1. Cadaveric study of anatomical measurement of isthmus parameters of lumbar spine to guide cortical bone screw placement
SUMMARY OBJECTIVE: To reduce surgical exposure and improve accuracy, this study evaluated the anatomical distance parameter D (including D1, D2, and D3) of the lumbar isthmus for cortical bone screw insertion. METHODS: A total of 25 structurally complete lumbar dry specimens were used for lumbar anatomy measurements. The six cadaver specimens were divided

2. The influence of sex and level of physical activity on maximum tolerance to mechanical pain
Abstract Background A difference in maximum tolerance to mechanical pain (MTMP) between the sexes is widely studied but there is still no consensus on whether the level of physical activity (PA) influences pain. Objectives To compare the MTMP between men and women with different levels of PA. Methods Sixty five individuals were divided in female (n = 35)

5. A biomechanical study on proximal junctional kyphosis following long-segment posterior spinal fusion
Posterior long-segment spinal fusion may lead to proximal junctional kyphosis (PJK). The present study sought to identify the appropriate fusion levels required in order to prevent PJK using finite element analysis. A finite element model was constructed based on the whole-spine computed tomography findings of a healthy adult. Nine commonly used posterior sp

6. 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

7. 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

8. 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

9. 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

11. Estenose do canal lombar : relação do equilíbrio sagital com a avaliação clínica = Lumbar canal stenosis: relationship with the sagittal balance and the clinical evaluation / Lumbar canal stenosis : relationship with the sagittal balance and the clinical evaluation
There is a great variation in the results of previous studies analyzing sagital alignment parameters (SAP) in normal individuals and in patients with degenerative diseases of the lumbar spine. Most studies associate SAP only with chronic lumbar pain, in groups of patients with different lumbar degenerative diseases, which makes it difficult to apply these da

12. Efeito do fluoreto no osso de camundongos com diferentes susceptibilidades genéticas à fluorose: uma análise proteômica / Effect of fluoride on bone of mice with different genetic susceptibilities to fluorosis: a proteomic analysis
Genetic factors have been shown to influence bone and enamel responses to fluoride (F), but the molecular mechanisms involved remain unclear. In this study, a label-free proteomics approach was employed to identify and evaluate changes in bone protein expression of two mouse strains with different susceptibilities to fluorosis (A/J a susceptible strain, 129P
