Periacetabular osteotomy through the pararectus approach: technical feasibility and control of fragment mobility by a validated surgical navigation system in a cadaver experiment

PURPOSE The pararectus approach has been validated for managing acetabular fractures. We hypothesised it might be an alternative approach for performing periacetabular osteotomy (PAO). METHODS Using four cadaver specimens, we randomly performed PAO through either the pararectus or a modified Smith-Petersen (SP) approach. We assessed technical feasibility and safety. Furthermore, we controlled fragment mobility using a surgical navigation system and compared mobility between approaches. The navigation system's accuracy was tested by cross-examination with validated preoperative planning software. RESULTS The pararectus approach is technically feasible, allowing for adequate exposure, safe osteotomies and excellent control of structures at risk. Fragment mobility is equal to that achieved through the SP approach. Validation of these measurements yielded a mean difference of less <1 mm without statistical significance. CONCLUSION Experimental data suggests the pararectus approach might be an alternative approach for performing PAO. Clinical validation is necessary to confirm these promising preliminary results.

Assessment of Socio-Economic and Climate Change Effects on Water Resources and Agriculture in Southern and Eastern Mediterranean countries. MEDPRO Technical Paper No. 28/March 2013

This study aims at assessing the socio-economic and environmental effects of different societal and human development scenarios and climate change in the water-scarce southern and eastern Mediterranean. The study develops a two-stage modelling methodology that includes an econometric analysis for the southern and eastern Mediterranean region as a whole and a detailed, integrated socioecological assessment focusing on Jordan, Syria and Morocco. The results show that water resources will be under increasing stress in future years. In spite of country differences, a future path of sustainable development is possible in the region. Water withdrawals could decrease, preserving renewable water resources and reversing the negative effects on agricultural production and rural society. This, however, requires a combination across the region of technical, managerial, economic, social and institutional changes that together foster a substantive structural change. A balanced implementation of water supply-enhancing and demand-management measures along with improved governance are key to attaining a cost-effective sustainable future in which economic growth, a population increase and trade expansion are compatible with the conservation of water resources.

The Relationship between Energy and Socio-Economic Development in the Southern and Eastern Mediterranean. MEDPRO Technical Report No. 27/February 2013

This report aims to identify, explain and detail the links and interactions in southern and eastern Mediterranean countries (SEMCs) between energy supply and demand and socio-economic development, as well as the potential role of energy supply and demand policies on both. Another related aim is to identify and analyse, in a quantitative and qualitative way, the changing role of energy (both demand and supply) in southern Mediterranean economies, focusing on its positive and negative impact on socio-economic development. This report investigates in particular: o The most important channels through which resource wealth can contribute to or hamper economic and social development in the analysed region; o Mechanisms and channels of relations between energy supply and demand policies and economic and social development. The burdens of energy subsidies and ‘oil syndrome’ are of particular relevance for the region. An integrated socio-economic development and energy policy scenario approach showing the potential benefits and synergies within countries and the region is developed in the final part of the report.

Egypt: Changes and Challenges of Political Transition. MEDPRO Technical Report No. 4/May 2011

Hosni Mubarak’s regime and its power system enjoyed remarkable stability for over 30 years. On 11 February 2011, after 18 days of mass protests, the Egyptian president was forced to step down, revealing the unsustainability of the political and economic system that had ensured his continuity for so long. While the revolution of January 25th led to a major success – the fall of Hosni Mubarak – Egypt’s political future is still opaque and exposed to a number of risks. This paper first highlights the factors underpinning the former stability of Mubarak’s regime; it then assesses the causes of its underlying unsustainability, leading to the anti-government popular mobilisation in January-February 2011 and the removal of Mubarak; finally the paper evaluates the prospects for a genuine democratic transition in Egypt, by looking at the main political and socio-economic challenges facing the country.
