor Q, flexural rigidity (EI) and bending strength (Mpeak) of ulnar cortical bone.

CBMT Scientific Instruments

CBMT™ Model SI-001 Series is now available for order from OsteoDx.

Not a Medical Device

OsteoDx instruments and accessories are not medical devices and are not intended for the diagnosis, cure, mitigation, treatment, or prevention of disease

Our Solution

Direct Functional Measurement of the Mechanical Properties of Cortical Bone


High Accuracy

Results indistinguishable from Quasistatic Mechanical Testing (QMT)


Rapid reproducible results

CBMT devices well suited for research studies because of ease of operation and consistency of results



CBMT Dynamic mechanical analysis ‘sees through’ skin to the bone underneath

Our Cortical Bone Mechanics Technology™

Two product lines for two markets: Scientific Instruments and Medical Devices

Ohio University IRB Approved

  • CBMT scientific instrument for scientific research
  • CBMT medical device for non-significant risk medical research

Mechanical Bending Test

CBMT device performs a non-invasive dynamic mechanical bending test of the mid-shaft of the ulna.

Mechanical Vibration Analysis

Direct functional measures of the mass, stiffness, and damping of cortical bone in living persons

Physiological context

Measures whole bone structure, including protein and mineral

Improved MRTA

CBMT employs proprietary improvements to Mechanical Response Tissue Analysis (MRTA)

Proven technology

CBMT scientific instruments and medical devices have been extensively tested on cadaveric human arms (see article) and human volunteers

Intended for Research Use

OsteoDx's Cortical Bone Mechanics™ instrument SI-001 is suited for investigations of the mechanical integrity of cortical bone in the ulnas of living human subjects (and in cadavers).

Examples of research studies using CBMT™ include:

Observational studies comparing cortical bone mechanics in demographic groups and monitoring changes in cortical bone mechanics over time;

Experimental studies investigating local effects of mechanical loading (i.e., exercise) and systemic effects of nutrition, nutriceutical and pharmaceutical agents.

Basic research in bone biology relating to osteoporosis and other systemic bone diseases and health
