| Porous coatings on the femoral stem and acetabular cup were developed in an attempt to create bone ingrowth and biological fixation. |
| We investigated the results of combined acetabular fractures that were treated through the extensile triradiate approach in this study. |
| Trial acetabular sizers are placed in the cavity to further assist with shell size determination. |
| 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. |
| An x-ray is taken postoperatively to verify that the acetabulum is corrected and the acetabular fragment is secured with cortical screws. |
| Progressive disease can produce acetabular changes, such as early triradiate closure, bicompartmentilization, and ischium varum. |
