Enabling clinicians to directly quantify bone quality

OsteoProbe® is a portable handheld impact microindenter that measures the ability of bone material to resist indentation. Unlike radiological or imaging methods (X-ray, DXA and CT) that measure bone mineral density and bone mineral structure, OsteoProbe® measures bone material quality, which is an independent component of bone strength. OsteoProbe® is for research use only in the United States.

OsteoProbe® uses Reference Point Indentation (RPI) technology to investigate the bone material’s ability to resist a localized force (resist separation of mineralized collagen fibrils). This is quantified by the Bone Material Strength index (BMSi) or Bone Score™.

How OsteoProbe Quantifies Quality

OsteoProbe® utilizes a needle-like tip specifically designed for making subcutaneous measurements without the need for an incision. The tip penetrates through the soft tissue down to the bone surface where it establishes a localized reference point. Once a preload threshold is reached, OsteoProbe automatically triggers a second actuation of higher force that performs the official measurement. Indentation depth as a function of force is recorded and then normalized to a calibrated reference material to calculate a Bone Score™.

What is the Bone Score?

Once a patient is measured, the device displays that patient's Bone Score™.

The Bone Score™ is an easy to understand scale that ranges from 40 to 100.

Since this technique is still very new, a healthy reference interval is being established to help guide physicians with their decision making. Once established by the clinical research community, patients will be ranked in four categories based on the numerical output:

  • Above Average
  • Average
  • Decreased
  • Low

Clinical research is ongoing to accurately define the healthy reference interval for the Bone Score™.

How do you use OsteoProbe?

OsteoProbe uses a single-use sterilized tip to measure bone material quality without an incision. The measurement process is straight forward:

Step 1 - Apply local anesthetic

Percutaneous measurements are made at the mid-shaft of the left or right tibia. After cleaning the region, apply a local anesthetic to numb the skin and periosteium.

Step 2 - Perform measurement

Insert through skin

Place a single-use sterilized tip on the OsteoProbe and insert through the skin to the tibia surface.

Compress housing

Compress the outer housing of the OsteoProbe.

Impact the bone

When fully compressed, the device impacts the bone at a constant force and measures the indentation distance increase from the impact.

Step 3 - Measure reference material

After the software indicates measurements on the patient are complete, measure the reference material that was provided with the single-use tip to calculate the patient's Bone Score™.

Clinical Evidence and Research

OsteoProbe has been extensively tested in clinical research studies covering a wide range of indications. As the technique becomes more common, further refinement and improvement of the test will be possible.
