[Detection of occult fractures of the pelvic bones by roentgen computed tomography]

The informational value of C.T. concerning pelvic fractures is presented. Not all injuries to the hip joint and to the os sacrum can be seen on standard a.p.-projections, oblique views, special projections or conventional tomography. 17 typical examples have been selected from young patients with multiple injuries. C.T.-findings concerning fractures of the hip joint, of the os sacrum and of hidden pelvic fractures are described. Emphasis is placed on careful radiological analysis of fractures with special regard to the planning of conservative or operative treatment and also on the later functional results following fractures of the hip joint.
