Survivorship of Primary Total Hip Replacement Using Short-Stem Variants of the Exeter V40 Femoral Stem: Median 5-Year Follow-Up Study
Description
In this presentation, Liam Yapp discusses a study comparing the mid-term survivorship of three short stem variants of the Exeter V40 femoral stem in primary total hip replacements. He begins by thanking his coauthors and acknowledging the credibility of the Exeter V40 as a market leader in the UK with a strong long-term survivorship record. The study aims to fill the gap in existing literature regarding short stem variants due to limited evidence on outcomes.
The research is a retrospective case control study utilizing an institutional implant registry. The study group consists of patients who received a short stem variant, while a control group was established using patients who received a standard Exeter V40 stem in 2011. Yapp discusses the demographic differences, noting that the short stem cohort primarily consisted of younger, predominantly female patients. The overall survivorship rates were analyzed using Kaplan-Meier survivorship estimates and Cox proportional hazards regression.
Results indicated no significant differences in overall survivorship between the short and standard stem cohorts after five years, despite high censorship rates affecting long-term data. Further breakdown into specific short stem variants also showed no notable differences in revision rates. The study concludes that short stem variants demonstrate satisfactory mid-term survivorship compared to standard stems, although the authors caution about possible higher revision rates in certain subgroups based on findings from external registries. Yapp acknowledges the study's limitations, including relatively short follow-up duration and lack of radiographic analysis, suggesting that future research may be needed to confirm these findings as more data becomes available. He ends the presentation by reiterating the study's key conclusions and inviting applause.
