In vitro measurement of bone-implant micromotion of tibial implants after total ankle replacement

Background: Total Ankle Replacement (TAR) o_ers the advantage of preserving ankle joint motion compared with ankle arthrodesis. However, compared to hip or knee arthroplasty, TAR is a less successful procedure when considering the relatively low implants s ...

Theoretical Study for Safe and Efficient Energy Transfer to Deeply Implanted Devices Using Ultrasound

Catherine Dehollain

The goal of this paper is to prove that a safe and efficient energy transfer is possible between an external transducer located on the patient's skin and a device deeply implanted in the abdomen. An ultrasound propagation model based on the Rayleigh-Sommer ...

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

Dominique Pioletti, Vincent Stadelmann

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 ...

Osteoconductive surfaces generated from peptide functionalized poly(2-hydroxyethyl methacrylate-co-2-(methacryloyloxy)ethyl phosphate) brushes

Harm-Anton Klok, Dusko Paripovic

Modification of bone implant materials with biofunctional surfaces that facilitate osteoblast adhesion and promote matrix mineralization is an attractive strategy to improve osseointegration. This manuscript discusses the preparation and properties of RGD ...

Simultaneous and multisite measure of micromotion, subsidence and gap to evaluate femoral stem stability

Dominique Pioletti, Alexandre Terrier, Miguel Gortchacow

The initial stability of cementless femoral components is crucial for the long-term success of total hip arthroplasty. This has been reported in animal and clinical studies. Until now, the stability was evaluated by the measurement of relative micromotion ...

Improving Control of Dexterous Hand Prostheses Using Adaptive Learning

Barbara Caputo, Tatiana Tommasi

At the time of writing, highly dexterous hand prostheses are being manufactured and, to some extent, marketed. This means wearable, implantable mechanical hands with many independently controllable degrees of freedom, e.g. finger flexion and thumb rotation ...

Postoperative scapula fracture after reversed shoulder arthroplasty

Julien Ston

Reversed shoulder arthroplasty (RSA) is recommended in case of severe muscle deficiency, along with important joint wear. Although having a correct placement of the prosthesis after the operation and a recovery of the mobility, several cases of scapula fra ...
