Bleeding from pelvic injuries
Pelvic injuries in Rugby are extremely rare and are more recognised in motor vehicle accidents. It is unlikely you will come across one due to the level of protection caused by the strong bony pelvis. They can be a significant cause of blood loss, however, due to the large number of veins in the pelvis as they group together from the legs and sharp pieces of bone from a pelvic fracture.
It is important not to cause unnecessary movement of the pelvis if you suspect it is injured in any way. This could cause further bleeding and increase pain. Remember that an open airway and MILS are the most important things to consider.
