The goal of this study was to compare the biomechanical stability of cannulated locking screws and noncannulated cortical locking screws in a periarticular locking plate. Twelve fresh-frozen porcine tibias with a 1-cm gap created distal to the tibial plateau were used to simulate an unstable proximal tibial fracture. All specimens were fixed with a periarticular proximal lateral tibial locking ...

The Material Point Method is a relative newcomer to the world of solid mechanics modelling. Its key advantage ability model problems having large deformations while being relatively close standard finite element methods, however its use for realistic engineering applications will happen only if material point can be shown both efficient and accurate (compared methods), when modelling complex ge...

Anatomically precontoured locking plates are intended to facilitate the fixation of articular fractures and particularly those associated with osteoporosis. Fractures of the distal humerus are relatively uncommon injuries where operative intervention can be exceptionally challenging. The distal humeral trochlea provides a very narrow anatomical window through which to pass a fixed-angle locking...

Aim: Outcome of precontoured locking plates fixation in Distal Humerus Fractures. Material and methods: Twenty-five patients with distal humerus fractures were treated with ORIF with pre-contoured locking plates. There were 16 males, 9 females, with an average age of 42.8 years (2159years). As per the AO classification performance score, the results obtained were graded as excellent or good res...

The study included 51 patients with tibia fractures, who underwent percutaneous bone reposition and stabilization with unrimed tibial locking nail. The results obtained using this method were compared with those obtained by standard fracture treatment where flat and anatomic plates were applied (n = 64). In patients who had osteosynthetic material implanted percutaneously (using unrimed tibial ...

This paper investigates the capacity of solid finite elements with independent interpolations for displacements and strains to address shear, membrane volumetric locking in analysis beam, plate shell structures. The performance proposed strain/displacement formulation is compared standard one through a set eleven benchmark problems. In addition relative both element formulations, studies effect...

The goal of this study was to determine whether there is any biomechanical difference in terms of construct strength with axial loading between volar fixed-angle locking plates with threaded locking vs smooth locking pegs. The control group comprised 7 cadaveric specimens with threaded locking pegs, and the test group comprised 7 cadaveric specimens from the same donor with smooth locking pegs....

While the dominant approach to persistent storage in practice is to use a relational DBMS, there are some specialist applications that rely on object stores. The performance of these applications depends heavily on the efficiency of the object store’s concurrency control mechanism. Today’s predominant concurrency control mechanism is strict two-phase object locking. In the 80s, an interesting a...

STATEMENT OF PROBLEM Unlike screw-retention type, fixture-abutment retention in Locking taper connection depends on frictional force so it has possibility of abutment to sink. PURPOSE In this study, Bicon® Implant System, one of the conical internal connection implant system, was used with applying loading force to the abutments connected to the fixture. Then the amount of sinking was measure...
