Cementing Acetabular Liners Into Secure Cementless Shells for Polyethylene Wear Provides Durable Mid-term Fixation

摘要

BackgroundIn a previous experiment studying cementation of liners into cementless acetabular shells, placing grooves in the liner in a spider-web configuration created the greatest construct strength. Scoring shells without screw holes or other texturing helped prevent failure at the shell-cement interface. However, it was unclear whether these practices caused durable constructs in patients.
