Two days following admission, the patient underwent a cemented hemiarthroplasty via the posterior approach to the hip without complication (Figure 2).
AP pelvis radiograph obtained 2 weeks postop demonstrating joint space narrowing and medialization of femoral component.

Radiographs (Figure 3) and computed tomography (CT) scan demonstrated increased medialization of the femoral component into the acetabulum without evidence of loosening or hardware complications.
AP pelvis radiograph at 6 weeks postop demonstrating fracture at the medial acetabular wall with superomedial migration of the femoral head, protrusio acetabuli, and no evidence of femoral component loosening.

Radiographs (Figure 4) and CT again demonstrated increased medialization of the femoral head, now with a fracture of the medial wall of the acetabulum.
AP pelvis radiograph obtained immediately following conversion to right total hip arthroplasty.

She underwent conversion to a right total hip arthroplasty the next day (Figure 5) via a posterior approach.
AP pelvis radiograph obtained 2 weeks after revision to total hip arthroplasty. No evidence of component loosening. Fracture line without displacement.
