The vast majority of elbow bone crushing is not fully recoverable, and in severe cases, good repositioning is often not possible, which may lead to joint dysfunction. Due to the crushing of the joint bone, some patients may suffer from joint displacement, joint stiffness and inversion deformity after surgical fixation, resulting in significant limitation of elbow joint movement, reduction of joint mobility of neighboring joints, muscle atrophy and other functional disorders. Surgical treatment is needed if the elbow joint is fractured, with internal fixation with plate screws or Kirschner’s pins, and external fixation with plaster cast after surgery. If the fracture is severe, joint replacement should be considered. Later, radiographs should be taken to determine the recovery of the fracture, and when it is relatively stable, functional exercises can be carried out to restore normal flexion and extension of the elbow joint and stress activities. When the elbow joint bone broken, need to go to the hospital in time, follow the doctor’s instructions for treatment.
