BACKGROUND The symmetrical Lyon brace is a brace, usually used to maintain correction after a plaster cast reduction in the Cotrel's EDF (Elongation-Derotation-Flexion) frame. The new Lyon brace or ARTbrace is an immediate corrective brace based on some of the principles of the plaster cast which are improved due to advances in CAD/CAM technology. The aim of this paper is to describe concepts o...

necessitates immobihisation in a plaster spica for several weeks. In order to avoid this, and to allow early activity, various forms of internal fixation have been used. Most of these consist of some form of modified “ blade plate “ which is screwed to the femoral shaft. They all have disadvantages. The length and the extent of the operation are increased, and fixing the plate to the femur tend...

BACKGROUND Femoral fractures are common in children aged between 2 and 12 yearsand 75% of the lesions affect the femoral shaft. Traction followed by a plaster cast is universally accepted as a conservative treatment. We compared primary hip spica or traction followed by hip spica with closed reduction and fixation with retrogradely passed crossed Rush pins for diaphyseal femur fracture in 25 ch...

Abstract This paper discusses the scarce, but crucial evidence for plaster reliefs in Constantinople between ninth and thirteenth centuries. While many survived Balkan peninsula, there is room to confirm that they were also used capital. Plaster a quick substitution marble, could answer aesthetic needs architectural conventions continued from Late Antiquity Middle Byzantine architecture, even w...

One-hundred percent local plaster-based building materials were developed using Alfa (Stipa tenacissima L.) fibers from eastern Morocco region. Indeed, the incorporation of natural in is one promising approaches to design new bio-based and green sector. The present study concerns fabrication, investigation thermophysical properties energy saving potential Alfa-plasterboard for roofing applicati...

Objective : We report here results obtained concerning the authenticity of Napoléon’s RUSI death mask Napoléon. Methods mtDNA analyses three hairs included in plaster inter eyebrowed region mask, and SEM-EDX plaster, pencil lead used for inscription are realized. Results is “plâtre de Paris” soft graphite. The studied showed presence 16184T mutation ; that confirms an authentic replicate original
