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

INTRODUCTION: Common causes of revision total hip arthroplasty (THA) are component wear, implant loosening, dislocation, and infection. CASE REPORT: An 84-year-old female patient is presented with an unusual pattern of hip dislocation due to structural failure of the cup construct and excessive comp...

description INTRODUCTION: Common causes of revision total hip arthroplasty (THA) are component wear, implant loosening, dislocation, and infection. CASE REPORT: An 84-year-old female patient is presented with an unusual pattern of hip dislocation due to structural failure of the cup construct and excessive component wear. CONCLUSION: Component wear of THA can drive to catastrophic failure of the implants and significant soft tissue metallosis. Early diagnosis allows interventions even in those hips that are asymptomatic. 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.
