Injectable calcium phosphate cement for augmentation around cancellous bone screws. In vivo biomechanical studies

In lower cancellous apparent bone density, it can be difficult to achieve adequate screw fixation and hence stable fracture fixation. Different strategies have been proposed, one of them is through augmentation using calcium phosphate cement in the region ...

Combined effects of zoledronate and mechanical stimulation on bone adaptation in an axially loaded mouse tibia

Dominique Pioletti, Vincent Stadelmann

Background: Local bisphosphonate delivery may be a solution to prevent periprosthetic bone loss and improve orthopedic implants fixation. In load-bearing implants, periprosthetic bone is exposed to high mechanical demands, which in normal conditions induce ...

Calcium phosphate cement augmentation of cancellous bone screws can compensate for the absence of cortical fixation

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann

An obvious means to improve the fixation of a cancellous bone screw is to augment the surrounding bone with cement. Previous studies have shown that bone augmentation with Calcium Phosphate (CaP) cement significantly improves screw fixation. Nevertheless, ...

Prediction of bone density around orthopedic implants delivering bisphosphonate

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann

The fixation of an orthopedic implant depends strongly upon its initial stability. Peri-implant bone may resorb shortly after the surgery. This resorbtion is directly followed by new bone formation and implants fixation strengthening, the so-called seconda ...

The Matricellular Protein Periostin Is Required for Sost Inhibition and the Anabolic Response to Mechanical Loading and Physical Activity

Vincent Stadelmann

Periostin (gene Postn) is a secreted extracellular matrix protein involved in cell recruitment and adhesion and plays an important role in odontogenesis. In bone, periostin is preferentially expressed in the periosteum, but its functional significance rema ...

Osteoclastogenesis can be mechanically-induced in the peri-implant bone

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann

Total joint replacements are highly successful in relieving pain and restoring movement of damaged joints. However, the lifespan of the implants is limited. The implant’s long-term stability depends largely on the preservation of periprosthetic bone. Debri ...

3D strain map of axially loaded mouse tibia: a numerical analysis validated by experimental measurements

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann, Francesco Merlini, Vincent Forster, Jean Hocké

A combined experimental/numerical study was performed to calculate the zone of highest strain in a rat tibia loaded axially. This study is motivated by the fact that the bone remodeling analysis in this in vivo rat model should be performed at the zone of ...

3D strain map of axially loaded mouse tibia: a numerical analysis validated by experimental measurements

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann, Francesco Merlini, Vincent Forster, Jean Hocké, Jensen Verhelle

A combined experimental/numerical study was performed to calculate the 3D octahedral shear strain map in a mouse tibia loaded axially. This study is motivated by the fact that the bone remodelling analysis, in this in vivo mouse model should be performed a ...

Prevention of micromotion-related periprosthetic bone loss using local release of bisphosphonate : theoretical developments and experimental validations

Vincent Stadelmann

Total joint replacements are highly successful in relieving pain and restoring movement of damaged joints. However, the lifespan of the implants is limited. The implant's long-term stability depends largely on the preservation of periprosthetic bone. Debri ...
