Development of a balanced experimental–computational approach to understanding the mechanics of proximal femur fractures

The majority of people who sustain hip fractures after a fall to the side would not have been identified using current screening techniques such as areal bone mineral density. Identifying them, however, is essential so that appropriate pharmacological or lifestyle interventions can be implemented. A protocol, demonstrated on a single specimen, is introduced, comprising the following components; in vitro biofidelic drop tower testing of a proximal femur; high-speed image analysis through digital image correlation; detailed accounting of the energy present during the drop tower test; organ level finite element simulations of the drop tower test; micro level finite element simulations of critical volumes of interest in the trabecular bone. Fracture in the femoral specimen initiated in the superior part of the neck. Measured fracture load was 3760 N, compared to 4871 N predicted based on the finite element analysis. Digital image correlation showed compressive surface strains as high as 7.1% prior to fracture. Voxel level results were consistent with high-speed video data and helped identify hidden local structural weaknesses. We found using a drop tower test protocol that a femoral neck fracture can be created with a fall velocity and energy representative of a sideways fall from standing. Additionally, we found that the nested explicit finite element method used allowed us to identify local structural weaknesses associated with femur fracture initiation.

EU development ministers discuss approach to Central Asia. EUCAM Commentary No. 16, July 2011

On 14 July European development ministers met in Sopot, Poland. Among a host of development related matters Central Asia was on the agenda and European Union Special Representative Pierre Morel and Development Commissioner Andris Piebalgs were invited to give political and development assistance oriented background to the European ministers. The Polish Presidency wants to devote special attention to EU development assistance to this often over-looked region, which the EU has traditionally viewed predominantly through a foreign policy lens. Development strategies to Central Asia need to be discussed in the context of the five year old political strategy, set to be reviewed this coming autumn.

Child development services: a multidisciplinary approach to professional education via videoconference

We have piloted a monthly series of multidisciplinary case discussions via videoconference in the area of child development. The project provided a forum for clinical discussion of complex cases, peer review, professional development and networking for allied health professionals and paediatricians. Six sites in Queensland participated in the project; each site presented at least one case for discussion. The videoconferences ran for 90 min each and were attended by an average of 26 health professionals. The response rate for a questionnaire survey was 71%. The respondents rated the effectiveness of case summaries and the follow-up newsletter very positively. Despite some early difficulties with the technical aspects of videoconferencing, the evaluation demonstrated the participants' satisfaction with the project and its relevance to their everyday practice.
