More than two months after a pelvic fracture, it may be normal to sit up and still have pain in the hip. However, it is not normal if it is due to sequelae such as osteomyelitis and chronic pain. Pelvic fractures are often caused by high-energy violence. Determining whether it is normal to sit up and still have pain in the hip more than two months after a pelvic fracture is case-by-case and cannot be generalized. If the pain is due to the presence of a hematoma or scab formation, combined with the patient’s inappropriate movement while sitting up, it is generally considered normal and indicates that full recovery has not yet occurred. However, if it has been more than two months since the pelvic fracture and there is still pain in the buttocks when sitting up because of sequelae such as osteomyelitis and chronic pain, this is not normal. Usually, patients with pelvic fracture need to immobilize their pelvis, have balanced nutrition, and keep their wounds clean and dry during recovery. To summarize, it is recommended that patients who have pelvic fracture for more than two months and still have pain in the buttocks when sitting up should go to the hospital in time to clarify the specific cause and cooperate with the doctor for active treatment if necessary.
