BACKGROUND High tibial osteotomy is a common procedure to treat symptomatic osteoarthritis of the medial compartment of the knee with varus alignment. This is achieved by overcorrecting the varus alignment to 2-6° of valgus. Various high tibial osteotomy techniques are currently used to this end. Common procedures are medial opening wedge and lateral closing wedge tibial osteotomies. The latera...

To determine if changes in pulmonary capillary wedge pressure could be determined from the pulmonary blood volume (PBV) ratio response on exercise-gated blood pool images, 42 patients had simultaneous exercise-gated blood pool imaging and hemodynamic monitoring during cardiac catheterization. Nine patients were normal and 33 patients had cardiac disease. Changes in the PBV ratio were determined...

A prospective, randomised, controlled trial compared two different techniques of high tibial osteotomy with a lateral closing wedge or a medial opening wedge, stabilised by a Puddu plate. The clinical outcome and radiological results were examined at one year. The primary outcome measure was the achievement of an overcorrection of valgus of 4 degrees . Secondary outcome measures were the severi...

BACKGROUND Previous reviews have focussed on the rationale for employing the stepped wedge design (SWD), the areas of research to which the design has been applied and the general characteristics of the design. However these did not focus on the statistical methods nor addressed the appropriateness of sample size methods used.This was a review of the literature of the statistical methodology us...

Exact inviscid theory is applied to a simple lifting configuration consisting of a wedge beneath a plane wing, both the wedge and the wing being terminated by a trailing edge which lies along a Mach cone. The efficiency of such an arrangement is compared with the efficiency of a wedge producing lift directly through incidence, as in the Nonweiler wing. The comparison is favourable to the interf...

Mount St Helens is the most active volcano within the Cascade arc; however, its location is unusual because it lies 50 km west of the main axis of arc volcanism. Subduction zone thermal models indicate that the down-going slab is decoupled from the overriding mantle wedge beneath the forearc, resulting in a cold mantle wedge that is unlikely to generate melt. Consequently, the forearc location ...

in this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twome...

The specific aim of this study was to quantify muscle activity while performing squat with technique variations. Eight healthy volunteers performed squats under 5 types of foot positions: neutral position, under a 10o descending wedge, under a 10o ascending wedge, under a 10o medial wedge and under a 10o lateral wedge. It was evaluated electromyographic data of vastus medialis oblique, vastus l...
