| The most commonly used prostheses are metal femoral components with plastic acetabular cups. |
| Distance from acetabular axis to anterior end of sacrum 30 mm. |
| The muscle volume has to go somewhere, so the circumference of the cup-shaped acetabulum has to increase, increasing the volume of the acetabular chamber. |
| Subsequent plain films and computed tomography confirmed satisfactory reduction with no acetabular fracture. |
| Offset acetabular and femoral instruments and low-profile reamers fit better through the smaller incision. |
| An x-ray is taken postoperatively to verify that the acetabulum is corrected and the acetabular fragment is secured with cortical screws. |
