Loading Applied on Trans-Femoral Osseointegrated Prostheses
Lee, Winson C.C., Frossard, Laurent A., & Branemark, Rickard (2006) Loading Applied on Trans-Femoral Osseointegrated Prostheses. In Dillon, Michael (Ed.) 30th Annual Scientific Meeting of the International Society for Prosthetics and Orthotics, October, Perth, Australia.
A lower-limb prosthesis is conventionally attached to the residual limb by a socket and often some suspension devices. Although this approach has been used for over 50 years, previous studies have pointed the phenomena that local limb pain and soft tissue breakdown are common. High pressure applied from the prosthetic socket onto the residual limb is the major cause of the problems.
Researchers are developing a surgical approach using osseointegration for directly connecting a prosthesis into the femur using a fixation system with a titanium implant. The absence of a prosthetic socket can alleviate the skin problems. This procedure increased significantly the quality of life of amputees. However, the current rehabilitation is long and some occasional mechanical failures of the fixation following a fall were reported. Understanding the load applied on the osseointegrated fixation is one important step to solve these problems.
This article presents the load applied on the fixation of twelve trans-femoral amputees during level walking.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
