Fracture healing is a chronic process, which needs to go through the period of hematoma radicalization, bone scab formation and bone scab shaping. The healing time of comminuted fracture is usually about 3-4 months, and some patients may have non-healing or delayed healing due to heavy injury and local soft tissue, muscle and periosteal damage. A comminuted fracture is a complete fracture in which the bone is broken into 3 or more pieces, usually caused by direct violence, and is accompanied by local muscle, blood vessel, nerve damage, or even joint damage. The healing time of a comminuted fracture is affected by many factors, including the location of the fracture, the fracture pattern, the cause of the injury, the infection of the fracture end, the treatment method and the treatment technique, etc. Most patients can achieve healing in about 3-4 months. Patients with comminuted fractures usually require braking and are often constipated, so it is recommended to consume more fibrous foods to keep the bowels open.
