A broken pelvis is clinically diagnosed as a pelvic fracture. How long it takes for a pelvic fracture to heal depends on the patient’s age and the extent of the fracture, as well as the type of treatment used. If a pelvic fracture occurs in a child and there is no major displacement of the fracture, it can be treated conservatively. Clinical healing can be achieved in about 4-5 weeks after proper treatment. If the pelvic fracture occurs in an adult and the displacement is large and there is displacement of the sacroiliac joint. In this case, surgical treatment is required and clinical healing of the fracture can be achieved in about 7-8 weeks after surgery. In addition, if the pelvic fracture is combined with a bladder or urethra injury, the healing time will be a little longer. If a pelvic fracture occurs in an elderly person, the fracture heals more slowly due to osteoporosis, and the healing time is about 8-10 weeks before clinical healing is achieved.
