An Unusual Central Dislocation of a Total Hip Arthroplasty Due to Severe Wear of a Ceramic on Cross-linked Polyethylene Bearing Coupling - A Case Report.

In the case of a THA dislocation, a thorough imaging control is necessary to reveal structural failure and avoid repetitive and aggressive manipulations for reduction.
