Purpose: The goal of this article is to present our experience on navigation for osteotomies around the knee and especially osteotomies for coronal deformities. The first computer-assisted osteotomy was performed in March 2001 and since that time more than 1000 osteotomies have been performed in our department.Methods: All the osteotomies were performed with the Orthopilot® device (B-Braun-Aesculap, Tuttlingen, Germany). The main indication was for genu varum deformities but several cases were operated for genu valgum. The surgical procedure as well as the indications and the rationale for each osteotomy (high tibial osteotomy-HTO, double-level osteotomy-DLO, femoral osteotomy-FO) are addressed in the article.Results: The results are focused on several papers published by the authors since more than 10 years. Regarding HTO for genu varum, the preoperative goal (HKA angle: 184° ± 2°) was reached in 96 % of cases and the difference was statistically significant compared to the non-navigated series (71 %: p < 0.05). Regarding DLO for genu varum, the preoperative goal was reached in 92.7 % for the HKA angle and in 88.1 % for the medial proximal tibial mechanical angle (MPTMA). Regarding genu valgum deformity, the preoperative goal was achieved in 86.2 % of cases for the HKA angle and 100 % of cases for the MPTMA.Conclusion: According to these results, one can say that, regardless the type of osteotomy, the procedure is reliable, reproducible and accurate. Since 15 years, all the osteotomies around the knee are navigated in our department. Provided that one uses a reproducible radiograph protocol, navigation allows to perform double-level osteotomies, both for genu varum and genu valgum, with optimal accuracy in order to avoid oblique joint line, which will be difficult to revise to TKA.Level Of Evidence: IV.

Background Since the introduction of electronic nursing documentation systems, its implementation in recent years has increased rapidly in Germany. The objectives of such systems are to save time, to improve information handling and to improve quality. To integrate IT in the daily working processes, the employee is the pivotal element. Therefore it is important to understand nurses' experience with IT implementation. At present the literature shows a lack of understanding exploring staff experiences within the implementation process. Methods A systematic review and meta-ethnographic synthesis of primary studies using qualitative methods was conducted in PubMed, CINAHL, and Cochrane. It adheres to the principles of the PRISMA statement. The studies were original, peer-reviewed articles from 2000 to 2013, focusing on computer-based nursing documentation in Residential Aged Care Facilities. Results The use of IT requires a different form of information processing. Some experience this new form of information processing as a benefit while others do not. The latter find it more difficult to enter data and this result in poor clinical documentation. Improvement in the quality of residents' records leads to an overall improvement in the quality of care. However, if the quality of those records is poor, some residents do not receive the necessary care. Furthermore, the length of time necessary to complete the documentation is a prominent theme within that process. Those who are more efficient with the electronic documentation demonstrate improved time management. For those who are less efficient with electronic documentation the information processing is perceived as time consuming. Normally, it is possible to experience benefits when using IT, but this depends on either promoting or hindering factors, e. g. ease of use and ability to use it, equipment availability and technical functionality, as well as attitude. Conclusions In summary, the findings showed that members of staff experience IT as a benefit when it simplifies their daily working routines and as a burden when it complicates their working processes. Whether IT complicates or simplifies their routines depends on influencing factors. The line between benefit and burden is semipermeable. The experiences differ according to duties and responsibilities. [ABSTRACT FROM AUTHOR]

Abstract The Second Information Technology in Education Study — Module 2 (SITES-M2) in Germany investigated 12 cases of innovative pedagogical practice using technology (IPPUT) in primary, lower and upper secondary schools. One theme that emerged from the analysis of these cases was students' cooperation. It seems that the co-occurrence of ICT-use and students' cooperation and collaboration is not accidental. The focus of this paper is an analysis and classification of the students' cooperation identified in the IPPUTs. [ABSTRACT FROM AUTHOR]

We examined the usage of computers in 171 adolescents with visual impairment and 515 sighted peers. Participants reported computer ownership and hours per week using the computer for school, video games, music, movies, photographs, searching for information, communication and shopping. Adolescents with visual impairment reported higher rates of overall computer usage than sighted peers, due to higher usage for school work and searching for information. In addition, adolescents who are blind used their computers more often for communication and less often for dealing with photographs than adolescents with low vision. Furthermore, higher usage of computer was associated with higher age, male gender, lower vision status and worse marks in school. Finally, positive associations between computer use and having a romantic partner as well as belonging to a peer-group were stronger in adolescents with visual impairment than in sighted adolescents. Conclusions for further research are discussed. [ABSTRACT FROM AUTHOR]
