Konsep Diagnosis Dan Penatalaksanaan Fraktur Osteoporosis Terkini, I Gusti Ngurah Wien Aryana, Febyan Febyan

Jurnal Penyakit Dalam Indonesia

Osteoporosis is a metabolic bone disease that is caused by a decreased amount of bone mass, and microarchitectural damage to bone tissue that affects the bone to break easily. Osteoporosis can be divided into primary and secondary etiologies. Vertebral, hip, distal radius, and proximal humerus are the most common predilection of fracture complication due to osteoporosis. The diagnosis of osteoporotic fractures is established based on the identification of risk factors, general clinical manifestations, specific manifestation from each fracture predilection, and advanced examinations, including radiology imaging and dual-energy x-ray absorptiometry. The purpose of osteoporotic fractures management in elderly is a stable …

Recurrent Patellar Fracture in a Healthy Collegiate Basketball Player: An Exploration Clinical Case Report

ABSTRACT

Purpose: Patellar fractures only account for approximately 1% of all skeletal injuries. Patellar fractures usually result from direct trauma (i.e. falling on the knee, dashboard injury, etc.), or, less frequently, occur as a combination of direct and indirect mechanism (i.e. receiving a direct blow while contracting the quadriceps). While indirect trauma is the least common mechanism, it usually occurs due to an extensor mechanism failure during eccentric loading such as landing. Method: Case report, Level 3: Exploration Clinical Contribution to the Available Sources of Evidence …

The Treatment Of Supracondylar And Diaphyseal Femoral Fractures Incats Using Intramedullary Two-Way Stacked Kirschner Wire Application, Kemal Altunatmaz, Murat Karabağli, Di̇dar Aydin, Özlem Güzel, Ebru Eravci Yalin, Ümi̇t Uğurlu, Defne Joan Şadalak, Hi̇mmet Eki̇ci̇

Turkish Journal of Veterinary & Animal Sciences

Femoral fractures in cats are treated using pin and wires, lag screws, Rush pins, intramedullary threaded pins, interlocking pins, clamp rod internal fixators, and plates or plate-rods. In this study, 14 cats brought to the surgery clinic between the years 2010 and 2015 for fracture, due to either a road traffic accident or falling from a height, were evaluated. Following clinical and radiological examination of the cases, the type and location of the fracture, details of the applied fixation method, and postoperative clinical and radiological results were assessed. Localization of the fractures was as follows: 4 comminuted diaphyseal (1 segmental), …

Regeneration And Healing Of Bone And Cartilage In Type-1 And Type-2 Diabetes: The Effects Of Insulin, Sümeyya Akyol, Mehmet Aki̇f Güleç, Hi̇lmi̇ Demi̇ri̇n, Ömer Akyol

Turkish Journal of Biology

Increased fragility of long bones and delay in fracture healing in adults as well as skeletal development disorders in children are thought to be associated with endochondral ossification problems. The extracellular matrix (ECM) of cartilage is absorbed during endochondral ossification. During the recovery process from damage, chondrocytes undergo hypertrophy and increase their cell volume; on the other hand, it is also necessary to digest the ECM elements around the cells. Recent research on the proteolytic enzymes in ECM assumed to be responsible for the digestion is connected to proteinases digesting type II collagen and aggrecan. ADAMTS1, 4, and 5 are …

The Treatment Of Distal Metacarpus Fracture With Locking Compression Plate In Calves*, Ali̇ Belge, İbrahi̇m Akin, Ali̇ Gülaydin, Muhammed Fati̇h Yazici

Turkish Journal of Veterinary & Animal Sciences

In this study, we aimed to evaluate the effect of locking compression plates for the treatment of distal metacarpal fractures in calves. The metacarpus was stabilized using a stainless steel locking compression plate with fully threaded locking head screws. The calves started weight-bearing partially after the first postoperative day and resumed complete weight-bearing after day 10. Callus formation was obtained at the end of the 3rd week and completed at the end of the 8th week, and complete healing was seen at the 12th week in radiographs. The limbs were in good alignment, the calves were fully weight-bearing, and client …

Fractures In Young, Single-Humped Camels (Camelus Dromedarius), Ahmed F. Ahmed, Fahd Abdullah Al-Sobayil

Turkish Journal of Veterinary & Animal Sciences

The objectives were to study the frequencies and classification of fractures in young camels and to evaluate the clinical relevance of external fixation as a method of treatment. Cases of fractures (n = 75) in young camels (less than 2 years old) were studied. On admission, the cause, site, classification, and radiography of the fractures as well as the methods of treatment were investigated. Factors affecting fracture healing after treatment were investigated and analyzed. The frequencies of fracture were affected by breed (P = 0.001) and age (P = 0.01) but not sex. Trauma was the most common cause of …

In this study, corpus mandibula fractures were experimentally induced on 30 rabbits and 3 different materials were used for fixation. Thirty rabbits were arranged into 3 groups and then wire, polydioxanone and mini plate and screw osteosynthesis materials were used. The fracture healing was examined and compared with clinical, radiological and histological results. From the radiological results the parameters of groups were compared with Lane and Sandhu scale system in terms of callus tissue, mineralization and remodeling. The histological results were evaluated according to the Modified Heiple scoring and compared for histological fracture healing and callus tissue. At the end …

Stress Corrosion And Stress Induced Surface Morphology Of Epitaxial Films, Michael Grinfeld

Scanning Microscopy

In addition to several new predictions, the general theory of thermodynamic stability of heterogeneous systems with rearrangement has allowed us to understand the roots of several experimental and theoretical results of the past. One of them is an outstanding paper of Asaro and Tiller on stress corrosion cracking by surface diffusion published two decades ago. We compare results of Asaro and Tiller with conclusions of thermodynamic theory of solids with rearrangement and develop some Asaro-Tiller results in the directions dictated by the needs of thin films technology and experiment. A surface diffusion model in a prestressed elastic solid is studied …

The Direct Sensing Of Damage To Ion Implanted Materials, J. S. C. Mckee, M. S. Mathur, G. R. Smith

Scanning Microscopy

Material damage caused by the implantation of a high concentration of hydrogenic ions requires regular remote monitoring in order to study the atomic and nuclear reaction processes taking place within each sample. Real time continuous measurements of acoustic emission, X-ray production and emitted particle flux enable processes such as bubble or crack formation, changes in crystalline order, and nuclear fusion reactions can be studied in detail through examination of secondary or associated emission products. Fracturing of a material may generate a unique signature which, when taken in conjunction with time-averaged quantities such as changes in resistivity, surface strain, and induced …

Processing Of Scanning Electron Microscope Images On Basis Of Fast Fourier-Transformation, A. Yu. Sasov, A. A. Shanyavsky

Scanning Microscopy

The solar cell as a combined substrate and detector was used for automated SEM-image analysis. It was noted that an image processing system was created and its operational features are shown in some typical applications. The step size of the fatigue striations was found. The obtained value of the step corresponds to the formula with an accuracy of about 1 per cent. Quantum-mechanical constant of material fracture for aluminum alloys was found to be 𝛥 = 0.22. Two-dimensional periodic analysis was applied to fracture surfaces and a microchannel plate. The integral characteristics of microstructure was determined quantitatively.

Scanning Electron Fractography Of Body Centered Cubic (Bcc) Metals, A. D. Vasilev

Scanning Electron Microscopy

Scanning electron fractography is an inherent part of investigations of factors which determine the mechanical properties of materials and their failure. Transition bcc metals show the widest variety of fracture mechanisms under uniaxial tension.

Brittle fracture is affected by cleavage from various defects - stress concentrators.

In brittle-ductile transition, fracture starts by a "tough" mode but finishes by a brittle one - by cleavage. A fracture mechanism changes after the "tough" crack has reached some critical length. Mechanisms of subcritical growth are of cleavage with relaxation, inter-granular fracture and dimpled ones.

Dimples are observed in ductile fracture. Cleavage is absent. …

Mechanical Properties Of Cheese, Cheese Analogues And Protein Gels In Relation To Composition And Microstructure, M. L. Green, K. R. Langley, R. J. Marshall, B. E. Brooker, A. Willis, J. F. V. Vincent

Food Structure

Samples of commercial Cheddar cheese, experimental Cheddar cheeses made from heated, ultrafiltration-concentrated mllks, processed cheese analogues and whey protein gels of defined composition were examined microscopically and some fracture and deformation properties were determined. Surfaces of cheese prepared by critical point drying and those examined frozen were comparable in microstructure. As the concentration factor of the milk used for experimental c heesemaking increased, the cheese became more resistant to reversible deformation, the work required to cut with a wire or break wf th a hammer increased and the microstructure showed that the protein matrix was coarser. The force to deform …
