Abstract

A randomized controlled trial was performed to assess the effect of a rim cutter device on cement mantles in modern elective total hip replacement using a flanged acetabular component. Forty patients were randomized to a rim cutter (21) or control (19) group. A statistically significant improvement in cement penetration was demonstrated in zone 1 (10.1 versus 8.6mm (p=0.023)), and in cement mantle thickness in zones 2 and 3 (7.8mm and 6.7mm versus 5.7 and 5.4mm (p<0.001 and p=0.017); with a reduced incidence of bottoming out of the socket (1/21 versus 8/19 (p=0.007). Cement mantle thicknesses greater than 8mm were achieved more consistently in the rim cutter group (30% versus 2%). This technique improves cement penetration and mantle thickness in a reliable manner.

Citation countsare sourced monthly from Scopus and Web of Science® 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.
