Pelvic fractures.

Stabilization of unstable pelvic fracture is warranted to relieve pain and to reduce bleeding. A trapezoid frame external fixation is suggested for reduction and retention of such fractures. Some controversy exists concerning the sources of bleeding and the measures for control. On the one hand, bleeding arises from fractures of the cancellous bone. On the other hand, blood vessels may be torn by the fracture. Massive bleeding is common which requires a good blood bank service. The complications of pelvic fracture consist bleeding, nervous and urological injuries.
