The workshop is conducted by specialists with many years of personal experience in biomechanics and its application in clinic and research. The workshop is ideal for clinicians and engineers who want to acquire or refresh knowledge about the basics of biomechanic motion analysis.
Chairs: A. Janss (Aachen/DE) ; K. Radermacher (Aachen/DE)
International regulations and standards emphasize the importance of an early implementation of a consistent usability engineering process including human error risk management and validation (IEC 62366, 60601-1-6). Whereas CAOS solutions may offer fascinating surgical options and innovative technical features, the increasing complexity of surgical worksystems and human-technology interaction potentially increases the risk of human related adverse events as reported in many studies. The main usability criteria being effectiveness, efficiency, learnability and user satisfaction are of major importance for the therapeutic as well as commercial success of any technical solution. The workshop is ideal if you want to acquire or refresh knowledge about the basics of usability engineering and related methods – including an introduction and hands-on demonstration of  tools and methods for computer assisted risk analysis (FMEA, FTA) and HiFEM usability and human risk analysis.
Chairs: M. de la Fuente (Aachen/DE); C. Hänisch (Aachen/DE)
CAOS research groups all over the world are using a large variety of tools and methods for their research. Original concepts are proprosed by many group, however these developments are in many cases based on similar basic software solutions (e.g. image processing), tools, data sets and devices that are not available on an open access basis and have to be implemented or acquired by each group individually worldwide. Networking and exchange could reduce redundancy of basic developments and could provide much larger databasis e.g. of software solutions as well as image data sets e.g. for statistical morphological or biomechanical modelling.

Chairs: R. Schuhmacher (Basel/CH); L. Jauer (Aachen/DE)
Additive manufacturing technologies (also callled e.g. "3D-Printing") have been available since more than 30 years and first applications in medicine and especially orthopaedics and craniofacial surgery have been reported in the late 1980th. Recently, technological progress and the broad availability of different techniques for processing not only autoclavable and biocompatible polymers but also ceramics and different metal alloys such titanium, cobalt chrome or magnesium - or even 3D-bioprinting of e.g. living cartilage tissue – led to an exponential growth of interest and applications also in orthopaedics. Together with modern 3D-imaging, computer based reconstruction, planning and simulation techniques, additive manufacturing opened the door towards an efficient manufacturing of patient specific instruments and implants as well as novel therapy concepts.  The goal of this workshop is to introduce into basics of additive manufacturing, techniques, materials and potentials.  The workshop is conducted by specialists with many years of personal experience, providing examples from different perspectives. The workshop is ideal for clinicians and engineers who want to acquire or refresh knowledge about additive manufacturing technologies in clinical application and research.

Advanced Workshops
June 14, 2016 | 13:00–14:30

Chairs: J. Eschweiler (Aachen/DE); C. Hurschler (Hannover/DE)
Biomechanic modelling, computer based as well as experimental simulation are essential tools for the development, verification and validation of new implants and surgical therapy concepts in orthopaedics. Novel concepts of computer and robot based hardware-in-the-loop (HIL) simulators provide an even higher flexibility e.g. in terms of model based experimental multi-parameter studies. The goal of the two advanced educational workshops on biomechanics (A1: hip & knee /spine; A5: shoulder & wrist) is to discuss actual approaches in this domain and its potential in the Computer Assisted Orthopaedic Science and Surgery.
Chairs: K. Schmieder (Bochum/DE); M. Winking (Osnabrück/DE)
Spine surgery has been one of the first areas addressed in CAOS. Different techniques including 2D and 3D imaging, navigation, robotics, patient specific instruments have been proposed and partially introduced into clinical routine. Although, - similar to other CAOS applications – the initial peak of inflated expectations was followed by a valley of disillusionment, today especially computer assisted navigation has been established in clinical routine use in many hospitals. Recent industrial developments show even a revival of robot technologies and other approaches in this domain. The goal of this workshop in cooperation with the German Spine Society (DWG) is to discuss pros and cons and clinical experiences. The workshop is conducted by clinical specialists with many years of personal experience with different CAOS techniques, providing examples from different perspectives.  
Chairs: Y. Sato (Osaka/JP); G. Zheng (Bern/CH)
Statistical modelling of morphological and functional parameters potentially enables a significantly higher efficiency of complex patient specific modelling and model based CAOS. The increase of efficiency is related e.g. to a reduced requirement of e.g. acquisition and/or time consuming interactive segmentation of patient specific image data. Moreover, annotated statistical models enable the efficient and even automatic fusion of patient specific morphology with generic apriori knowledge models on functional aspects such as biomechanics as well as on surgical procedures, instruments or implants respectively. Whereas early work suffered from limited availability of statistical knowledge on pathological situations (e.g. 3D image data on anatomy), the broader clinical application of CAOS techniques also led to a more systematic digital archiving and availability of big amount of digital (3D) data on pathologies providing a more solid basis for statistical modelling. The workshop is conducted by specialists with many years of personal experience in statistical modelling in CAOS, providing examples from different perspectives.
Chairs: P. Meere (New York/USA); W. Lauer (Bonn/DE)
Recent developments– namely the universalized availability of smartphones, smart watches tablet and other smart devices – enable a new field of innovations in CAOS. Smartphones represent increasingly powerful computers, multifunctional sensory, wireless device communication and personal/local/global networking of things as well webbased multiuser and multicentre communication with central facilities and databases – to the hands of almost every patient, clinical practitioner or researcher. Concepts for apps using smart phones as sensor-integrated tools for clinical examination, surgical planning or follow-up surveys,  teleconsultance and telemonitoring e.g. in rehabilitation, activity tracking are available or under development and providing another fascination facet of computer assistance. The goal of the workshop is to present and discuss concepts and potentials as well as regulatory aspects of this upcoming field of CAOS.
