Unstable type B and type C fractures.

• An orthopaedic emergency: resuscitate as for any major injury.
• Assess for and treat hypovolaemia, anticipate coagulopathy and ensure blood is rapidly available, as a massive transfusion may be required.
• Avoid rolling the patient and instead perform a straight lift with a number of helpers.
• Minimise movement and support an obviously unstable pelvic fracture associated with severe haemorrhage using, for example, medical anti-shock trousers (MAST suit).
