Pelvic fracture is a stable fracture if it doesn't involve the structural damage of pelvic ring (you need to specify where the fracture is so that I can judge whether it is a stable fracture), and unstable fracture is generally multiple fractures. Stable fractures are generally treated by bed fixation combined with medication, while unstable fractures need traction external fixation or surgical internal fixation combined with medication. The parts of pelvic fracture include: upper and lower branches of pubic bone fracture, upper and lower branches of ischium fracture, pubic symphysis separation, iliac wing fracture, bilateral iliac basal joint separation fracture, acetabular fracture, pubic comb fracture, etc.
So, you can talk about the fracture site first, or ask a doctor for a diagnosis. Let me have a look and help you analyze it, which can help you decide the specific treatment plan! I hope it helps you!
