Static load bearing during early rehabilitation of transfemoral amputees using osseointegrated fixation
Cairns, Nicola J., Frossard, Laurent A., Hagberg, Kerstin, & Branemark, Rickard (2006) Static load bearing during early rehabilitation of transfemoral amputees using osseointegrated fixation. In Dillon, Michael (Ed.) 30th Annual Scientific Meeting of the International Society for Prosthetics and Orthotics, Oct, Perth, Australia.
Many transfemoral amputees wearing conventional socket prostheses experience pain related to the socket-residuum interface and difficulties with socket retention or fit due to a short residuum. In consideration of these problems a direct skeletal fixation method has been developed whereby a titanium implant is screwed into the medullary canal of the residual femur. Prosthetic components are directly attached to the fixation, once osseointegrated, removing the need for a prosthetic socket. The rehabilitation program to return to ambulation involves incremental static loading of the fixation until full weight bearing is achieved. The rate of loading, which is intended to be isolated to the long axis of the fixation, is determined by the quality of the residual skeleton and a qualitative assessment of the pain experienced by the amputee on loading. Rotational loading of the implant is to be avoided at this stage. The amputee uses a domestic weigh-scale to provide feedback of the load applied. This study aims to measure the true load applied to the fixation and compare this with the clinically prescribed axial load.
Impact and interest:
Citation counts are sourced monthly from and 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 downloads displays 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.
