Dynamic recording fields were calculated for various head structures and head materials.
Standardization of surgical taper assembly is desirable for all head materials: taper assembly has been implicated in ceramic head fracture as well as in fretting and corrosion.
The electron accelerators operating above 10 MeV can result in the production of neutrons, mainly due to photo nuclear reaction (γ, n) induced by high energy photons in the accelerator head materials.
Different head materials are currently used.
A large range of datasets of head materials were provided in these materials studies.
This contour is easier to determine on the more radiopaque cobalt-chrome heads, but we found no statistically significant difference in precision between the head materials.
No statistically significant differences were identified regarding the use of acetabular liner and femoral head materials between patients tested before and after operation.
To confirm that any differences in DNA recovery observed were due to the higher drying rate and not differences in the swab materials, an experiment was performed at Eurofins Medigenomix GmbH, Ebersberg, Germany, to compare the influence of the different swab head materials on DNA release.
The aim of this study was to investigate a possible difference in wear patterns between 2 different head materials (cobalt-chrome and alumina) of the same size (28 mm) articulating on liners made of identical PE in the same type of acetabular shell.
Three months after sowing, when all spring standard varieties had headed, experimental materials were classified as either spring (ear emergence) or winter (no visible ear formation) types.
