In conclusion, based on our experimental and clinical material and analysis of failures, we recommend wire mesh reinforcement and bone graft for patients with mild to moderate protrusio. If the floor is strong but the pillars deficient, then the Eichler ring alone is the best implant. The combined system of wire mesh and Eichler ring should be used in cases of protrusion with a large deficiency of the acetabular floor and for protrusio with pillar weakness. Furthermore a bone graft should be used to reinforce the acetabular floor in addition to any prosthetic device.
