Scanning and transmission electron microscopy for evaluation of order/disorder in bone structure

A comparative characterization of the structure of normal and abnormal (osteoporotic) human lumbar and thoracic vertebrae samples was carried out to reveal the type of possible disorder. Samples from the bone fragments extracted during the surgery due to v ...

Hierarchical interconnections in the nano-composite material bone: Fibrillar cross-links resist fracture on several length scales

Georg Fantner

Bone is a complex and very important multi-constituent bio-composite. In this work, we focus on the arrangement of bone constituents from the nanoscopic to the microscopic scale, and investigate the influence of their arrangements on the fracture mechanism ...

Novel techniques for high-resolution functional imaging of teabecular bone

Georg Fantner, Randoald Müller

In current biological and biomedical research, quantitative endpoints have become an important factor of success. Classically, such endpoints were investigated with 2D imaging, which is usually destructive and the 3D character of tissue gets lost. 3D imagi ...

Peri-implant bone remodeling after total hip replacement combined with systemic alendronate treatment: a finite element analysis

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo, Bastian Peter

In order to decrease the peri-implant bone loss during the life-time of the implant, oral use of anti-osteoporosis drugs (like bisphosphonates) has been suggested. In this study, bone remodeling parameters identified from clinical trials of alendronate wer ...

Can the increase of bone mineral density following bisphosphonates treatments be explained by biomechanical considerations?

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo

OBJECTIVE: We hypothesized that bone mineral density increase following bisphosphonates treatments may be explained by the influence of the drug on the mechanical bone remodeling parameters. BACKGROUND: Patients treated with bisphosphonates continuously in ...

Injectable calcium phosphate hydraulic cement (CPHC) used for periodontal tissue regeneration: A study of a dog model

Jacques Lemaître, Pascale Van Landuyt

Injectable calcium phosphate hydraulic cement (CPHC) is a new bone substitute family. This study aimed to evaluate the use of CPHC in surgical periodontitis-simulating defects in a dog model. CPHC was obtained by adding powder mixtures of different calcium ...

Acrylic acid grafting and collagen immobilization on poly(ethylene terephthalate) surfaces for adherence and growth of human bladder smooth muscle cells

Florian Maria Wurm, Peter Frey

In tissue engineering, degradable or non-degradable polymer matrices can act as cell-carrier-scaffolds. Cell adhesion and growth on these scaffolds can be promoted by immobilizing extracellular matrix proteins. Therefore, in this study, polymer poly(ethyle ...

Implants osseux

Jacques Lemaître

NOVELTY - The bone substitute is made in one piece from cement phosphocalcium materials consolidated chemically at low temperature and in presence of water. USE - In medicine, as artificial bone graft. ADVANTAGE - Macroporous structure promotes resorption ...

A constitutive law for trabecular bone

Motivated by applications in orthopaedic surgery, new constitutive laws for trabecular (or spongious) bone are developed in the framework of continuum mechanics, implemented in a mechanical analysis computer program, validated by a number of in vitro exper ...
