Acetabular fractures in the elderly: an easily missed diagnosis.

Two case reports of low-energy acetabular fractures in elderly people are presented. Both fractures were initially missed because standard hip radiographs were interpreted to be normal. Furthermore, the clinical findings were not strong enough to give the impression of a hip joint fracture. If there is pain in the hip region after a fall, in combination with the absence of clinical findings, appropriate radiographs should be taken to look for acetabular trauma.
