[The morse taper junction in modular revision hip replacement].

Morse taper junctions of modular hip revision replacements are predilection sites for fretting, crevice corrosion, dissociation and breakage of the components. In this report we present the results of a retrieval analysis of a morse taper junction of a MRP-titanium modular revision replacement (MRP-Titanium, Peter Brehm GmbH, Weisendorf, Germany) after 11.5 years of in vivo use. In the context of this case report the significance of morse taper junctions in modular hip revision replacement under consideration of the current literature is also discussed.
