Objectives:

To gain an understanding of the current issues surrounding falls prevention across Europe and to embrace at national and international level, the different political and health service agendas in each country such that recommendations can ultimately be translated into working models of practice in each country.

Description of work: This work package focuses on the development of a consensus approach to the assessment and management of falls in older people across Europe. Fundamental to this process is the development of a clear understanding of how services across Europe are currently configured and what the national and international drivers for change might be over the next 5–10yrs. The ultimate aim is to be able to facilitate the development of a set of comparable assessment and outcome measures to be used in a large randomised controlled trial with fracture as the primary outcome measure. Year 1. Whilst undertaking the networking exercise in year 1, members had the opportunity to visit key individuals in European countries and anticipate the potential opportunities and constraints of developing and delivering falls services in a co-ordinated and comprehensive fashion. Year 2 focuses on the development of assessment tools, which can be tailored so as to be applied in a variety of clinical settings from community based assessment to the highly specialised investigation units. The work package links closely with other work packages on balance and gait and psychology to ensure consensus in recommendations. In addition to the recommendations for clinical assessment and management, the work package also provides advice and guidance on evaluation and audit of services and as such links closely with the taxonomy work. Recommendations are to be peer reviewed. Year 3 entails the collation of agreed assessment and evaluation methods and the translation of the recommendations into a format for dissemination including written documentation translated into a number of different languages and an interactive website with links to relevant organisation across Europe and the rest of the world. Year 4. During the final year, members of the work package take responsibility for the dissemination of the work to clinical colleagues.

Objectives: The development of effective fall prevention programs requires understanding of underlying causes of falls. Measurement tools are needed that predict the risk of falling and give objective assessment of balance function needed for daily life performance. The ultimate goal of the activities within this work package is to combine the expertise of different disciplines for the development of balance assessment tools that meet the requirements for large-scale intervention studies and routine-use in clinical settings. The knowledge needed to develop these instruments and measures is scattered over a wide range of disciplines (ranging from physiology to electrical engineering). The objectives of this work package are to combine expertise from different disciplines to transfer knowledge between disciplines, to co-operate in designing research and provide an intellectual environment for interdisciplinary projects and dissemination of knowledge into disciplines working in the clinical field.

Description of work: Recent technological developments allow for the measurement of human movement under real-life conditions by means of lightweight ambulatory equipment. This novel approach to the analysis of human movement can potentially fill the need for objective field instruments. However, suitable methods for balance assessment need to be developed. Activities of this work package are aimed at co-ordinating the development of methods that can be used in the clinical field for assessment of posture and gait. The work encompasses the organization of workshops, the co-ordination of research, and dissemination of knowledge through publications, teaching and training. Members co-ordinate their individual research efforts in such a way that the different research lines support and reinforce each other. The coordination of research will involve joint experiments and the definition of assessment protocols that can be used in the individual studies of all participating groups. The work focuses on the analysis of kinematic patterns during walking and standing in a natural environment by means of ambulatory equipment. Appropriate methods for signal acquisition and analysis are being developed. Protocols are being designed which specifically address different aspects of balance control (i.e. mental load, sensory dependence, and effects of mechanical manipulations). Laboratory tasks, which have proven to be sensitive for balance dysfunction, will be translated into valid, reliable and easy-to-use procedures for field use. These field instruments are based upon a sound theoretical framework against which the results can be understood and interpreted. In order to address the validity and predictive value of field instruments, longitudinal studies need to be performed that are in accordance with the work in other work packages. Apart from balance assessment procedures, activity levels, history of falls, and future falls need to be assessed. We expect this novel approach to give insight in the relation between objective measures of balance function, activity level and number of falls. Thus, the occurrence of falls can be related to (changes in) activity level.

Introduction: Randomised Controlled Trials (RCTs) of interventions to reduce the incidence of falls have used a variety of methods to define and measure outcomes. A standardised approach to defining and measuring outcomes, and a shared taxonomy of interventions is a prerequisite to interpret and disseminate the findings of studies.

Method: We agreed to focus on five areas: falls, injuries, psychological consequences, physical activity and quality of life. A systematic literature review has been performed to identify outcome definitions currently used in RCTs and is focusing on the quality of outcome measures in terms of reliability, validity and acceptability. A consensus building process is being performed using a modified nominal group technique to define a core set of outcome definitions and measures, which can then be piloted in a number of sites across Europe. Where consensus cannot be achieved, suggestions are made for future research to develop and/or appraise new methods of measurement and these will feed into future revisions of the recommendations. The taxonomy of interventions is being developed in parallel with this process.

Results: The presentation will demonstrate how varying methods of defining falls can lead to a different interpretation of trial results and suggest a range of definitions than might be included in future trials. We consider the number of falls, number of fallers, time to first fall, and fractures per fall ratios as examples.

Conclusions: An agreed and standardised set of outcome definitions and measures is important to improve the robustness of data from intervention studies, will enable comparison across studies, good quality measurement in multi-centre trials, and facilitate meta-analysis of trial results. A taxonomy of interventions facilitates comparisons between studies, helps to determine the most effective components or sub-components of interventions, and aids the decision making process of policy makers and health insurance plans.

Background: Tibial plafond fractures are caused by severe axial compression forces and are associated with soft tissue injuries. These fractures are difficult to treat and the risk of complications is high. Methods and Materials: A retrospective study of tibial plafond fractures was performed at our hospital between 2003 and 2009 and 51 patients were evaluated (51 fractures). The fracture type was classified according to the OTA classification system. 10 fractures were described as type A fractures (A1 = 3, A2 = 3, A3 = 4) (19.60%), 15 were type B fractures (B1 = 0, B2 = 9, B3 = 6) (29.4%) and 26 were type C fractures (C1= 3, C2=13, C3 = 10) (51%). Results: The average age was 47.8 years. Cases comprised 25 accidental falls (49%), 13 traffic accidents, (2.5%), 7 autolysis attempts (13.7%), 4 sports accidents (7.8%) and 2 industrial accidents (3.9%). 15 patients were initially treated with external fixators, mainly those who had type C fractures and fractures where the soft tissues were seriously damaged (21.6%). Subsequently the tibia was treated with plate fixation. Mean follow-up period was 87.78 months. Patients were required to fill in 2 quality life questionnaires after the surgical treatment. results obtained with both scales (AOFAS and FFI) were compared. The complications rate was 14%. The main complications were superficial infections, posttraumatic arthritis and non-union fractures. One case presented a superficial infection (2%) and 6 patients suffered deep infections (11.8%). Worst scores were observed in both scales with patients treated with type C fractures of the AO classification. Conclusions:. - Type C fractures have a worse prognosis. - Using external fixators as initial stabilisation method improves the healing of soft tissues. - It is important to perform a CT scan in the preoperative planification. - Tibial plafond fractures are still a challenge for the surgeon

Between 1982 and 2000, 37 cases of fractures of the odontoid process were treated at Hirosaki University Hospital. There were 16 females and 21 males, with an average age of 43.9 and 37.7 respectively. Twenty-three of 37 were type II and 14 were type III by the classification of Anderson and D’Alonzo. Eight of type II were old fractures. Nineteen of them were injured in traffic accidents, 9 in accidental falls from a height, 4 by falling down, 2 in lumbering accidents and 3 by unknown causes. Severe neurological disorders were recognized in 7, mild in 12 and 22 had no neurological disorders. Neurological disorders were correlated with SAC (space available for spinal cord) at C1-2. Twenty-two of type II (95.7%) and 10 of type III (71%) were treated surgically. Surgical methods were anterior screw fixation of the odontoid process in 7, anterior atlanto-axial joint fixation in 3, posterior atlanto-axial joint fixation in 5, posterior occipito-cervical fusion in 3, anterior and posterior combined fixation of the atlanto-axial joint in 2 and others in 2. Bone union was obtained in 18 (81.8%) of type II and 10 (100%) of type III by the primary operations. There was no nonunion in anterior screw fixation cases. Nonunion occured in one of type II (100%) and 2 of type III (50%) treated nonoperatively. Two of them were operated for nonunion. One of them remained nonunion by two additional operations. No case of nonunion showed neurological deterioration for 91.8 months after treatment on average. Anterior direct screw fixation of the odontoid process is superior to the other methods in the point of immobilization of the odontoid fragment without limiting the motion of the atlanto-axial joint. We recommend anterior direct screw fixation of the odontoid process as a first choice of the surgical method for fresh fractures of the odontoid process in cases with reduced fragments
