An interventional study of Reference Point Indentation in Distal Radius Fracture, Osteoporosis and Hip Fractures, sponsored by Beth Israel Deaconess Medical Center. Active, not recruiting at 1 site in United States. Open to participants aged 50 Years to 100 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-10-28.

The objective of this study is to determine whether a new minimally invasive method for in vivo measurement of cortical bone tissue properties can identify those who are at risk for fragility fractures of the hip and radius. The investigators hypothesis is that women with fragility fractures of the hip and radius have altered cortical bone tissue properties compared to non-fracture controls independent of standard clinical tests, such as bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA).
The objective of this study is to determine whether a new minimally invasive method for in vivo measurement of cortical bone tissue properties can identify those who are at risk for fragility fractures of the hip and radius. The investigators hypothesis is that women with fragility fractures of the hip and radius have altered cortical bone tissue properties compared to non-fracture controls independent of standard clinical tests, such as BMD. To test these hypotheses, The investigators propose two aims:
Aim 1: Compare cortical bone tissue properties as assessed in vivo by reference point indentation in women with hip fractures and non-fracture controls.
The investigators will compare cortical bone tissue material properties, as assessed by novel in vivo indentation at the mid-tibia in postmenopausal women with recent hip fractures (n) and age-similar controls without fractures (n=). In addition to in vivo indentation measurements, The investigators will assess hip and spine BMD by DXA; as well as other factors that may influence risk of fractures (e.g, vit D status, medication use and physical activity). Hypotheses: Postmenopausal women with hip fractures will have worse bone tissue material properties compared to non-fracture controls even after adjustment for BMD and other potential confounders.
Aim 2: Compare cortical bone tissue properties as assessed in vivo by reference point indentation in women with distal radius fractures to non-fracture controls.
The investigators will compare cortical bone tissue material properties, as assessed by novel in vivo indentation at the mid-tibia in postmenopausal women with recent distal radius fractures (n) and age-similar controls without fractures (n=). In addition to in vivo indentation measurements, The investigators will assess hip and spine BMD by DXA; as well as other factors that may influence risk of fractures (e.g, vit D status, medication use and physical activity). Hypotheses: Postmenopausal women with distal radius fractures will have worse bone tissue material properties compared to non-fracture controls even after adjustment for BMD and other potential confounders.
Successful completion of this project will address the need to better assess bone mechanical properties at the tissue level in order to accurately predict fracture risk. The study will provide novel information about possible clinical utility of minimally invasive, in vivo bone indentation measurements to measure bone strength and its relationship to fracture risk.
Aim 3: An amendment to the protocol expanded the study population to now include males >50 years who present with distal radius fractures and those who present for a reason other than fracture (non-fracture controls). Hypotheses: Men >50 years with distal radius fractures will have worse bone tissue material properties compared to non-fracture controls even after adjustment for BMD and other potential confounders.

We will use the handheld Osteoprobe device to measure cortical bone reference point indentation properties.
Device: Reference Point Indentation
We will recruit males to this second study arm, to use the handheld Osteoprobe device to measure cortical bone reference point indentation properties.
Device: Reference Point Indentation
The "Osteoprobe": Since these first reports of indentation measurements in humans in vivo, a more 'user-friendly' device, the Osteoprobe® has been developed by Active Life Scientific (Santa Barbara, CA) (10). The Osteoprobe®, which we will use in the current study, is smaller than the previous reference point indentation (RPI) instrument and is designed to be used in a hand-held fashion to allow for rapid measurements. The new instrument does not require a reference probe, because the inertia of the instrument keeps it adequately fixed in space during the short time of the indentation impact (\~0.25 milliseconds). The main parameter measured is the distance that the probe further indents into the bone from the reference point. Key components of the Osteoprobe® include an impact generation mechanism, a displacement transducer, and a probe made of hardened stainless steel with a 90 degree conical tip, with a tip diameter of \~375 µm.
