Elbow fractures generally recover better because most of the bone around the elbow joint belongs to the category of cancellous bone, which has relatively good blood circulation and the fracture heals relatively well. Whether treated conservatively or surgically, the fracture will heal well in about three months, or within six months if the time is extended slightly. However, although the elbow fracture is better to recover, the function of the elbow joint is not easy to recover. If the elbow joint is not properly exercised after the fracture, it will easily lead to joint stiffness. Therefore, it is important to strengthen the functional exercise of the joint while treating the elbow fracture, so as to restore the function of the elbow joint as much as possible and avoid the stiffness of the joint.
