Abstract

Pseudotumors are a rare but important complication occurring with all types of hip replacements.

The true prevalence of pseudotumors is debated.

Potential causes of pseudotumors may include foreign-body reaction, hypersensitivity, and wear debris.

The conduct of clinical trials on the incidence, causes, and treatments of pseudotumors has been inadequate as few investigators have used a randomized controlled design to compare various implant types.
