项目摘要
DESCRIPTION (Adapted from the Applicant's Abstract): Aseptic loosening
continues to be a problem with total hip replacements. In cemented total
hip replacement, mechanically induced loosening most often initiates at the
stem-cement or cement-bone interface. And while it is widely accepted that
a strong bone is desirable at the cement-bone interface, the optimal
cement-metal interface is disputed for cemented femoral components. A
research program is proposed to investigate: 1) the specific mechanical
conditions under which the femoral stem-cement and cement-bone interfaces
fail; 2) the manner in which interface failure contributes to mechanical
loosening of cemented femoral hip components; and 3) the use of this
information to "optimize" the locations and extent of stem-cement bonding to
reduce the risk of implant failure. Here, "bonding" is used to describe any
enhanced stem-cement interface (mechanically roughened or PMMA precoated),
as compared to a smooth unbonded interface. It is the hypothesis of this
work that the manner and extent of bonding of the stem-cement interface
affects the overall failure (loosening) of the implant. It is further
hypothesized that some "optimum" configuration, consisting of regions where
the stem is bonded, and regions where the stem is unbonded, will result in a
significant increase in the long-term performance of the implant.
