Rebuilding the wall helps recreate a stable socket that can accept and transfer joint loads through the hip. When disease, trauma, or revision surgery has removed supporting bone, reconstruction provides a structural foundation for fixation of the acetabular component. This can improve joint stability while supporting functional recovery and longer-term reconstruction.
The reconstruction is secured to the remaining host bone, allowing the repaired region and the revision acetabular component to function as a connected construct. This relationship helps distribute loads through available bone rather than relying only on the damaged area. Stable fixation is particularly important when revision surgery has produced substantial acetabular bone loss.
A shaped bone graft can restore missing structure while providing a pathway for biological healing and incorporation. A porous metal augment or another implant can instead supply structural support within the reconstruction. Each option is integrated with remaining host bone and the revision acetabular component to address the defect and help re-establish durable fixation.
Re-establishing the hip center helps place the reconstructed socket in a mechanically appropriate position for the joint. Along with restoring the wall, this supports more effective load transfer and contributes to hip stability. The goal is therefore not only to fill a defect, but also to recreate the spatial and structural conditions needed for durable reconstruction.
The surgeon first prepares the acetabular defect and assesses the remaining host bone. A bone graft, porous metal augment, or other implant is then shaped or positioned to reconstruct the missing wall. The reconstruction is fixed to the host bone and incorporated into a revision acetabular component, creating a stabilized construct for subsequent healing.
This approach is used most notably during complex total hip arthroplasty revisions when acetabular bone loss compromises the socket. It also applies to acetabular fractures that disrupt the bony wall. In both settings, the technique addresses structural deficiency while aiming to restore hip stability, the hip center, load transfer, and durable component fixation.
