Abstract
The effect of cyclic loading on the torsional stiffness of a polished double tapered femoral stem was investigated in vitro. Initial torsional stability was compared to torsional stability following cyclic loading. Stems were removed from the cement mantle and reinserted without the use of additional cement. Torsional stability was measured following reinsertion and following further cyclic loading.
Subsidence of the stem was observed. No difference in torsional stiffness was observed during loading. No difference between the stiffness prior to extraction and following reinsertion was observed.
Torsional stiffness of an Exeter stem does not decrease following axial subsidence under cyclic loading. Stability is retained following reinsertion into the original cement mantle. Debonding of the Exeter stem is not associated with rotational instability of the implant.

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.
