Breakage of Metal Shell in Total Hip Replacement using CLS Expansion Press-Fit Cup: A Case Report

ABSTRACT

Acetabular metal shell breakage is very rare after a total hip replacement. We encountered one case of metal shell breakage at approximately 8 years after the total hip replacement arthroplasty using a CLS expansion cup without a trauma history. Breakage of the metal shell was confirmed during revision surgery. We report this rare case with a review of the relevant literature.
