Data on file at biomet.
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.
The findings of this study support further study of the role of ceramic heads in potentially reducing femoral taper corrosion.
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 clinical impact of the associated corrosion debris from.
20 years ago the average femoral head size was 22 mm.
Biolox delta is a high performance ceramic biocomposite material with the potential to be used in applications which were not previously possible using ceramics.
Today the average size is 32 mm.
A new ceramic in orthopaedics.
Please consult the surgical technique and or package insert for proper use of the biolox delta option 40mm head.
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.
