Patients may require more revisions of their hip arthrodesis during their lifetime due to the early failure of the Durom Cup
Patients who experience the failure of a Durom Cup require a "revision" surgical procedure in which the cup is removed and replaced with a different design. Instead of the Durom Cup lasting its predicted life span of 15-20 years, the revision procedure is often performed at 3-5 years after it was originally implanted. Since revisions are expected to last 10-15 years, such patients will therefore have to undergo more revision procedures during their lifetime because the Durom Cup failed prematurely.
For example, assume a woman patient who was only 52 years old at the time of her primary hip surgery. Assuming an 80 year life expectancy, had that patient's Durom Cup hip replacement lasted the expected duration of 20 years, she would have been subjected to only one hip revision surgery during her life expectancy. However, since her primary hip implant lasted less than five years, that patient will likely be subjected to 2 or even 3 revision hip surgeries in her lifetime.
In addition to the risks of surgery, including but not limited to infection, embolisms and anesthetic complications, revision total hip surgeries generally have poorer functional, patient satisfaction and quality of life outcomes. The combination of these hazards and exposure make the Durom Cup device unreasonably dangerous and unsuitable for its intended purpose.
