Fatty bone marrow microemboli in the joint pseudocapsule after implantation of total hip joint endoprosthesis

The histological findings seen in a total hip joint endoprosthesis pseudocapsule are presented. The patient underwent reoperation after total hip replacement performed 18 years previously. Abundant fibrosis with a necrotic area, sheets of histiocytes, and numerous foreign-body-type giant cells with bone cement particles phagocytized in their cytoplasms were observed. Multiple fatty bone marrow microemboli occluding the microvessels were seen. This feature should be considered being responsable for the pathogenesis of the necrotic area in the endoprosthesis pseudocapsule.
