Figures
- Figure 1.
In the typical dual-mobility construct, a small central metal or ceramic head couples with a large polyethylene head inside the acetabular cup.
- Figure 2.
X-ray shows the dislocated and uncoupled polyethylene head in the soft tissue. The arrows surround the bubble sign of the polyethylene head apparent in the soft tissue.
- Figure 3.
Our patient's initial x-ray after dislocation. The properly coupled large polyethylene head can be seen as a shadow around the small femoral head.
- Figure 4.
Our patient's x-ray after the reduction attempt. The small femoral head is eccentric inside the acetabular cup. The arrows show the dissociated polyethylene femoral head in the soft tissue.
- Figure 5.
A: Coronal computed tomography (CT) image shows the polyethylene head dissociated and in the soft tissue. The arrows surround the polyethylene head. B: In a similar CT image in the axial plane, the arrows show the polyethylene head.
- Figure 6.
A: Intraoperative photograph of our patient. After slight dissection down, the polyethylene head was visualized and photographed. B: Our patient's dissociated dual-mobility prosthesis in the operating room after removal.
- Figure 7.
Postoperative x-ray shows the concentric reduction and proper alignment after revision dual-mobility implant.
