Femur properties of embryo in the layer hybrid and pure breeds
(Fundacao APINCO de Ciencia e Tecnologia Avicolas, 2018-10-01)
Layer hybrids are more superior in the egg yield than pure breeds. But this superiority causes some problems in the bones during the production period. There are a lot of differences among genotypes in the production period ...
Biomechanical comparison of transdiscal fixation and posterior fixation with and without transforaminal lumbar interbody fusion in the treatment of L5–S1 lumbosacral joint
(SAGE Publications Ltd, 2018-04-01)
Transdiscal screw fixation is generally performed in the treatment of high-grade L5–S1 spondylolisthesis. The main thought of the study is that the biomechanical performances of the transdiscal pedicle screw fixation can ...
Methyl methacrylate in external fixation of supracondylar humerus fractures: An experimental study
(2018-10-01)
Supracondylar humerus fractures are common fractures around the elbow. Open fractures, comminuted metaphyseal fractures and also fractures with bone loss may need to be treated with external fixators. The aim of this study ...
The use of a proximal femoral nail as a hip prosthesis: A biomechanical analysis of a newly designed implant
(SAGE Publications Ltd, 2018-02-01)
Complication rates of hip fractures after proximal femoral nail are not rare. In such fractures, treatment invariably comprises the extraction of proximal femoral nail and the introduction of a different hip prosthesis. ...
Biomechanical comparison of three different fixation techniques for anterior column posterior hemitransverse acetabular fractures using anterior intrapelvic approach
(Elsevier Ltd, 2018-08-08)
Objectives: The aim of this study was to biomechanically compare three different fixation methods for the fixation of anterior column posterior hemitransverse type acetabular fracture (ACPHT). Methods: ACPHT fracture models ...
Do we need a transforaminal lumbar interbody fusion cage to increase the stability of functional spinal unit when comparing unilateral and bilateral fixation?
(SAGE Publications Ltd, 2018-07-01)
Transforaminal lumbar interbody fusion was an alternative to posterior lumbar interbody fusion for decompression surgeries. This study investigates the biomechanical responses of the unilateral and bilateral pedicle screw ...
Comparison of rigid and semi-rigid instrumentation under acute load on vertebrae treated with posterior lumbar interbody fusion/transforaminal lumbar interbody fusion procedures: An experimental study
(SAGE Publications Ltd, 2018-04-01)
Rigid and semi-rigid fixations are investigated several times in order to compare their biomechanical stability. Interbody fusion techniques are also preferable for maintaining the sagittal balance by protecting the disk ...
Investigation of toggling effect on pullout performance of pedicle screws
(SAGE Publications Ltd, 2018-04-01)
Objective of this study is to assess the pullout performance of various pedicle screws in different test materials after toggling tests comparatively. Solid core, cannulated (cemented), novel expandable and solid-core ...
Perforated H-beam implant can be used in femoral neck fracture
(SAGE Publications Ltd, 2019-03)
This biomechanical study evaluated comparison osteosynthesis of the femoral neck fracture model by 3 cannulated screw implants and new perforated H beam implants under different loading conditions with 45 third generation ...
Precontoured buttress plate vs reconstruction plate for acetabulum posterior wall fractures: A biomechanical study
( Baishideng Publishing Group Co, 2019-05)
Background: The purpose of open reduction and internal fixation of acetabulum posterior wall fractures is to restore anatomical structure and stability of the hip joint, in order to start weight bearing as soon as possible ...
