Intraoperatively, there was a longer separation of the spacer and shaft parts and acute tears in the head part, probably due to the dislocation mechanism (Figures 3 and 4).

The prosthetic head dislocated into the ventral elbow joint capsule, leading to joint blockage (Figure 5).

Histopathologically, there was an aseptic inflammatory response to foreign bodies with activated epithelial cells and multinucleated giant cells with intracytoplasmic foreign material (Figures 6 and 7).
Histopathology. HE staining, 100x maginification, aseptic inflammatory response to foreign bodies with activated epithelial cells and multinucleated giant cells with intracytoplasmic foreign material (green arrow).
