Fig. 5From: Is the construct stability of the acetabular cup affected by the acetabular screw configuration in bone defect models?Coronal lever-out test using Instron testing machine. A Jig was connected to the center of an acetabular cup, and the load was applied to a point 200Â mm distal from the center to record the results into moment-angular curves and establish the coronal lever-out strength (a, b)Back to article page
