Association of a Polygenic Risk Score With Osteoporosis in People Living With HIV: The Swiss HIV Cohort Study

Jacques Fellay, Christian Axel Wandall Thorball

An individual polygenic risk score was associated with osteoporosis in people living with HIV. The genetic effect was robust, as it persisted after multivariable adjustment for established traditional and HIV-related osteoporosis risk factors, including te ...

Age- and sex-specific normative values of bone mineral density in the adult glenoid

Dominique Pioletti, Alexandre Terrier, Alain Farron, Patrick Goetti, Frédéric Vauclair, Philippe Büchler

The objective of this study was to determine the normative bone mineral density (BMD) of cortical and trabecular bone regions in the adult glenoid and its dependence on the subject's age and sex. We analyzed computed tomography (CT) scans of 441 shoulders ...

Microtensile failure mechanisms in lamellar bone: Influence of fibrillar orientation, specimen size and hydration

Johann Michler, Daniele Casari, Tatiana Kochetkova

A mechanistic understanding of bone fracture is indispensable for developing improved fracture risk assessment in clinics. Since bone is a hierarchically structured material, gaining such knowledge requires analysis at multiple length scales. Here, the ten ...

Estimating People Flows to Better Count Them in Crowded Scenes

Pascal Fua, Mathieu Salzmann, Weizhe Liu

Modern methods for counting people in crowded scenes rely on deep networks to estimate people densities in individual images. As such, only very few take advantage of temporal consistency in video sequences, and those that do only impose weak smoothness co ...

Patellar bone strain after total knee arthroplasty is correlated with bone mineral density and body mass index

Dominique Pioletti, Alexandre Terrier, Adeliya Latypova, Elham Taghizadeh, Philippe Büchler

Patella-related complications after total knee arthroplasty (TKA) remain a major clinical concern. Previous studies have suggested that increased postoperative patellar bone strain could be related to such complications, but there is limited knowledge on p ...

Non-setting, injectable biomaterials containing particulate hydroxyapatite can increase primary stability of bone screws in cancellous bone

Dominique Pioletti, Ulrike Kettenberger, Jorge Solana Munoz

BACKGROUND: Fracture fixation in weak bone is still a clinical challenge. Screw augmentation was shown to successfully increase their primary stability. The currently used calcium phosphate or polymeric bone cements, however, present important drawbacks su ...

Fatigue as the missing link between bone fragility and fracture

Dominique Pioletti, Vincent Stadelmann, Claire Acevedo

The prevention of fragility fractures in bone—pathologic fractures resulting from daily activity and mostly occurring in the elderly population—has been a long-term clinical quest. Recent research indicating that falls in the elderly might be the conse- qu ...

Peri-implant bone adaptations to overloading in rat tibiae: experimental investigations and numerical predictions

John Botsis, Joël Cugnoni, Marco Piccinini

Objectives(i) To assess the effects of mechanical overloading on implant integration in rat tibiae, and (ii) to numerically predict peri-implant bone adaptation. Materials and methodsTranscutaneous titanium implants were simultaneously placed into both tib ...

Biomechanical Role of Bone Anisotropy Estimated on Clinical CT Scans by Image Registration

Alexandre Terrier, Adeliya Latypova, Elham Taghizadeh, Philippe Büchler

Image-based modeling is a popular approach to perform patient-specific biomechanical simulations. Accurate modeling is critical for orthopedic application to evaluate implant design and surgical planning. It has been shown that bone strength can be estimat ...
