THE 7–11 YEAR FOLLOW UP OF THE EXETER FEMORAL STEM – THE EXPERIENCE IN DERBY

Abstract

We reviewed 158 hip replacements performed using the Exeter® stem between 1992 and 1996. The operations were performed using third generation cementation and the majority using medium viscosity Simplex cement via a posterior approach. Per-operative complications [shaft fracture etc] were not seen.

Using stem revision as an endpoint, only one stem has been revised [0.6%] for aseptic loosening, and one for sepsis. Aseptic asymptomatic loosening was observed in a further 4 patients [2.5%]. Stem subsidence was seen in the majority [81%], but none greater than 3mm [mean 1.4mm]. Other complications were rare.

This medium term review confirms that the Exeter® stem is a prosthesis with excellent results. This is one of the first series published outside Exeter to confirm their reported results.
