Complications
Complications are likely to result in cases of excess blood loss or puncture to certain organs, possibly leading to shock. Swelling and bruising may result, more so in high-impact injuries. Pain in the affected areas may differ where severity of impact increases its likelihood and may radiate if symptoms are aggravated when one moves around. Causes
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. Pathophysiology
The bony pelvis consists of the ilium (i.e., iliac wings), ischium, and pubis, which form an anatomic ring with the sacrum. Disruption of this ring requires significant energy. When it comes to the stability and the structure of the pelvis, or pelvic girdle, understanding its function as support for the trunk and legs helps to recognize the effect a pelvic fracture has on someone. The pubic bone, the ischium and the ilium make up the pelvic girdle, fused together as one unit. They attach to both sides of the spine and circle around to create a ring and sockets to place hip joints. Attachment to the spine is important to direct force into the trunk from the legs as movement occurs, extending to ones back. This requires the pelvis to be strong enough to withstand pressure and energy. Various muscles play important roles in pelvic stability. Because of the forces involved, pelvic fractures frequently involve injury to organs contained within the bony pelvis.
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. Signs and symptoms
