The criteria for healing of a femoral stem fracture are the absence of pain on localized pressure, the absence of pain on longitudinal percussion, the absence of any abnormal sound or activity at the fracture site and the presence of faint shadows in the fracture line on radiographs, and the presence of a continuity of bone crust through the fracture line. Fracture is the destruction of the continuity and integrity of the bone due to external forces and other factors. Clinical manifestations after fracture are mainly pain, swelling, limitation of activity and dysfunction at the fracture site. The criterion for fracture healing is the disappearance of the clinical manifestations of the fracture. The main healing criteria are: 1. No localized pain in the fracture, no longitudinal percussion pain. 2. No abnormal activity at the fracture site. 3. Imaging examination: X-ray examination suggests that the fracture line is blurred and there is continuity of bone crust passing through the fracture site. It is recommended to go to the hospital for examination and then have the doctor to synthesize the specific situation to determine whether the healing.
