A rare catastrophic failure of modular component Total Hip Arthroplasty is dissociation between liner and cup, which has been associated with component malposition and/or impingement and seems to be more frequently associated with the Pinnacle system. The goal of this study was to evaluate the resistance of a polyethylene liner to lever-out-forces ...

The evolution in total knee arthroplasty (TKA) includes the highly cross-linked polyethylene (HXLPE) which has been reported as an effective manner to reduce the wear of the polyethylene and the osteolysis. The purpose of the present study is to synthesize the results of comparative studies between HXLPE and conventional polyethylenes and determine...

La réduction des nuisances sonores est un enjeu permanent pour les acteurs du transport aérien, notamment autour des aéroports. En particulier, le bruit de soufflante (fan noise) tient une place importante dans le bruit global de l’avion. Aussi, relativement à la réduction du bruit d’aéronef, sont développés des matériaux dits liners positionnés le...

Investigating the suitability of tropical clays for engineering applications is very essential due to daily encounter by practitioners as a result of ongoing massive engineering infrastructural constructions and the need for alternative and local materials that will ultimately reduce the overall project construction costs. Tropical clays from diffe...

ĂAircraft engines are one of the dominant noise sources for subsonic aircraft, resulting in a dense research field aimed at noise reduction inside the engine nacelle. In current turbofan engines, the inlet, bypass and exhaust parts of the nacelle are lined with acoustic liners. Liners consist essentially of a perforated plate backed by an air cavit...

The aim of this study was to evaluate the influence of a liner on the clinical performance of deep posterior restorations performed with bulk-fill composite. 30 subjects received two restorations on deep preparations in posterior teeth, without pulpal exposure, after selective carious-tissue removal in one-stage. The internal walls reached the inne...

Diurnal volume changes is one of the main factors influencing socket fit in transtibial prosthesis and causing pressure problem issues. Embedded bladder liners have been recently a potential approach to deal with this problem. The aim of this technical note was to introduce a new transtibial silicone liner designed based on hybrid socket theory. To...

Ilio-psoas impingement after total hip arthroplasty often occurs with the metallic rim of the acetabular cup. The main causes are poor cup anteversion or anterior wall defect. We firstly report here the case of a patient complaining of iliopsoas impingement due to contact with the liner of a dual-mobility device. Ultrasonography and Computed Tomogr...

Acoustic liners are specific devices dedicated to reduce noise pollution of aircraft. They contained a large number of cavities which are submitted to a turbulent grazing boundary flow. In some cases, the shear layer can become unstable, and couples with the acoustic waves propagating in the cavity, leading to a strong vortex-noise interaction. Whe...
