Ceramic femoral head wear.

P biomet offers both the biolox delta and the biolox delta option ceramic femoral heads. Less wear more options without the risks even the best cobalt chrome and ceramic femoral heads come with the risks of wear or breakage. When a larger ball head is used in a wear couple it allows to obtain an increased range of motion and stability for the patient or to reduce the risk of subluxation. A larger sized femoral head is less likely to dislocate but will normally cause more wear.

He noted previously published studies have shown. 1 2 6 ceramic on ceramic articulation has the lowest wear rate among various articulations. Ceramtec is in the early stages of providing adapters to fit over a used trunion thus providing a defect free taper for a new ceramic head and the ability to retain a well fixed femoral component. The biolox delta option ceramic head features a titanium neck sleeve designed to allow surgeons to utilize a ceramic head in either primary or.

The retrieval analysis of the fractured alumina matrix composite ceramic head revealed an extremely wear resistant surface. Trousdale md corrosion is the real issue when it comes to choosing between a ceramic and a cobalt chrome femoral head. Analyzing the clinical experience of more than 20 years it can be concluded that all the improvements have produced reliable ceramic femoral heads. Oxinium technology combines the strength of metal with the smoothness of ceramic to offer the benefits of both without the risks.

But with oxinium femoral heads those risks are history. The biolox delta component is a traditional one piece ceramic head indicated for primary hip arthroplasty only. Low wear with multiple liner options. With the very low rate of wear associated with ceramic implants particularly ceramic on ceramic the surgeon is free to use a larger head and thus reduce the risk of dislocation.

Our results are slightly lower than previously reported wear of ceramic and metal heads on hxlpe bearings which has been in the range of 0 012 0 067 mm y 22 29 32. After 3 months and up to 5 years there was very little penetration of the femoral head into the liner in both groups. 1 however there is a concern about ceramic head fracture therefore ceramic head with polyethylene liner has been introduced. A ceramic cup can not incorporate.

Larger ceramic ball heads. The wear rate of ceramic on ceramic is virtually zero 0 07 μm year and even the few particles generated are completely inert. According to robert t. Ceramic hip replacement disadvantages.

An alumina ceramic femoral head is a good bearing material because it is the smoothest material and therefore possesses the lowest wear properties low abrasive linear and volumetric wear.
