case_images: Open posterior dislocation of the right knee with protruding femoral condyle through the wound (a). The reduction of dislocated hip was done using two trans-fixating Steinman pins inserted in the distal femur (b).

case_images: fig1-2050313X241233199
case_images: The distal femur was protruding through the wound and a fracture of the patella was visible (Figure 1(a)). To do so, two trans-fixiating Steinman pins were inserted into the femoral condyles (Figure 1(b)).
case_images: Standard X-ray showing a right hip dislocation (a) and an ipsilateral knee dislocation with a patella fracture (b).

case_images: On the left side (Figure 2), displaced mid-shaft femur and tibia fractures were noted realizing the so-called floating knee.
case_images: Postoperative X-ray of the knee (a and b) showing an acceptable reduction of the knee dislocation. CT scan of the hip (c) showing a congruent hip joint with undisplaced femoral head fracture.

case_images: fig3-2050313X241233199
case_images: Pelvis CT scan showed a congruent hip joint with a minimally displaced posterior wall fracture and a Pipkin type I undisplaced femoral head fracture (Figure 3).
case_images: Clinical results at the last follow-up.

case_images: fig4-2050313X241233199
case_images: At 18 month follow-up, the right knee was stiff at a fixed 5  flexion contracture (Figure 4).
case_images: Standard X-ray of the knee at the last follow-up (a and b): a bone bridge joining the medial femoral and tibial condyle. No avascular necrosis of the femoral head was seen on the X-ray of the pelvis (c).

case_images: The right hip, however, was fully mobile with occasional pain and no signs of avascular necrosis (AVN) (Figure 5).
