The bone is usually crooked because of the previous history of fracture, after the bone is crooked, we should take a film to see the X-ray film to show the specific degree of deformity of the bone, how the alignment of the bone is in the end, and whether there is any impact on the future in this state, and to judge these conditions. If there is no special impact on the later recovery, it can be corrected by itself and the current position can be maintained. On the other hand, if it affects the joint activities and cannot meet the normal daily life, we should consider surgery to correct the deformity through internal fixation of the osteotomy, and slowly heal in the corrected position to minimize the impact of the deformity healing, and then regularly review the healing of the fracture by taking pictures and carry out appropriate functional rehabilitation exercises.
