THE TANTALUM CUP IN REVISION SURGERY: FIRST EXPERIENCES



Abstract

The main problem in revision hip surgery is the loss of bone, expression of the reactive phenomena to the granulation tissues secondary to debris production. The choice of surgical system and strategy is related to the bony loss.

The tantalum, due to its elevated porosity and microarchitecture and elasticities similar to trabecular bone, facilitates the periprosthetic osteointegration, so to be considered particularly indicated in acetabular revisions.

The Authors present clinical and radiological results of a two years experience with tantalum hemispheric cup, emphasizing its versatily, with possible choice between a model with reinforce net-like function with a cemented polyethylenic component and other with standard modular inlay.

In case of serious bone-loss bone banking graft has been used (except in septic mobilization, although a two-stage proedure with the use of temporary antibiotic-impregnated spacer) and two or more screws for additional fixator.
