case_images: The initial anteroposterior (AP) pelvic X-ray (1A) and Pelvic CT images showing posterior dislocation and Pipkin II fracture of the femoral head, with a large fragment remaining in the acetabulum (1B: frontal view; 1C: sagittal view; 1D: axial view; 1E: three-dimensional reconstruction).

case_images: Pelvic X-rays revealed fracture of the right femoral head with posterior hip dislocation but without any associated acetabular fracture (Fig. 1A). A cephalic fragment remained in the glenoid cavity, but a distal fragment had ascended and migrated posteriorly (Fig. 1B-E).
case_images: Immediate postoperative X-rays of the right hip after total hip arthroplasty (2A: AP view; 2B: profile view), and X-rays taken at the 12-month follow-up showing osseointegration without loosening (C: AP view; D: profile view).

case_images: We placed an uncemented dual mobility cup (Novae Sunfit  size 51 [Serf  ]) and an uncemented Corail  KHO size 11 stem (Depuy-Synthes ) with a ceramic head of diameter 28 mm + 5 (Fig. 2A, B). X-rays revealed good implant osseointegration without any signs of early loosening (Fig. 2C, D).
