Careful evaluation of the postoperative radiograph demonstrates:
- Reduction and fixation of the SI joint fracture dislocation. The intercalary fragment of the sciatic buttress is reduced and fixed to reconstruct the intact ilium.
- The iliac crest has been reduced and fixed to the intact ilium by plate osteosynthesis.
- The anterior column fragment has been fixed to the reconstructed intact ilium with two 160 mm anterior to posterior screws in the iliac corridor.
- The posterior column has been reduced to the anterior column with anatomic restoration of the radiological roof. A lag screw has been placed across this fracture line from anterior to posterior.
- The posterior column reduction has been stabilized with independent posterior column interfragmentary screws.
- The posterior column plate has been applied. Note the position of the distal screw down the ischium.
- This surgeon utilized a trochanteric osteotomy option to perform the extended iliofemoral exposure. Two screws stabilize the trochanteric fragment.
- All screws are extraarticular (though this evaluation requires the obturator and the iliac oblique views).
