We have compared prospectively the incidence of loosening of 20 femoral stems with a matt surface with that of 20 polished stems of an otherwise identical tapered, non-modular design of Exeter hip replacement. The stems were inserted using the same technique at operation and radiographs showed no difference in the adequacy of the cement mantle or of fixation. All the patients were reviewed regu...

This article studies Young Avestan forms in -āiš (formally instr.pl.m./n. of a-stems), nom.-acc.pl.f. ā-stems) and -īš nom.pl.f. ī-stems) that are used contexts where neuter nom.-acc.pl. / collective (a-stems) (consonantstems) expected. It is argued these -āiš, , secondarily created pluralizations original collectives reaction to the syntactic change according which their singular verbal concor...

Finite-element analysis was used to study the general differences in load-transfer mechanisms and stress patterns of cemented, fully ingrown, proximally ingrown, and smooth press-fitted femoral stems in total hip arthroplasty (THA). Identical stems were used for the noncemented configurations and a similar stem shape for the cemented configurations. In each model, bone properties and loading ch...
