Acetabular fracture can result in severe limitation of the motion of the hip joint, which supports totalweight of human body. Beause of different methods of surgical approach a ccording to fracture type, preciseinterpretation of X-ray films of acetabular fracture is required. We reviewed 38 cases of simple X-ray filmsshowing acetabular fracture. The results were as follows: 1. Almomst 60% of the cases-were in their 2nd and 3rddecades. 2. Twenty cases were male, and 18 cases were female. 3. The most common cause of the injury was trafficaccident(33 cases, 86.8%), followed by fall down (4 ases, 10.5%) and slip down(1 case, 2.7%). 4. Elementaryfractures were 21 cases(55.3%) and associated fractures were 17 cases(44.7%). 5. Among elementary fractures,posterior wall fractures were 9 cases(23.7%), followed by anterior column fractures(8 ases, 21.1%), anterior wallfractures(4 cases, 10.5%). 6. Among associated fractures, T-shaped fractures were 8 cases(21.1%), followed by bothcolumn fractures(6 cases, 15.8%), anterior and hemitransverse fractures(3 cases, 7.8%). 7. Other pelvic bonefractures associated with the acetabular fracture were as follows: farcture of contralateral pubic rami(6 ases,15.8%) contralateral iliac bone (1 case, 2.6%) and ipsilateral iliac bone (1 case, 2.6%). 8. Injuries of otherorgans adjacent to the acetabulum were as follows: rupture of the bladder (3 cases, 7.9%), urethra(2 cases, 5.3%)and uterus (1 cases, 2.6%).
