case_images: Plain radiograph revealed significant ceramic flaking (Figure 1A), prompting the recommendation for right hip prosthesis revision. Follow-up x-rays confirmed well-positioned acetabular and femoral prostheses with normal anteversion and abduction angles, as well as proper fit and stability, resulting in a satisfactory surgical outcome (Figure 1B).

case_images: During surgery, a fractured femoral head and surrounding bone spurs were discovered after a "T"-shaped incision in the joint Subsequently, we conducted proactive surgical debridement, cleared the proliferative tissues, and removed the fragmented femoral head prosthesis (Figure 2A). Aesculap ceramic head. After testing the new 28 mm ceramic head, it was inserted, and the tightness was satisfactory (Figure 2B).

case_images: Plain radiographs showed many small ceramic fragments flaking around the hip joint (Figure 3A). Postoperative radiographs showed well-positioned acetabular and femoral prostheses with appropriate anteversion and abduction angles, and no signs of loosening. (Figure 3B).

case_images: The presence of a significant amount of black wear debris and turbid fluid accumulation in the surrounding area suggested a more chronic process than initially apparent (Figure 4A). Subsequently, we completely excised the joint capsule and the tissues stained black due to the ceramic wear debris (Figure 4B). There were many traces of metal on the surface of the ceramic head due to prolonged friction with the metal cup (Figure 4C).
