Comparison of BMCs estimated using MRI and HR-pQCT.

, 2017
BMC based on MRI-derived total 31P content plotted against HR-pQCT derived BMC for a 1-cm thick slab of tissue for nine subjects (only nine of the subjects could be scanned because the scanner was unable to accommodate the limb size of one subject).

Accuracy and precision of internal displacement and strain measurements in long human bones using HR-pQCT and digital volume correlation

Computer Methods in Biomechanics and Biomedical Engineering: Imaging & Visualization
Digital volume correlation (DVC) is a technique for measuring 3D, internal displacements and strains in loaded structures. One application of DVC is the study of internal bone mechanics and the validation of subject-specific finite element (FE) models ...

Entropy, Assessed by Homeostatic Dysregulation on Electrocardiograms Predicts Fracture and Mortality

Aging Cell, Volume 24, Issue 12, December 2025.
Electrocardiogram‐based homeostatic dysregulation (ECG‐HD), a marker of cardiac conduction entropy, increases with age. Higher ECG‐HD is associated with a greater risk of aging outcomes including fractures and all‐cause mortality, independent of clinical risk factors, bone density, and ECG diagnoses.

Screening for Osteoporosis in Nonagenarians: A Scoping Review

Journal of the American Geriatrics Society, Volume 73, Issue 12, Page 3870-3883, December 2025.
ABSTRACT Background As the United States population continues to age and advancements contribute to enhanced life expectancy, care for nonagenarians (adults aged 90 years and older) is as important as ever. A prominent concern within healthcare for the oldest old remains the occurrence of fragility fractures, and subsequent 1‐year mortality, making ...

Surgical Treatment for Osteomalacia Induced by Causative Tumor in the Knee Joint Region: A Single‐Center Retrospective Clinical Study Over 10 Years

Orthopaedic Surgery, Volume 17, Issue 12, Page 3440-3455, December 2025.
The causative tumor for TIO in the knee joint region is hidden and has diverse locations, resulting in great challenges to endocrinologist and orthopedists. Due to the unique anatomical location and complex structure of the knee joint, orthopedic surgeons can adopt different surgical approaches to completely remove the causative tumor.

Robotic‐assisted burr preparation significantly improves cement penetration but not immediate fixation strength in total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 33, Issue 11, Page 3935-3943, November 2025.
Abstract Purpose Although robotic‐assisted total knee arthroplasty (TKA) is recognized for improving surgical precision, the effect of its bone preparation technique on cemented fixation remains unclear. This study compared the impact of robotic‐assisted burr versus oscillating saw techniques on cement penetration and fixation strength.

pQCT-assessed relationships between diaphyseal design and cortical bone mass and density in the tibiae of healthy sedentary and trained men and women

, 2013
In a pQCT study of running-trained and untrained men and women we had shown that bone mass distribution along the tibia was adapted to the usage-derived stress pattern.
