Pre-operative (A) and post-operative (B) X-rays of the pelvis and left hip demonstrating a chronic pelvic discontinuity of the left hemi-pelvis that required revision with an uncemented hemispherical shell supported by porous metal augments unitized to the shell. A Dome technique was used by placing augments into the massive anterosuperior acetabular defect. Acetabular distraction was utilized to ensure a large enough cup was implanted and to enhance compression across the discontinuity.
