A prospective evaluation of bone mineral density measurement in females who have fallen
(2003)
Kenny, Rose
Abstract:
doi: https://doi.org/10.1093/ageing/afg062
Background: the National Service Framework for Older Persons recognises the relationship between falls and osteoporosis; however, the best method for the evaluation of bone mineral density measurement in fallers is unclear. Dual energy X-ray absorptiometry of lumbar spine and hip is the gold standard for bone mineral density measurement, but is time consuming and may not be readily available. A cheaper, more portable alternative is peripheral dual energy X-ray absorptiometry of the heel. This predicts overall fracture risk as effectively as dual X-ray at the spine and hip,although site speciWc measurements provide the best estimate of fracture risk at a particular location. Aims: 1. To validate peripheral dual energy X-ray in fallers by comparing heel bone mineral density measurement with measurements obtained at the lumbar spine and hip. 2. To determine the prevalence of osteoporosis in an unselected cohort of fallers...

Abstract:
The original publication is available at http://www.sciencedirect.com
Fatigue-induced damage plays an important role in bone remodelling and in the formation of stress and fragility fractures. Recently, a technique has been developed (Lee, T.C. et al., Sequential labelling of microdamage in bone using chelating agents. Journal of Orthopedic Research, 18 (2000) 322-325) which allows microcrack growth in trabecular bone to be monitored by the application of a series of chelating fluorochromes, however, some limitations were identified with the process. The aims of this study were to refine the method of detection using these agents in order to determine the optimal sequence of application and the optimal concentrations which allowed all the agents to fluoresce equally brightly using UV epifluorescence. A chemical analysis process, ion chromatography, followed by validation tests on bone samples showed that the optimal sequence of application and concentration of each agent was al...

Abstract:

Fatigue-induced microdamage in bone contributes to stress and fragility fractures and acts as a stimulus for bone remodelling. Detecting such microdamage is difficult as pre-existing microdamage sustained in vivo must be differentiated from artefactual damage incurred during specimen preparation. This was addressed by bulk staining specimens in alcohol-soluble basic fuchsin dye, but cutting and grinding them in an aqueous medium. Nonetheless, some artefactual cracks are partially stained and careful observation under transmitted light, or epifluorescence microscopy, is required. Fuchsin lodges in cracks, but is not site-specific. Cracks are discontinuities in the calcium-rich bone matrix and chelating agents, which bind calcium, can selectively label them. Oxytetracycline, alizarin complexone, calcein, calcein blue and xylenol orange all selectively bind microcracks and, as they fluoresce at different wavelengths an...

<p>It is well known that bone contains small cracks; in vivo these microcracks are constantly growing and being repaired. Too rapid crack growth leads to stress fractures or fragility fractures. In vitro, changes occur in this population of microcracks when subjected to cyclic loading up to and including failure. Normally, the only parameters reported from such investigations are the number density of cracks and their average length. In the present work we examined the microcrack population in more detail. We analysed ten different sets of experimental data including in vivo and in vitro...

Abstract:
Background and Purpose— The FOCUS trial (Fluoxetine or Control Under Supervision) showed that fluoxetine did not improve modified Rankin Scale scores (mRS) but increased the risk of fractures. We aimed to describe the fractures, their impact on mRS and factors associated with fracture risk. Methods— A United Kingdom, multicenter, parallel-group, randomized, placebo-controlled trial. Patients ≥18 years with a clinical stroke and persisting deficit assessed 2 to 15 days after onset were eligible. Consenting patients were allocated fluoxetine 20 mg or matching placebo for 6 months. The primary outcome was the mRS at 6 months and secondary outcomes included fractures. Results— Sixty-five of 3127 (2.1%) patients had 67 fractures within 6 months of randomization; 43 assigned fluoxetine and 22 placebo. Fifty-nine (90.8%) had fallen and 26 (40%) had fractured their neck of femur. The effect of fluoxetine on mRS (common odds ratio =0.951) was not significantly altered by excluding fracture p...

Fractures interpreted from acoustic formation imaging technology: Correlation to permeability
(2017)
McLean, K.; McNamara, David D.
Abstract:
Permeable feed zones in geothermal wells are commonly identified using well profiles of temperature, pressure and fluid velocity measured at different injection rates during well completion testing and heat-up. While this data gives some indication of the depth and relative strength of the feed zones it does not give any information on the nature of the permeability in those zones, be it primary or secondary. Fracturing is thought to contribute to permeability in areas targeted for deep reinjection in the Wairakei geothermal system, within the Tahorakuri and Waikora Formations. By characterizing those deep fractures in terms of orientation, density and aperture, as well as determining the orientation of the horizontal stress field it is possible to interpret the fracture component of the well permeability. This has implications both for well targeting and reservoir modelling. The recent use of high temperature acoustic formation imaging technology (AFIT) can provide the necessary fr...

Abstract:
Atypical femur fractures (AFFs) are associated with long-term bisphosphonate (BP) therapy. Early identification of AFF prior to their completion provides an opportunity to intervene, potentially reducing morbidity associated with these fractures. Single-energy X-ray absorptiometry (SE) is an imaging method recently shown to detect incomplete AFF (iAFF) prior to fracture completion.

National Office of Clinical Audit
Abstract:
Welcome to the Irish Hip Fracture Database (IHFD) National Report 2016. This fourth IHFD report details 3,159 hip fracture cases in patients aged 60 years and over, discharged by 16 hospitals in 2016, which accounts for 86% of all hip fracture cases nationally*. This will be the first report to compare individual hospital performances across six clinical care standards. Since its inception in 2012 and with more than 10,000 patient records on the database, the IHFD is now a powerful resource. The IHFD has a clear focus on driving improvements in patient care and data quality. As a maturing database, its remit has naturally broadened and the ability of the database to influence other areas has also grown e.g. national service re-design, research etc.

Abstract:

Fatigue damage in bone occurs in the form of microcracks. This microdamage contributes to the formation of stress fractures and acts as a stimulus for bone remodelling. A technique has been developed, which allows microcrack growth to be monitored during the course of a fatigue test by the application of a series of fluorescent chelating agents. Specimens were taken from bovine tibiae and fatigue tested in cyclic compression at a stress range of 80MPa. The specimens were stained before testing with alizarin and up to three other chelating agents were applied during testing to label microcracks formed at different times. Microcracks initiated in interstitial bone in the early part of a specimen's life. Further accumulation of microcracks is then suppressed until the period late in the specimen's life. Microcracks were found to be longer in the longitudinal than in the transverse direction. Only a small pr...

Modelling fluid flow through fractured rock: Examples using TVZ geothermal reservoirs
(2017)
Kissling, W.M.; Ellis, S.E.; McNamara, David D.
Abstract:
Geothermal resources are often hosted within volcanic, plutonic, and basement-type lithologies. As such their matrix permeability can be very low and the transport and circulation of geothermal fluids will be dominated by fractures. Understanding the flow of hydrothermal fluid through fractured rock is thus essential to the efficient utilisation of New Zealand's deeper geothermal resources which are hosted in greywacke basement and lavas. In this study we investigate the nature of fluid flow for a variety of simple, single-and multiple-fracture arrangements and widths within Taupo Volcanic Zone (TVZ) greywacke basement and andesite hosted reservoirs, making use of known permeabilities. We present preliminary numerical models of fluid flow through a metre-scale sample of rock for a variety of simple fracture networks, with emphasis on the perturbation of the total flow across the sample with respect to that of a non-fractured sample. Later work will focus on the changes in fract...

Statistical corrections of fracture sampling bias in boreholes from acoustic televiewer logs
(2017)
Massiot, C.; Lewis, B.; Price, L.; Bignall, G.; McNamara, David D.
Abstract:
Targeting structurally controlled permeability remains a challenge in high temperature geothermal fields, because of the difficulties in characterising faults and fractures and their behaviour within the reservoir. The large-scale structural framework of a reservoir is usually well defined from offsets of key marker stratigraphic units intersected by wells. Some of these large-scale faults significantly contribute to reservoir permeability. Smaller-scale structures, particularly inferred active fractures, are also of major importance for the vertical and lateral flow of fluid within fractured formations. To identify the structures directly within the formations, acoustic televiewer logs are acquired in New Zealand geothermal fields with the advent of the Acoustic Formation Imaging Technology (AFIT) tool, which is rated to 300°C. This wireline logging tool acquires a full 360° acoustic image of the inside of the borehole. Typically, fractures have different acoustic impedances from t...

Sternal metastasis - the forgotten column and its effect on thoracic spine stability

Abstract:
Sternal metastases are not studied extensively in the literature. There is a paucity of information on their role in metastatic disease. The concept of the fourth column was described by Berg in 1993, and has been proven in case report, clinically and biomechanical studies. The role of the sternum as a support to the thoracic spine is well documented in the trauma patients, but not much is known about its role in cancer patients. This review examines what is known on the role of the fourth column. Following this we have identified two likely scenarios that sternal metastases may impact management: (1) sternal pathological fracture increases the mobility of the semirigid thorax with the loss of the biomechanical support of the sternum-rib-thoracic spine complex; and (2) a sternal metastasis increases the risk of fracture, and while being medical treated the thoracic spine should be monitored for acute kyphosis and neurological injury secondarily to the insufficiency of the fourth col...

Abstract:
This article is available at http://www3.interscience.wiley.com
Osteonal bone is often compared to a composite material and to metals as discontinuities within the material may provide sites of stress concentration for crack initiation and serve as barriers to crack growth. However, little experimental data exist to back up these hypotheses. Fluorescent chelating agents were applied at specific intervals to bone specimens fatigue tested in cyclic compression at a stress range of 80 MPa. The failed specimens were sectioned and labelled microcracks identified using UV epifluorescence microscopy. Microcrack lengths were measured and their relationship to cement lines surrounding secondary osteons recorded. Microcrack length at the time of encountering a cement line was also measured. Microcracks of less than 100mum stopped growing when they encountered a cement line. Microcracks of greater than 100mum in length continued to grow after encountering a cement line surrounding an osteo...

Abstract:
<p>Animal fracture models have been extensively applied to pre-clinical research as a platform to identify and characterize normal and abnormal physiological processes and develop specific maneuvers that alter the biology and biomechanics being examined. The choice of animal model employed in a study bears a direct relationship to the specific intervention being analyzed. The animal models employed should be described clearly, control group data should be established and reproducibility should be defined from experiment to experiment and from institution to institution so that quantitative and qualitative outcomes can be reliably compared and contrasted to other related studies.</p>

Abstract:
Wrist torus fractures in children are a frequent reason for Emergency Department (ED) visits. Torus fractures traditionally were treated with a backslab cast in the Children's ED and then referred to the Fracture Clinic. Guidelines were developed in order to standardise the care for children who attended the ED with a torus fracture. All patients who were seen & treated by the Advanced Nurse Practitioner (ANP) over a one year period with a diagnosis of a torus fracture were treated with immobilisation in a softcast. 119 patients met the criteria for inclusion. There were no adverse events recorded and no patient required subsequent visits to the Fracture Clinic. There was a cost savings of 18596 as compared with the normal referral pathway to the Fracture Clinic.

Microdamage in bone contributes to the loss of bone quality in osteoporosis and is thought to play a major role in both fragility and stress fractures (Schaffler et al. 1995). In this study, in vivo microcracks in human ribs were bulk-stained in basic fuchsin and viewed in longitudinal section and in 3 dimensions using 2 different computer-based methods of reconstruction: (1) serial sectioning of methylmethacrylate embedded sections using a sledge macrotome and identification of microcracks using UV epifluorescence followed by computerised reconstruction of microcracks using software and (2) laser scanning confocal microscopy of thick sections followed by reconstruction of microcracks into a 3-D image. The size and shape of microcracks were found to be similar using both techniques. Both techniques of reconstruction showed microcracks to be approximately elliptical in shape. From the serial sectioning re...
