Article about Metal Allergies by Dr. De Smet and Pat Campbell
Dr. De Smet writes that although very rare, a reaction can occur after a BHR hip replacement. The following is a story about a problem that Dr. De Smet thinks is associated with a metal sensitivity in a BHR.

While metal allergies are indeed rare, they can be (or have the effect of being) all too real….. My wife is 31 yrs old and had her right hip resurfaced 2 years ago by Dr. De Smet (she originally broke her hip around 10 years, developed AVN, had an osteotomy 7 years ago, developed arthritis, which ultimately led us to Ghent – can’t say enough about
Metal-metal bearings have advantages for active patients because their wear resistance is much greater than that of polyethylene, they do not fracture and they perform better with larger diameter balls. It has been known for three decades that the serum and urine levels of cobalt and chromium (the main elements in a metal-metal hip bearing) are increased in patients with a metal-metal bearing. The health impact of such ion levels has not been established and continues to be debated. Trace element analysis requires very sensitive equipment since the levels are in parts per billion (ppb). Absent some environmental exposure, serum and urine levels of cobalt and chromium are effectively zero in people with no metallic
