A combination prospective and retrospective review has been performed to gather
clinical data on the use of polycarbonate-urethane (PCU) as an articulating bearing
material inside a cobalt-chrome (Co-Cr) acetabular shell. First implanted in
December 2007, this product has now been used in humans in three countries:
Germany, Spain, and Italy. As of January 2010, this cobalt-chrome shell and PCU
liner has been implanted into 85 total hip patients by 11 surgeons. A total of 47 were
prospectively followed and 38 retrospectively followed. The indications for use were
in 78 cases of osteoarthritis, 5 cases of femoral neck fracture, 1 case of idiopathic
pathology, and 1 revision case. One patient had an occasional squeak and 1 patient
died of mesenteric ischemia 1 month after surgery. The follow-up times were as
follows: 17 patients at 6 months or less, 47 patients at 12 months, and 21 at 24
months, for an average follow-up time of 14 months. None of the cases has had a
dislocation, revision, dislodgement, or infection. A detailed review of the clinical data
of these patients shows that PCU liner inserted into a Co-Cr acetabular shell is as
safe and effective as other commonly used acetabular shells in other total hip
systems currently available. No new or unintended adverse or device related events
were discovered with the clinical use of PCU in a Co-Cr acetabular shell.
