In 1978, Elite identified polyethylene particles as the prime reason for disastrous sub-interface osteolysis. According to a technical paper, considering the mechanical point of view, the HDPE's radiation crosslinking shows a distinctive method for coping up the constraints in the orthopedic applications of this polymer. In one of the registered clinical follow-up of 650 cases carried out between 1977 and 1982, 56 cases out of 64 eligible ones were with no measurable wear. The rest of the cases reported total wear within a range of 1.0 - 4.0mm. Cup sizes are in the range 46mm to 62mm having inner articulating diameters of Æ28mm and Æ32mm. Oxidation is prevented by the rosslinked UHMWPE due to the strengthened articulating surface. Surface crosslinking is linked with improved visco-elastic behaviour and helps in getting rid of wear-induced osteolysis.
