case_images: A left hip anteroposterior x-ray in a 75-year-old female
  patient with groin pain. No acetabular abnormalities visible. Lateral
  migration of the hip screw nails.

case_images: There were no signs of acetabular fracture on this AP projection (Fig. 1).
case_images: X-ray of the same patient two months later. The medially-migrated
  femoral head, with an acetabular transverse fracture, is
  evident.

case_images: A cemented total hip replacement was performed, with no osteosynthesis or bone graft of the acetabular fracture (Fig. 3); bone and soft tissue samples obtained intraopera-tively were negative for bacteriological cultures.
case_images: Five year follow-up.

case_images: Anteroposterior pelvis x-ray of an 80-year-old female
  patient. Normal osteosynthesis of a left perthrocanteric fracture at
  2-year follow-up with a screw-nail device can be seen.

case_images: No abnormalities were seen in the AP pelvis X-ray (Fig. 6). Careful examination of the initial X-rays revealed that the ilio-ischial line was interrupted at the greater sciatic notch (Fig. 6).
case_images: Anteroposterior pelvis X-ray of the same patient, one
  month later. A left acetabular transverse fracture is evident, with
  mild medial displacement of the femoral head.

case_images: At the one-month evaluation she still had groin and thigh pain, and a left transverse acetabular fracture with mild medial protrusion of the femoral head was observed radiologically (Fig. 7 - arrow-).
case_images: Anteroposterior pelvis X-ray two months later. Fracture
  consolidation.

case_images: A subsequent x-ray, 2 months later, showed that the fracture had probably healed (Fig. 8).
case_images: PMC3528042_03
case_images: No fracture was found, although thickening of both
  iliopubic rami and ischia could be seen, resembling the prior stage
  of a stress fracture.

case_images: Thickening of both iliopubic rami and ischia was found, as a previous stage of a stress fracture (Fig. 9).
case_images: Anteroposterior x-ray of an 83-year-old patient with groin
  pain. Non-union of the right anterior acetabular column and
  ischium can be seen. An apparently healed fracture in the left
  anterior acetabular column is also visible.

case_images: As the pain increased during the following weeks, another X-ray was taken two months later (Fig. 10).
case_images: Anteroposterior x-ray of the same patient at one year
  follow-up. Non-union is not resolved.

case_images: Home bed rest without traction for two weeks followed by walking with weight bearing was prescribed, and during follow-up a non-union of the fractures became evident (Fig. 11).
