Four corner arthrodesis is an accepted salvage operation for scapholunate advanced collapse and scaphoid non-union advanced collapse. Circular plates were introduced in 1999 and promoted as a rapid and more stable method for this procedure. A retrospective chart review was performed on all patients who were treated with the Spider Limited Wrist Fusion Plate (Kinetikos Medical Inc., San Diego, C...

The mathematical modeling and finite element analysis of solid circular plates, analyzed using continuum elements under conditions axisymmetry, is investigated in this paper. Both isotropic anisotropic material characterizations are considered. Once a suitable “baseline” model developed, parametric analyses performed so as to gain insight into the behavior plates.

This study is the first report of numerical solution of nonlinear bending analysis for annular and circular plates based on 3D elasticity theory with asymmetric boundary conditions using semi-analytical polynomial method (SAPM). Orthotropic annular and circular plates are subjected to transverse loading and 3D bending analysis in the presence of symmetric and asymmetric boundary conditions is s...

We studied the polarized light patterns obtained using a thin film of ferrofluid subjected to an applied magnetic field. with field configurations between parallel plates, monopolar, tetrapolar, and hexapolar, how varies for different intensities orientations Using Jones calculus, we explored key optical properties this system these relate have observed general aspects by transmission in Ferroc...
