Resumen (ES)
A seventy-six-year-old patient was seen at our
hospital, because he suffered a periprosthetic fracture 15
months after performing a metal-on-metal uncemmented
total hip arthroplasty. He had severe osteolysis and loosening
of the total hip components, with a lot of intraarticular fluid.
Histological examination of the periprosthetic tissues and biomechanical
study of the damage of the materials were done.
There were macrophages around the vessels with metal particles
inside. All of the intraoperative cultures were negative
for infection. This is an early loosening uncemmented total hip
arthroplasty due to osteolysis probably secondary to fluid
pressure.
