protrusio acetabuli in RA

This is 36 year old Doctor with RA on long term steroids. Presented with pain in hip as well as knee.

Why do we wait to complicate reconstruction?

Problems

1. Severe Osteoporosis

2.Huge cavitatory acetabulum with deficient medial and anterior wall

Young patient

Any comments on Options for acetabular reconstruction.

 We used a Cone prosthesis and a wagner uncemented cage with ceramic on poly bearing.

 A peripheral fitting cup was an option but due to the osteopenia, we opted for  a cage which came in 2 sizes. I understand Zimmer has withdrawn both these products from Sulzer.
