Pelvic fractures that are displaced fractures or that cause the pelvic ring to become dislocated may be stabilized through external fixation or internal fixation surgery, according to UW Medicine Orthopaedics and Sports Medicine. Both types of fixation surgeries can stabilize any pelvic ring fractures.
Pelvic external fixation surgery typically consists of an orthopedic surgeon placing pins into the iliac bones and connecting the bones through clamps and bars, according to UW Medicine Orthopaedics and Sports Medicine. Internal fixation surgery involves application of plates and screws to the fracture site after the pelvic ring has been realigned properly. Certain pelvic fractures may also require surgical intervention that is a combination of external and internal fixation.
