PURPOSE The purpose of this study was to conduct a prospective outcome analysis of proximal tibial opening wedge osteotomies performed in young and middle-aged patients (aged <55 years) for the treatment of symptomatic medial compartment osteoarthritis of the knee. METHODS A consecutive series of young and middle-aged adults who underwent proximal tibial opening wedge osteotomies for symptoma...

BACKGROUND According to the literature, closing and opening wedge high tibial valgus osteotomies can raise or lower the patella, and diffèrent methods of patella height measurement show similarly conflicting results. Clarification of this was thought to be important because there is much literature describing morbidity secondary to patella alta or patella infera (baja). Effects on tibial slope ...

background: due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. however, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. so, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s child...

introduction emerging hypotheses suggest a causal role for prenatal androgen exposure in some cases of autism spectrum disorders (asd). the ratios of the lengths of the bones of the 2nd to the 4th digits (2d:4d) are purported to be markers for prenatal androgen exposure and to be established early in gestation. ratio of second and fourth digits (2d:4d)  is usually used as a proxy for prenatal t...

it is well-known that the behavior of soil-structure systems can be well described using a limited number of non-dimensional parameters. this is the outcome of researches based on the premise that the foundation is bonded to the ground. here, it is shown the concept can be extended to systems with foundation uplift. a set of non-dimensional parameters are introduced which controls the main feat...
