The aim of this study was to compare the biomechanical properties of medial and lateral plating of a medially comminuted supracondylar femoral fracture. A supracondylar femoral fracture model comparing two fixation methods was tested cyclically in axial loading. One-centimetre supracondylar gap osteotomies were created in six synthetic femurs approximately 6 cm proximal to the knee joint. There...

The problems of lateral displacement control and usability of a structure are treated as the main part in high-rise buildings. Lateral displacement and usability control can be effectively managed through stiffness design. In this paper the non-dominated sorted genetic algorithm, NSGA-II, which may be used to satisfy many objective functions is applied to the structural design of high-rise buil...

Objective: Lateral humeral condyle fractures are troublesome injuries and are common among the lower end humerus epiphyseal injuries. These fractures are prone to go for non union . Preference for treatment of these nonunions, is to be individualised. Methods, varying from open reduction internal fixation with or without bone pegs, varus osteotomy to displacement osteotomy in gross valgus defor...

MRI cardiac tagging has been established as the gold standard in assessing intramyocardial displacement and strain. Yet, despite the high imaging quality of cardiac MRI, tagging techniques are limited by low spatial and temporal resolution. It has been recently shown that axial displacement and strain could be estimated and utilizing Bscan ultrasonography [1]. We compared and correlated intramy...

OBJECTIVES To determine if screw displacement axis patterns describing elbow joint motion: (1) change after ligament transection in vitro; (2) can reflect subtle changes in stability as a function of forearm position; (3) can reflect dynamic stabilization of the ligament insufficient elbow provided by muscle activity.Design. An in vitro kinematic study of eighteen cadaveric specimens tested in ...

Diffraction gratings have been proposed as core elements in future laserinterferometric gravitational-wave detectors. In this paper, we use a steady-state technique to derive coupling of lateral grating displacement to the output ports of a diffractive Fabry-Perot cavity. By introducing a signal to noise ratio (SNR) for each of the three cavity output ports the magnitude of the noise sidebands ...

Lumbar disc herniation arises when the annulus fibrosus of the vertebral disc fails, thus allowing displacement of the nucleus pulposus and other tissue. The term far lateral is used variably in the literature and usually refers to an extraforaminal displacement in the peridiscal zone peripheral to the sagittal plane of the most lateral part of the pedicle at the same level. Non-surgical treatm...

A new dynamic model is presented for piezoelectric tube actuators commonly used in high-precision instruments. The model captures coupling between motions in all three axes such as bending motion due to a supposedly pure extension of the actuator. Both hysteresis and creep phenomena are included in the overall actuator model permitting modeling nonlinear sensitivity in the voltage to displaceme...
