An important application of simulating wave propagation in bone is the early detection osteoporosis. During course this disease cortical reduced and replaced by marrow, weakening increasing likelihood fractures [1]. Commonly, modeling problem to only mechanical effects. Recent research includes electrical magnetic effects as well [2-4]. In our previous contributions we introduced a two-phase ma...

Osteointegration is a direct structural relationship between the bone and implant surface, properly osseointegration can function without mobility. We aim to evaluate this process using serial radiological examinations, where characteristics such as sclerosis cortical-periosteal thickening will be investigated. A retrospective analytic-observational study was conducted on 96 patients after ceme...

Osteitis fibrosa cystica is the classic patognomonic form of skeletal disease in hyperparathyroidism that characterizes with decreased cortical bone thickness compared to increased cancellous bone. We present a case of 52-year old female patient with osteolysis of the left calf on radiographic images. The bone scan detected multiple focal pathological accumulations in the skull, left tibia, bot...

Background and purpose: Auto-transplantation is the best bone graft substitute, but there are some limitations. Therefore, other methods using synthetic or natural materials are recommended. Propolis is a resinous natural product derived from plant exudates collected by honeybees. It has been extensively used in folk medicine because of its biological and pharmacological activities. The present...

In the attempt for using ultrasound as a diagnostic device for osteoporosis, several authors have described the result of the in vitro experiment in which ultrasound is passed through a cancellous bone specimen placed in a water tank. However, in the in vivo setting, a patient's cancellous bone is surrounded by cortical and muscle layers. This paper considers in the one-dimensional case (1) wha...

The mechanical properties of bone tissue are reflected in its micro- and nanostructure as well as in its composition. Numerous studies have compared the elastic mechanical properties of cortical and trabecular bone tissue and concluded that cortical bone tissue is stiffer than trabecular bone tissue. This study compared the progression of microdamage leading to fracture and the related local st...

We compared the bone healing capacity of three different demineralized bone matrix (DBM) products applied using different carrier molecules (hyaluronic acid [HA] vs. carboxymethylcellulose [CMC]) or bone compositions (cortical bone vs. cortical bone and cancellous bone) in a rabbit segmental defect model. Overall, 15-mm segmental defects in the left and right radiuses were created in 36 New Zea...

It is unclear if a decrease in cancellous bone density or cortical bone thickness is related to sacral insufficiency fractures. We hypothesized that reduction in overall bone density leads to local reductions in bone density and cortical thickness in cadaveric sacra that match clinically observed fracture patterns in patients with sacral insufficiency fractures. We used quantitative computed to...

Patients with monoclonal gammopathy of undetermined significance (MGUS) are at increased fracture risk, and we have previously shown that MGUS patients have altered trabecular bone microarchitecture compared with controls. However, there are no data on whether the porosity of cortical bone, which may play a greater role in bone strength and the occurrence of fractures, is increased in MGUS. Thu...
