Abstract
Two BMJ observational studies report increased survival of
patients after metal-on-metal resurfacing versus cemented or
uncemented total hip replacement.1 2 We considered the potential
usefulness of these new estimates for lifetime cost effectiveness
models, which necessitate extrapolation beyond observed data.3
Cost effectiveness models have assumed similar mortality
irrespective of implanted device.4-6
McMinn and colleagues examined men under 55 years who
received Birmingham hip resurfacing or cemented or
uncemented hip replacements (mean age ~48 years).1 Kendal
and colleagues compared resurfacing with cemented and
uncemented proceduresin propensity matched groupsfollowed
for 10 years (mean age 57-59 years; 55-59% men).2 McMinn
and colleagues’ estimated six year survival after resurfacing
was 0.995; survival in those who underwent cemented and
uncemented procedures were 0.018 and 0.013 worse,
respectively.
