The author argues that the excess mortality observed with cemented total hip replacement in a previous study is likely due to case mix selection rather than fat embolism.
McMinn and colleagues’ conclusion that cemented total hip replacement increases the risk of death compared with uncemented hip replacement and hip resurfacing through an increased risk of fat embolism is misleading.1 Their paper shows a late apparent difference in mortality, but not an increased risk of death at 30 days, as would be expected if fat embolism had been …
