AI Article Synopsis

  • Metallosis is a condition where metallic debris from failed joint prostheses infiltrates surrounding tissues and bone.
  • A 45-year-old man experienced severe metallosis and skin changes 17 years after receiving a modular prosthesis for osteosarcoma, worsened by a refusal to undergo recommended surgery after a car accident led to a breakage.
  • The authors emphasize the importance of timely revision surgery to prevent severe complications like metallosis when a prosthesis fracture occurs.

Article Abstract

Introduction: Metallosis is a condition characterized by an infiltration of periprosthetic soft tissues and bone by metallic debris resulting from wear or failure of joint arthroplasties.

Presentation Of Case: Authors describe a case of a 45-year-old man treated for an osteosarcoma of the distal femur with a modular prosthesis when he was 18 years old, he developed massive metallosis with skin dyspigmentation after 17 years. His medical\surgical history was remarkable for a left tumoral knee prosthesis implanted 21 years ago. Two years before revision, the patient had a car accident with a two-points prosthesis breakage and despite the surgeon's advice, the patient refused surgery. In two years, prosthesis malfunction caused a progressive catastrophic soft tissues infiltration of metallic debris.

Discussion And Conclusion: Authors suggest that if prosthesis fracture is detected, revision surgery should be attempted as earlier as possible.
