Alumina Biocompatibility

Journal of Long-Term Effects of Medical Implants, 2018
Alumina (Al2O3) ceramic is widely used for medical devices and its biocompatibility is well known and is reported in articles and textbooks. However, finding proof of this assertion gathered over more than 40 years can be challenging. We performed a literature review about alumina biocompatibility to compile data from the literature.

Alumina-Alumina and Alumina-Polyethylene Total Hip Prostheses

2004
By the late 1960s, the Charnley hip implant system with a metallic femoral stem and an ultrahigh molecular weight polyethylene (UHMWPE) acetabular component was the primary design for successful total hip arthroplasty (THA). Many of today’s concerns regarding the Charnley system were recognized as early as 1970.

ALUMINA-ON-ALUMINA TOTAL HIP ARTHROPLASTY

The Journal of Bone and Joint Surgery-American Volume, 2005
Ceramic-on-ceramic couplings are attractive alternative bearing surfaces that have been reported to eliminate or reduce problems related to polyethylene wear debris. Disappointing experiences with alumina ceramic bearings in the past have led to many improvements in the manufacture and design of ceramic implants. The purpose of the present study was to

Individual Alumina Nanotubes

Angewandte Chemie, 2001
Anodization of aluminum with H2 SO4 on an Si substrate results in the formation of individual alumina nanotubes (ANTs). The picture shows an ANT with a length of 650 nm and internal and external diameters of 12 and 35 nm, respectively. Detailed studies by transmission electron microscopy revealed that the ANTs are completely detached cells of the ...
