The results suggest that by using a ceramic femoral head cocr fretting and corrosion from the modular head neck taper may be mitigated but not eliminated.
E polythelene with a 36 mm ceramic femoral head.
In this prospective study we examined 93 consecutive uncemented thrs in 80 patients implanted in our institution between 1986 and 1989 the mean age at the time of the operation was 51 2 years 28 65.
It combines the excellent material properties of alumina ceramics in terms of chemical and hydrothermal stability with extremely low wear superior mechanical strength and improved.
Biolox delta ceramic femoral head sizes 28mm 38mm are not recommended for use with a used stem trunnion.
Biolox delta is a high performance ceramic biocomposite material with the potential to be used in applications which were not previously possible using ceramics.

One hundred femoral head stem pairs were analyzed for evidence of fretting and corrosion using a visual scoring technique based on the severity and extent of fretting and corrosion damage observed at the taper.
20 years ago the average femoral head size was 22 mm.
Size is another important technical consideration.
Purpose of the study to determine the rate of polyethylene wear in hip arthroplasty depending on various factors and to evaluate a correlation of wear rate and motor activity of the patient.
Developed by sir john charnley as low friction arthroplasty total hip arthroplasty tha is one of the most successful procedures in medicine 1 2 consistent with autogenous low friction between living bone and articular cartilage charnley 3 4.
Recognized that reducing resistance to the movement of prosthetic femoral heads within acetabular cups would reduce surface wear and.
