Complications of Cages and Their Avoidance
There is a high incidence of complications associated with the use of cages. This is partly because of the complexity of the reconstruction requiring a cage, but also because of the biomechanical and biomaterial qualities of cages.
Recently, we reviewed our complications associated with the use of the cage [3]. Sixty-one cases with an average follow-up of 4.6 years were reviewed. These were complex acetabular revisions with 48 of 61 cases requiring a structural allograft, whereas the remainder
Trabecular Metal Cup Cage Concept
Our results reflect problems more with the protective cage than the bone graft. The current generation of cages do not provide biologic fixation, and loosening or breakage of the cage occurs eventually.
Trabecular metal acetabular implants, because of their porous nature, have the potential to provide a better environment for biologic fixation against host bone when limited host bone is available. The porous nature of trabecular metal also may provide a more favorable environment for the
