A comminuted fracture can heal. The treatment options and time to clinical healing vary depending on where the fragmentation fracture occurs. A comminuted fracture is a complete fracture, which means that the bone is broken into three or more pieces and there is usually some misalignment, and treatment requires repositioning, docking of the misaligned bones, and then fixation. Due to its poor stability, it is easy to cause secondary damage and injury to nerves and blood vessels if it is not handled properly or carried properly. In the case of fractures in the joint area, surgical treatment is required for incision and internal fixation. For comminuted fractures of the long bones of the extremities, if there is no obvious displacement or angular deformity, it usually does not affect the function after recovery. Those who are physically unable to tolerate surgery can be treated conservatively with external fixation in a plaster rest. If the physical condition allows, surgical treatment is preferred as much as possible to achieve better and faster recovery of limb function. The healing time of comminuted fracture is usually about 3-4 months, and for comminuted fracture of joint parts, appropriate weight-bearing can be performed after 3 months, and clinical healing of fracture can be achieved in about 6-9 months after clinical follow-up and observation.
