Pelvic fracture

Fracture of ilium
Hip fractures

A pelvic fracture is a break of the bony structure of the pelvis. This includes any break of the sacrum, hip bones (ischium, pubis, ilium), or tailbone. Symptoms include pain, particularly with movement. Complications may include internal bleeding, injury to the bladder, or vaginal trauma.

Common causes include falls, motor vehicle collisions, a vehicle hitting a pedestrian, or a direct crush injury. In younger people significant trauma is typically required while in older people less significant trauma can result in a fracture. They are divided into two types: stable and unstable. Unstable fractures are further divided into anterior posterior compression, lateral compression, vertical shear, and combined mechanism fractures. Diagnosis is suspected based on symptoms and examination with confirmation by X-rays or CT scan. If a person is fully awake and has no pain of the pelvis medical imaging is not needed.

Emergency treatment generally follows advanced trauma life support. This begins with efforts to stop bleeding and replace fluids. Bleeding control may be achieved by using a pelvic binder or bed-sheet to support the pelvis. Other efforts may include angiographic embolization or preperitoneal packing. After stabilization, the pelvis may require surgical reconstruction.

Pelvic fractures make up around 3% of adult fractures. Stable fractures generally have a good outcome. The risk of death with an unstable fracture is about 15%, while those who also have low blood pressure have a risk of death approaching 50%. Unstable fractures are often associated with injuries to other parts of the body.

Hip fractures are increasing in frequency in the UK and are expected to at least double by the end of the century. This is partly attributed to the aging population, and partly to inadequate diet. Women are ten times more liable to have hip fractures than men, and loss of density of bones (osteoporosis) accelerates after menopause.
