![]() The amount of trabecular bone with high stress was strongly negatively correlated with both cement volume and contact between the cement and cortex (r = -0.85 and -0.84, p implant-cortex distance. Correlation analysis was completed across all specimens for pairs of morphological and mechanical variables. Axial loading was applied to the implant of each model and stress distributions were characterized. Bone volume fraction, glenoid width, implant-cortex distance, cement volume, cement-cortex contact, and cement-bone interface area were measured. Specimens were imaged by micro-CT, and subject-specific finite element models were developed. Eight glenoid cadavers were implanted with a cemented central peg implant. Utilizing high resolution finite element analysis of a series of implanted cadaver glenoids, the objective of this study was to quantify relationships between construct morphology and resulting mechanical stresses in cement and trabeculae. ![]() ![]() Wee, Hwabok Armstrong, April D Flint, Wesley W Kunselman, Allen R Lewis, Gregory SĪseptic loosening of cemented joint replacements is a complex biological and mechanical process, and remains a clinical concern especially in patients with poor bone quality.
