Wright Profemur is a medical hip implant device that has been manufactured and sold in the United States since 2001. In 2009, due to the modular necks breaking in half, Wright changed the composition of the modular necks from titanium to Cobalt/Chromium. Since the change, thousands of patients across the country have had this device implanted into their bodies. But Profemur devices are prone to corrosion at the modular neck and femoral stem junction, which may cause patients to suffer severe health issues.
