The biological and biomechanical comparison of two bulk bone graft techniques used in case of dysplastic acetabulum.

Background: The incorporation of bulk bone grafts in the replacement of dysplastic acetabulum is determined by the biological environment of the recipient site, the size of the contact surface, and the stability of the osteosynthesis used. Based on these, the present study compares the Harris acetabular plasty used routinely by us with the Radojević L-shaped graft technique.

Methods: For our measurements, we used 20 hemi-pelvises removed from 10 cadavers.
