There are two components of the hip joint. The aim of this study was to determine the wear of large size 36 mm highly cross linked polyethylene inserts against ceramic and cobalt chrome femoral heads using a physiological hip simulator and test conditions. The use of ceramic heads in conjunction with highly cross linked polyethylene is supported in the literature 4 5 and relies upon the principles of increased scratch resistance increased. The latest generation of ceramic on polyethylene biolox delta on highly cross linked polyethylene has shown an excellent linear wear rate 0 006 mm yr which is much lower than previously found wear rates for cobalt chrome on highly cross linked polyethylene 0 011 mm yr.

8 2 or a combination thereof and b the metal or ceramic head attached to a metal stem that is inserted into the femur to provide stability to the prosthesis. Biolox forte and biolox delta ball heads and cup inserts can be combined with ceramic components from the biolox family of products as well as with inserts made from conventional and highly cross linked polyethylene.
