Lower limb amputees often experience complications with the use of conventional socket-type prostheses, which further reduce their already compromised ability to perform the activities of daily living, or to participate in sporting activities. During the last two decades, a new technology of direct skeletal attachment (osseointegration) of prosthesis to the femoral residuum has been developed. The aim of this research was to assess the implant design, surgery protocols, and functional testing of this new technology on the first 100 patients using the Integral Leg Prosthesis procedure. This new knowledge can guide future engineering developments of osseointegration within the sporting arena. Between 1999 and 2013, direct skeletal implantation was performed on 112 amputees, from two centres in Germany and Australia. From the experience of the surgical team, modifications were made to the implant design. This re-engineering of the implant has reduced the surgical revisions due to infection from 29 % with the early implant design down to 7 %. The functional testing of the 34 Australian cases were assessed pre- and 12 months post-implant with significant improvements of one complete K-scale; the Q-TFA measures increased (50.9–86.7), whilst the Timed Up and Go decreased significantly (12.43 s ± 3.89 to 8.03 s ± 2.80), and the 6 min walk increased (304.0–383.9 m). From these findings, osseointegration technology is realistically the way of the future for amputee athletes. Further refinement of the implant design and sports-specific functional testing are required to define the potential of this technology. 相似文献

In the schools of the German Democratic Republic, the fostering of gifts and talents is regarded as (a) an integral component of a system emphasizing the unity of general education and special provision for the highly able, (b) a contribution to the development of the whole personality of gifted students and (c) part of the process of recognizing and fostering gifts and talents in all areas of human activity. Education of the gifted takes place in the schools in the form of integrated‐differentiated instruction (subject specific), of demanding out of school activities (interdisciplinary, project work) and of polytechnic education (oriented towards productive work). A longitudinal study in 8 schools with pupils from 12–16 years in age yielded findings on the interaction between in and out of school activities, on the dynamics of personality and performance development in gifted youngsters, and on sex differences in the process of promotion and development of gifts. The results support the value of integrated‐differentiated fostering of able students throughout their school years, but are against too early selection and channelling. 相似文献
