Comparison of cemented versus uncemented acetabular component positioning using an imageless navigation system
Chawda, Mayur , Hucker, Peter, Whitehouse, Sarah L., Crawford, Ross W., English, Hugh , & Donnelly, William J. (2008) Comparison of cemented versus uncemented acetabular component positioning using an imageless navigation system. Journal of Arthroplasty, 24(8), pp. 1170-1173.
Hip Navigation was used as an assessment tool to compare ability to reproduce trial and definitive acetabular placement in total hip replacement, using cemented and uncemented components. We demonstrated a significant difference in reproducibility between components. Four of 20 (20%) uncemented cups deviated from the target inclination by 5 degrees or more compared to none of 21 in the cemented group (p=0.048). Seven of the 20 (35%) of the uncemented cups deviated from the target version by 5 degrees or more compared to none of 21 in the cemented group (p=0.003). This may explain higher rates of revision for dislocation with uncemented components. There was also a significant difference between the groups with regard to deviation from planned leg length (p<0.001).
Impact and interest:
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.
