Two broken ribs generally take about 3 months to reach clinical healing standards after regular conservative treatment, and the specific healing process is divided into 3 stages. The first stage, 2-4 weeks after the injury, is the local hematoma inflammation mechanization machine, this period is mainly through the absorption of local hematoma to complete the fibrosis. The second stage, 4-8 weeks post-injury, is the primary bone scab formation period, during which the primary bone scab is formed through both intra-membranous and endochondral osteogenesis, thus completing the initial joining of the two fractured ends. The third phase, 8-12 weeks after injury, is the scab shaping phase, which restores the bone to its original strength and firmness at the rib fracture site through shaping. Therefore, it takes 3 months after the injury to reach the standard of clinical healing.
