Abstract

The standard Exeter stem has a length of 150mm with offsets 37.5mm to 56mm. Shorter stems of lengths 95mm, 115mm and 125mm with offsets 35.5mm or less are available for patients with smaller femurs. Concern has been raised regarding the behaviour of the smaller implants. This paper analysed data from the Australian Orthopaedic Association National Joint Replacement Registry comparing survivorship of stems of offset 35.5mm or less with the standard stems of 37.5mm offset or greater. At seven years there was no significant difference in the Cumulative Percent Revision Rate in the short stems (3.4%, 95% CI 2.4-4.8%) compared with the standard length stems (3.5%, 95% CI 3.3-3.8%) despite its use in a greater proportion of potentially more difficult developmental dysplasia of the hip cases.

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.
