2. AP radiograph of a similar posterior wall fracture with obvious
impaction. The arrows demonstrate the impacted articular
surface as visualized on the AP radiograph due to its tangency
to the beam.
3. A P radiograph of a similar posterior wall fracture with obvious
impaction. The arrows demonstrate the impacted articular
surface as visualized on the A P radiograph due to its tangency
to the beam.
6. CT scan at the level of the roof, demonstrating impaction
of the roof when the femoral head posteriorly subluxated.
7. CT scan at the level of the fovea, demonstrating
impaction and displacement of the posterior wall.
8. POSTERIOR WALL
CT scan at the level of the fovea, demonstrating
impaction and displacement of the posterior wall.
IMPACTION
9. HEAD FOOT
Standard dissection, as previously shown, with the patient in the
prone position. In this figure, the head is to the left and the feet
are to the right. The impaction is readily evident within the
posterior column upon exposure of the joint.
10. POSTERIOR COLUMN
HEAD FOOT
Standard dissection, as previously shown, with the patient in the
prone position. In this figure, the head is to the left and the feet
are to the right. The impaction is readily evident within the
posterior column upon exposure of the joint.
11. IMPACTED ARTICULAR SURFACE
FEMORAL HEAD
A closeup view of the impacted articular surface and the femoral head.
12. The reduction of the articular surface is performed using the femoral head
as a template. The picture on the left also demonstrates the defect in
cancellous bone between the intact posterior column and the now-reduced
articular segment. The image on the right is the same view after the defect
is filled with cancellous graft taken from the greater trochanter.
16. The above images show representative views after
fixation of the fracture with buttress plating.

19. AP, obturator and iliac oblique views of the fracture
after reduction. Note on the obturator oblique view
the area of trochanteric bone that was taken.
