Model driven segmentation and the detection of bone fractures
… whether geometric criteria can be used to detect bone fractures from Computed Tomography data. Conventional image processing of CT data is aimed at the production of simple iso-surfaces for surgical planning or diagnosis - such methods are not suitable for the automated detection of fractures. Our …

Easily Applicable Fixation Method of Open Alveolar Bone Fractures in the Emergency Department
본 논문의 목적은 응급실에서 개방성 치조골 골절을 간편하게 고정하는 술기법을 연구하기 위함이었다. 저자는 2006년 1월부터 2006년 12월까지 본원 응급의료센터로 내원한 개방성 치조골 골절 환자를 대상으로 고정술의 효과를 비교하기 위하여 고정 후의 안정성, 교합상태, 출혈 정도, 시행 시간, 시행에 따른 어려운 점을 평가하였다. 총 8례가 본 연구의 대상이 되었으며, 모든 증례에서 고정술은 지혈에 효과적이었다. 각각의 환자는 고정술 후 확연한 출혈의 감소를 보였다. 4명의 환자는 철사를 이용하였고, 나머지 환자는 나일론봉합사를 …

Understanding the mechanism of injury associated with long bone fractures through dynamic bending impact
… reconstructions as it assumes that all butterfly fractures are produced due to bone failing in tension. Furthermore, it requires the presence of a detached piece in order to be applicable, which is also the case for other proposed methods. The current study explores the biomechanics involved in …

Bone Mineral Density In Hiv: A Comparison Of Hiv Positive Versus Negative Patient With Lower Limb Long Bone Fractures
… a global health issue causing a deterioration in bone microarchitecture, compromising bone strength. In South Africa (SA), the prevalence of osteoporosis is a growing concern for both HIV-positive and HIVnegative individuals. The aim of this study was to assess the impact of HIV infection on bone …

Non-invasive monitoring of bone health using ultrasound
Bone fractures are estimated to afflict everyone at least once in his/her lifetime. Monitoring this becomes crucial especially when it comes to athletes in order for them to safely resume their regular activities as soon as possible. Technologies currently employed are either very expensive or use …

Regional and Seasonal Effects on Long Bone Fracture Characteristics
… skeletal trauma to determine the timing of bone fractures. Differentiating between perimortem trauma and postmortem damage is especially complicated due to the variable timing of bone degradation and subsequent changes in fracture morphology. Different investigations into the timing at which …

A vitamin D enriched diet attenuates sex-specific behavioral deficits in the NS-Pten knockout mouse.
… spontaneous seizures are at a high risk for bone fractures as well as an increased likelihood of a comorbid diagnosis of Autism spectrum disorder. Additionally, individuals with epilepsy could have vitamin D deficiencies. The neural subset-specific (NS) Pten knockout (KO) mouse has shown …

Three-dimensional image reconstruction of skeletal tissue from computed tomography
… diagnosis of diseases such as cancer, tumors, bone fractures etc. depend on edge detection techniques to identify the malignant growths. In orthopedics, edge detection techniques are used in the reconstruction of the skeletal system from modalities such as MRI (magnetic resonance imaging) and …

MSC DERIVED EV IN REGENERATIVE MEDICINE
… patients suffering from osteoarthritis (OA) and bone fractures. Currently, there is no long-term therapy for OA; symptoms can be managed with anti-inflammatories and analgesics until they worsen to the extent that the damage becomes debilitating, and joint arthroplasty, is necessitated. However, …

Optimization of culture conditions for equine bone marrow mesenchymal stem cells and their differentiation into osteoblasts
… the animals is of great focus for horse owners. Bone fractures are an aspect of equine health failure that is continually catastrophic and often fatal. In addition to discussing fracture, this review will outline the process by which bone tissue is regularly maintained and self-healed. Also, …

Characterization and Implementation of Low Intensity Pulsed Ultrasound as a Tool to Apply Physical Load to Scaffolds and Bone Cells for Fracture Repair
<p>One current challenge in treating bone fractures is the effective treatment of non-unions and delayed unions. Low Intensity Pulsed Ultrasound (LIPUS) has been approved by the FDA to treat fresh fractures since 1994 and non-unions since 2000 and is an attractive treatment option because it is …

Diagnosis, epidemiology and immunologic consequences of copper deficiency in calves
… of copper disease include anemia, diarrhea, long bone fractures, generalized ill-thrift, and decreased fertility. Recent studies have demonstrated that copper deficiency is common in North American beef cattle. This body of work addresses diagnosis, epidemiology and the immunologic consequences of …

A Novel Use for Ionic Polymer Transducers for Ionic Sensing in Liquid
… has applications in the biomedical field for bone healing research. An ion sensor and a strain gauge could determine the effects of motion allowed at the fracture site, thus improving rehabilitation procedures for bone fractures. The charge sensitivity of the material and the capacitance of …

Computational modeling of trabecular bone in lower extremity injuries due to impact
… for a substantial number of lower extremity bone fractures. The Army Research Laboratory (ARL) concentrates part of its research efforts into better understanding impact related injuries. Despite a significant number of articles on bone mechanical behavior, only a few consider high strain …

Design of a Robotic Equine Forelimb for Testing Load-Bearing Rehabilitative Devices
Because horses are animals of flight, bone fractures in the horses' limbs are quite common. When foals fracture a bone in their leg, the healthy leg is often compromised. During convalescence, the animal tends to overstress the healthy leg in an attempt to relieve the stress on the injured leg. …

Evaluating Bone by Ultrasound
Bone fractures associated with osteoporosis, a major bone disease characterized by low density and high fracture risk, are common causes of disability and large medical care expenses around the world. Considering its low cost, high portability, and non-ionizing nature, non-invasive ultrasound …

DOES STRENGTH TRAINING IMPROVE MUSCULOSKELETAL HEALTH AND BODY COMPOSITION IN BLACK MEN WITH PROSTATE CANCER ON ANDROGEN DEPRIVATION THERAPY?
… concomitant increases in fat mass, fatigue, and bone fractures. Because strength training (ST) can reverse these factors in healthy older adults, it was hypothesized that ST would be effective in PCa patients on ADT but with an attenuated response. Therefore, the purpose of this study was 1) to …
