Patient: Hello doctor! I fell down the stairs on July 7, 2007, and my foot was red and swollen with pain, and I took a shower for more than an hour that day. The swelling disappeared but the pain still existed, and I also had my foot massaged by a “native doctor”, which made me feel much better at that time. I think if I take it out, it is better to find a general surgeon to take it out with ordinary instruments, doctor! What is the success rate of removing this small piece of bone? How long does it take to walk and what do I need to eat? Do I need anesthesia before removal? Do I need to clean the wound and take anti-inflammatory medication after removal? I hope the doctor can advise me whether arthroscopy or general surgery is better or whether there is other better treatment and how much it usually costs? I want to have this surgery in a general hospital, is it possible? I went to the hospital in the middle of this year to have my blood tested and my hyperthyroidism checked, both of which were fine. The orthopedic department of the PLA 304 Hospital, Zhang Yadong: Your injury at the time actually led to an “ankle avulsion fracture”, which is a very common (especially on the outside) and easily misdiagnosed and mistreated fracture. As a result, the ankle ligaments may become dysfunctional, leaving behind some symptoms that are difficult to relieve. The first thing you need to do is to determine the size of the avulsed bone (which is not “free” but attached to the ligament and is completely different from the free body of the joint) and especially the stability of the ankle. The size of the avulsed bone (in fact, it is not “free”, it is attached to the ligament and is completely different from the free body of the joint. If the avulsion is small and the ankle is stable (which is not often the case!) If the avulsion is small and the ankle is stable (which is not often!), the avulsion can be simply removed (not “taken out”) by arthroscopic means, but currently most of the surgical methods are still incisional. The success rate is almost 100%, generally 3 weeks can be normal walking, diet does not need special attention, surgery requires anesthesia, generally need 3 days of post-operative infusion treatment. The cost is about 5000 to 7000 RMB. However, in fact, more patients’ ankle joint stability has been destroyed, which is why they have many symptoms. If this is the case, the torn bone block cannot be simply removed, but the ankle ligaments need to be repaired or reconstructed. This is a more delicate surgery and should be treated in a large hospital with a slightly longer recovery time.
