How long it takes to be discharged from the hospital with a fracture of seven ribs depends on the specifics of the fracture and whether there are any combined injuries. A simple rib fracture fixed with a chest strap, no damage to the lung, no accumulation of blood or fluid, and no pain after fixation can be discharged, after about 10 days of swelling and pain relief. If there is a skin laceration or other injury that requires sutures, you can be discharged after 10-15 days of stitch removal and observation without infection. If there is a rib fracture with a shackled chest, seven rib fractures that severely damage the lungs and cause blood and fluid accumulation, and also if the rib fracture has a crushed displacement or the damaged muscle is more serious, it is not possible to discharge very early. Pleural effusion requires tube placement and fluid extraction, and also requires regular examination of the lungs, which needs to be judged according to the specific recovery situation, and takes 1-1.5 months, which is only a general estimate, and requires examination by the attending physician to see the time of hospitalization according to the recovery situation.
