It has been suggested that the vibration transmission across a fracture is affected by the stages of healing of the fracture callus. This study aims to correlate the change in vibration transmission with mechanical stiffness of the callus measured by three-point bending. The right tibiae of male, three-month old local albino rabbits were osteotomized and stabilized by intramedullary fixation following open reduction. The intramedullary rods were removed on the 15th, 28th, 42nd and 90th days postoperatively and the tibiae were excised for vibration, three-point bending and bone mineral density analysis by quantitative computerized tomography (QCT). Optimum time for clinical weight bearing was determined by checking the convergence of the vibration parameters of the fractured tibia to those of the unfractured contralateral. The conclusions obtained from curvature analysis, based on vibration experiments, were in considerable correlation (Spearman's rank correlation coefficient r = 0.93, p = 0.003) with the conclusions obtained from the three-point bending test data which reflected the mechanical condition of the bone by direct means. However, no correlation between bone mineral density change and vibration transmission was noted.

Biomechanics of the Gazi type pelvis external skeletal fixator
Korkusuz, Feza; Kaymak, O; Citipitioglu, E; Akkas, N (1997-01-01)
External skeletal fixation is an alternative method of treatment to conventional therapy and open surgical procedures in pelvis fractures. The appropriate type of frame and the configuration of the connecting bars of these fixators are under investigation. In the Gazi type pelvis external fixator (GPEF) which has been developed, a 70 degrees angulation is applied to the connecting bars of the anterior quadrangular frame. This configuration, which is expected to improve the stability of the posterior column ...
Mechanical design and analysis of a novel fixation device for human bone fractures
Yenigün, Çağrı; Tönük, Ergin; Oğuz, Erbil; Department of Biomedical Engineering (2016)
Fixation of bone fractures over a desired time period is one of the most important requirement for their healing processes. Fracture fixation devices are designed to satisfy particular requirements for different types of bone fractures. Conventional and locking plates, intramedullary rods and screws of trauma surgery, and polyaxial screws, connectors and rods of spinal surgery are the examples of contemporary implants for varying bones and their fractures. The mentioned fixation system is inspired from spin...
Study on the influence of scaffold inner organization on the treatment of spinal cord injury
Dursun, Tuğba; Hasırcı, Deniz; Yücel, Deniz; Department of Biotechnology (2013)
Permanent loss of neurologic function occurs when the central nervous system (CNS) is injured. Nerve regeneration is extremely limited because of dense scar tissue formation at the lesion site, especially in the spinal cord. For the treatment of this type of injury, different strategies are needed. The emerging approach to solve these problems is to provide a physical support via tubular bridging devices such as “nerve guides”. They are used to bridge the neural gaps in the treatment of spinal cord injury, ...
Biodegradable polymer - hydroxyapatite nanocomposites for bone plate applıcations
Aydın, Erkin; Hasırcı, Vasıf Nejat; Planell, Joseph A.; Department of Biotechnology (2010)
Long bone fractures are fixed with bone plates to restrain movement of bone fragments. Fracture site must experience some pressure for proper healing. Bone plates are mostly made up of metals having 5 - 10 times higher elastic modulus than bones and most of the load is carried by them, leading to stress shielding and a bony tissue with low mineral density and strength. To avoid these problems, biodegradable polymer-based composite plates were designed and tested in this study. Poly(L-lactide) and Poly(3-hyd...
Design and Development of a Low Cost Device for Bone Fracture Detection Using FFT Technique on MATLAB
Qadir, Zakria; Ali, Muhammad; Nesimoglu, Tayfun (2018-11-02)
Bone fracture is a common problem in daily life which occurs when high pressure is applied on bone or by simple accident and also due to osteoporosis and bone cancer. Different techniques are used today to detect bone fractures such as X-Ray, Computed Tomography (CT-scan), Magnetic Resonance Imaging (MRI) and Ultrasound. Among these four modalities, X-ray diagnosis is commonly used for fracture detection. However, if the fracture is complicated, a CT scan or MRI may be needed for further diagnosis and opera...
