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.
E polythelene with a 36 mm ceramic femoral head.
Today the average size is 32 mm.
The clinical impact of the associated corrosion debris from.
Please consult the surgical technique and or package insert for proper use of the biolox delta option 40mm head.
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 is a high performance ceramic biocomposite material with the potential to be used in applications which were not previously possible using ceramics.
Learn about the long term durability of zimmer longevity highly crosslinked polyethylene hip implants.
Size is another important technical consideration.
The findings of this study support further study of the role of ceramic heads in potentially reducing femoral taper corrosion.
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.
20 years ago the average femoral head size was 22 mm.
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.

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.
Biolox delta ceramic femoral head sizes 28mm 38mm are not recommended for use with a used stem trunnion.
Recognized that reducing resistance to the movement of prosthetic femoral heads within acetabular cups would reduce surface wear and.
