In this paper, we present a preliminary study dealing with the importance of correct modeling of connective tissues such as ligaments in laparoscopic liver surgery simulation. We show that the model of these tissues has a significant impact on the overall results of the simulation. This is demonstrated numerically using two different scenarios from the laparoscopic liver surgery, both resulting...

The size and shape of occupants dictates their biomechanical response in any frontal crash. Seatbelt is the primary occupant restraint equipment that reduces risk of serious injuries. The biomechanical response of the occupant is further improved in presence of airbag and advance technologies such as load limiter and pretensioner. Sufficient research and tests are available to assess the biomec...

background patients who have shoulder pain usually have compensatory or contributory deviation of shoulder motion during arm elevation. in the traditional scapulohumeral rhythm, the share of the acromioclavicular (ac) and the sternoclavicular (sc) joint movements and also the role of ac internal rotation angle are unknown. objectives the main purpose of this study was to measure and compare the...

Biomechanical stability is the primary function of the acetabular labrum. It provides a hip suction seal and optimal joint function. Labral tears are a common reason for hip arthroscopy, to improve patient function and to prevent long-term degenerative arthropathy. Arthroscopic labral repair has shown significantly better outcomes in return to premorbid activity levels when compared with labral...

background : lifting methods, including standing stance and techniques have wide effects on spine loading and stability. previous studies explored lifting techniques in many biomechanical terms and documented changes in muscular and postural response of body as a function of techniques .however, the impact of standing stance and lifting technique on human musculoskeletal had not been investigat...

Selecting appropriate technology strategy is crucial to those designing ICT-based offering for specific geographical market. The antecedents of adopting particular technology can be used to identify opportunities and barriers of entry, but further information is needed for technology management on how adoption would take place. In this paper, it is argued that deploying a scenario method facili...

A myriad of orthopaedic injuries require surgical fixation of torn connective tissue to an osseous insertion site with either direct repair or reconstruction with a soft-tissue graft. Numerous factors influence the strength of a soft-tissue-to-bone fixation construct, including tissue quality, implant strength, contact area and pressure, and tensioning. Each fixation technique differs with resp...

Obtaining proper occupant restraint fit when using a wheelchair as a motor vehicle seat is often difficult to attain with vehicle-mounted restraint systems. The comprehensive evaluation conducted in this study illustrates the occupant crash protection benefits of wheelchair-integrated restraint systems, as compared to vehicle-mounted restraint systems. Using computer crash simulation, occupant ...

results in this study, a significant relation was established between the three areas or domains of learning: 1) knowledge domain (learning the theoretical basis of necessity-based training); 2) motivational domain (how to motivate collection, classification, etc. and 3) the technical domain (how trauma experts and specialists can recognize and classify needs practically. our findings suggest t...
