With the rapid development of medical technology, many orthopedic diseases such as osteoarthritis, joint injuries, cervical spondylosis and lumbar disc herniation have been treated with good results through surgery, which can significantly relieve patients’ pain. Generally, patients have been walking on the ground within one week after surgery and can complete basic daily life by the time they are discharged from the hospital. Therefore, many patients think that surgery is the most important part of the treatment, and a good postoperative effect means that everything is fine and done once and for all; if there is no recurrence or aggravation of symptoms, they do not need to review again; in addition, they are busy at work, and the procedure of follow-up at the hospital is tedious and the waiting time is long, so they are more reluctant to come back for a review. In fact, as the ancient saying goes, “Half a hundred miles is half a hundred miles”, the completion of surgery is only a stage in the treatment of disease, and regular follow-up and rehabilitation guidance after surgery is a very important part of the disease treatment process, which is important for restoring limb function, consolidating the effect of surgery, reducing the recurrence rate after surgery and preventing accidents. Generally speaking, postoperative review can be divided into three stages, namely early, middle and long term. So, what are the contents of the postoperative review, what time is needed to review and how to review the most convenient? Early postoperative period generally refers to six months after surgery, the main task of this stage is to guide patients from the previous pain and surgical trauma how to scientifically and quickly restore the function and daily life and work. Some patients are bold, have good physical quality and fast functional recovery, so they carry out postoperative functional exercise prematurely and excessively; some patients are cautious and have average physical condition, so they are overly worried about postoperative complications, which leads to a big discount of functional exercise and cannot resume normal life for a long time, these biased understanding of surgery and wrong rehabilitation methods will affect the treatment effect; in addition, this stage also needs to observe and prevent Post-operative infection, changes in the position of the internal fixation, changes in the body’s internal environment, etc., should be observed and prevented during this stage, and X-rays and blood tests should be performed according to the different diseases during the follow-up. Therefore, regular communication with the doctor and receiving guidance are needed, and the time interval of this stage of review is also intensive, usually for 6 weeks, 3 months and 6 months after surgery. The mid-term postoperative period generally refers to six months to two to three years after surgery, during which time the patient’s physical condition has become more stable and some patients return to sports or to their busy work and life. The main purpose of the review is to regularly observe whether there is any change in the position of the internal fixation (whether it needs to be taken out or adjusted), whether there is any disease in the relevant parts and to guide the patient in functional exercise, so the time interval is gradually extended, usually 1, 2 or 3 years after surgery. Some diseases, such as most fractures, heal within this period and can be reoperated to remove the internal fixation. The long-term postoperative review is mainly for the observation and disposition of the patient’s long-term outcome, let’s take two examples to illustrate. For example, for patients who have had artificial joint replacement, with the extension of time, the material of artificial joint will gradually wear out, the firmness of prosthesis fixation may gradually decrease, and there is a possibility of late infection and other complications, so it is necessary to regularly observe the patient’s imaging and limb function, changes in adverse symptoms, and take corresponding disposal measures if necessary; for patients who have had spinal surgery, especially for patients who have internal fixation material placed in the body, with the extension of time, it is necessary to take corresponding disposal measures. For patients who have undergone spinal surgery, especially for patients with internal fixation materials, lesions of the spinal structures adjacent to the surgery may occur over time, as well as loosening of the internal fixation materials and delayed infection; according to the characteristics of this stage, the review can be conducted every two years, and if more than 10 years after surgery or if there are signs of the above-mentioned complications, the review interval can be shortened according to the situation, and if necessary, the doctor will handle the situation accordingly. So how can the review be done conveniently? First of all, you should choose the right doctor. Generally speaking, the doctor in charge and the doctor in charge during the hospitalization period know the patient’s condition best, therefore, you should ask them in detail about their clinic hours when you are discharged from the hospital, and it is better to visit their clinic; before the review, it is better to make an appointment with the doctor by internet or telephone if possible, so that your treatment will not be affected due to the adjustment of clinic hours or other reasons. It is best to bring your medical records, imaging films and previous follow-ups during your stay in the hospital, so that your doctor can systematically analyze and compare the changes in your condition and give you accurate advice and guidance; finally, please always use the same consultation code when you visit the same hospital, which is called “ID number” in most hospitals. This is the unique identification of each patient in the hospital. Through the “ID number”, the doctor can easily retrieve your past medical records in the hospital information system, which also facilitates the doctor to accurately and reasonably analyze each patient’s condition.
