OBJECTIVES The angled blade plate has been the historical standard in fixed-angle extramedullary subtrochanteric femur fracture fixation, but it requires an extensile lateral approach to the femur. Little formal evaluation exists for specifically designed percutaneous extramedullary implants. The purpose of this study was to compare 3 locked plating constructs, all with percutaneous insertion c...

Composite couple beams are the concrete elements consisting of longitudinal bars and steel plate, therefore suitable for shear transferring in couple shear walls with arranged gates in its height. In this paper, after modeling couple beams with and without steel plates with F.E methods and calibration the models with experimental results, effects of parameters such as thickness, height, length ...

Introduction: To determine the stiffness characteristics of a new proposed hybrid fixator in comparison with more commonly used commercialized hybrid external fixators and idealized hybrid fixator. Materials and Methods: A prospective laboratory investigation was used to test the mechanical stiffness between the new proposed hybrid fixator (Figure 1) and the more commonly used hybrid external f...

Bioresorbable plates have recently been used with anterior cervical discectomy and fusion (ACDF). Compared with metallic plates, bioresorbable plates provide segmental stabilization with minimal imaging artifact, eventual resorption, and increased load sharing. The objectives of the present study were to determine whether a bioresorbable plate can withstand simulated physiologic static and cycl...

Acoustic emission and transient IR thermography have been used to study and compare the performance of carbon/epoxy laminates, subjected to two different indentation procedures in a three-point flexural rig, one with a supporting steel plate and the other in a free bending mode. The study of 2-D localisation plots and cumulative counts vs. time curves allowed clarifying, with the essential supp...

The article considers the problem of a rectangular plate, supported by cross system stiffening ribs, bending. In addition to transverse load, plate is subjected forces in its plane, transmitted through ribs. Аn analytical solution boundary value for resolving differential equation with respect normal deflection describing deformation stiffeners, obtained. presented form series combinations regu...

OSTEOTRANS MX® (Takiron Co., Ltd., Osaka, Japan) is a bioactive resorbable maxillofacial osteosynthetic material composed of an unsintered hydroxyapatite/poly-l-lactide composite, and its effective osteoconductive capacity has been previously documented. However, the mechanical strength of this plate system is unclear. Thus, the aim of this in vitro study was to assess its tensile and shear str...

The aim of the study was to assess the influence of gap shape on biomechanical results in extra-articular distal humeral fracture: with contact on the posterior part (by anterior gap) and contact on ulnar column (by radial gap). The goal was to examine if and to what extent did displacements decrease in comparison with previously examined parallel gap without bony contact. The finite element an...
