The indication for operative treatment of displaced acetabular fractures is
widely accepted. The radiologic diagnostics consist of the a.p. pelvic vie
w and the oblique ala and obturator views. With the X-rays and the addition
al CT images the fracture is classified according to Letournel or to the AO
Classification into an A, B or C-type fracture. The appropriate surgical a
pproach is chosen depending on the classification and the site of the main
dislocation. Extended or combined approaches are only indicated for complex
or older fracture patterns. Osteosynthesis is performed either with small
fragment cortical screws in lag screw technique or with reconstruction plat
es. In about 80% of the cases an anatomical reduction of the joint is possi
ble as prerequisite for good functional results. First clinical trials with
computer- and/or CT-assisted procedures are promising. In future computer-
and robotics-based procedures will gain increased importance with reduced
patient morbidity and improved reconstruction of the joint surface.
