13. ROTATION ASSESSMENT IN ADOLESCENT IDIOPATHIC SCOLIOSIS WITH ROD DEROTATION
RESUMO Objetivo: A escoliose idiopática do adolescente é caracterizada por deformidade rotacional e lateral da coluna vertebral. A medição da rotação vertebral é importante para o prognóstico e tratamento. Nosso objetivo foi avaliar se o método de Nash-Moe pode ser usado para medir a correção da deformidade axial com o tratamento cirúrgico usand

14. Método não ionizante de rastreamento da escoliose idiopática do adolescente em escolares
Resumo Escoliose idiopática do adolescente (EIA) atinge de 2% a 4% de jovens no Brasil. Repetidas exposições aos exames radiológicos, no acompanhamento desta deformidade, podem ser danosos à saúde. O objetivo deste estudo é apresentar um protocolo de fotogrametria, como método não ionizante para quantificação da escoliose, e relacioná-lo ao méto

15. External morphology, postcranial and appendicular osteology of three southwestern Atlantic flatfishes ( Paralichthys , Paralichthyidae), and comparisons with other congeneric species
ABSTRACT Comparisons of the external morphology and analysis of osteological features of the postcranial and appendicular skeletons of three southwestern Atlantic flatfish species of the genus Paralichthys (P. isosceles, P. orbignyanus and P. patagonicus) were carried out. Bones are described, and detailed morphological, morphometric and meristic characteris

16. Evaluation of an inexpensive needle test for the diagnosis of phosphorus deficiency and management of phosphorus supplementation for cattle: A multiple case study
ABSTRACT The needle test (NT) is a point-of-care test developed in Brazil to evaluate the Phosphorus (P) status in cattle. Based on bone resistance, the NT is a very inexpensive method which allows the diagnosis of any degree of P deficiency in a fast and simple way in vivo and directly on farm. The NT measures three levels of resistance in the transverse pr

17. A giant on the ground: another large-bodied Atractus (Serpentes: Dipsadinae) from Ecuadorian Andes, with comments on the dietary specializations of the goo-eaters snakes
ABSTRACT Body-size is significantly correlated with the number of vertebrae (pleomerism) in multiple vertebrate lineages, indicating that somitogenesis process is an important factor dictating evolutionary change associated to phyletic allometry and, consequently, species fitness and diversification. However, the role of the evolution of extreme body sizes (

18. Morphology of the Diaphragm Muscle in Southern Tamandua (Tamandua tetradactyla) and its Importance in Cases of Traumatic Hernia
ABSTRACT The wall of the diaphragm can be affected by changes caused by physical trauma, allowing the passage of viscera between the abdominal cavity and thoracic cavity, thus reducing the space for pulmonary expansion, leading to the formation of hernia and possible death. Thus, we aimed to characterize, size and determine the topography of the diaphragmati

19. Clinical and radiographic outcomes of upper thoracic versus lower thoracic upper instrumented vertebrae for adult scoliosis: a meta-analysis
The aim of this study was to evaluate the clinical and radiographic outcomes of upper thoracic (UT) versus lower thoracic (LT) upper instrumented vertebrae (UIV) for adult scoliosis by meta-analysis. We conducted a literature search in three databases to retrieve related studies up to March 15, 2017. The preliminary screened studies were assessed by two revi

20. Compressão de medula espinhal ocasionada por melanoma em cavalo de pelagem castanha
ABSTRACT This paper describes a case of malignant melanoma in brown coat horse, which had ataxia and proprioceptive deficits in hind limbs, progressing to permanent decubitus. The animal was euthanized and the final diagnosis was based on necropsy and histopathology. At necropsy different masses and / or nodules in skeletal muscle, bone, abdominal cavity, lu

21. Comparison of short-segment monoaxial and polyaxial pedicle screw fixation combined with intermediate screws in traumatic thoracolumbar fractures: a finite element study and clinical radiographic review
OBJECTIVES: No studies have compared monoaxial and polyaxial pedicle screws with regard to the von Mises stress of the instrumentation, intradiscal pressures of the adjacent segment and adjacent segment degeneration. METHODS: Short-segment monoaxial/polyaxial pedicle screw fixation techniques were compared using finite element methods, and the redistribute

22. X-ray dynamic observation of cervical degenerative disease induced by unbalanced dynamic and static forces in rats
Abstract Purpose: To investigate dynamically the X-ray appearance of cervical degenerative disease induced by unbalanced dynamic and static forces in rats. Methods: A total of 60 Sprague Dawley rats were randomized into test (n=45) and control (n=15) groups, which were randomly subdivided into the one-, three- and six-month post-operative groups. The tes

23. Axial compressive strength of human vertebrae trabecular bones classified as normal, osteopenic and osteoporotic by quantitative ultrasonometry of calcaneus
Abstract Introduction Biomechanical assessment of trabecular bone microarchitecture contributes to the evaluation of fractures risk associated with osteoporosis and plays a crucial role in planning preventive strategies. One of the most widely clinical technics used for osteoporosis diagnosis by health professionals is bone dual-energy X-ray absorptiometry

24. Efficacy of Carbon Microcoils in Relieving Cervicogenic Dizziness
Abstract Introduction Cervical pain contributes to postural deviations and imbalance. Nanotechnology may be used for the treatment of neck pain by fixing to the skin small rounds silicone patches containing double spiral carbon nanotubes arranged in the form of a coil (Helical), which would then relieve dizziness caused by muscular contraction.
