Fixation can be divided into two types: external fixation and internal fixation. External fixation refers to the use of casts, splint supports, etc. to achieve fixation outside the body. Internal fixation refers to the technique of using metal or biomaterials to maintain alignment and stability of the fracture after it has been repositioned through orthopedic surgery. If you implement internal fixation treatment, it is not necessary to remove the internal fixation because with the progress of technology, the metals used to manufacture the internal fixation devices are chosen after repeated tests, they are safe and non-toxic to human body, they are well compatible, it is difficult for patients to feel their presence, they neither cause pain nor special discomfort, and some people can carry them for life. However, they are after all fundamentally different from the living tissues of the organism and are ultimately a foreign body, which may cause adverse reactions when left in the body for a long time. Most patients, especially young patients, still need to remove the internal fixation, which means that after a period of recovery after you are discharged from the hospital. This means that you will need to return to the hospital after a period of recovery, so you must be concerned about when the fixation will be removed. If the fracture is completely healed and the support of the internal fixation is no longer needed, and the movement of the joint adjacent to the fracture has been restored to the maximum extent possible, the functional exercise will not be affected by the surgery to remove the internal fixation. The internal fixation can be removed at this time. The exact timing should be determined by the surgeon. In principle, it is better to postpone it rather than to advance it, except for those who cause complications. The compression plate is very strong. After fixation, it bears most of the stress on the bone, and the plastic period after fracture healing is often long, so early removal of the plate is prone to re-fracture. Therefore, the removal time should be delayed later than the general steel plate. Foreign experts recommend that the time to remove the internal fixation device is 1 year for tibia, 2 years for femur, and 1.5-2 years for forearm bone and humerus. Individual patients with high surgical risk or advanced age can also be suspended and observed for a long time. However, this is not absolute, in children’s fractures such as supracondylar humerus fracture, the healing is faster and the internal fixation can be removed usually 4-5 months after surgery. In some special cases, such as infection at the fracture site, the internal fixation needs to be removed even if the fracture site is not healed, because once the wound is infected, the internal fixation becomes a foreign body and can lead to non-healing of the wound. In a few cases, the location of the internal fixation device happens to be close to the nerves and blood vessels, and the anatomical level of the secondary surgery is not clear, which increases the chance of injury. In addition, there is also due to the bone growth is too firm, the internal fixation equipment buried in it, it is difficult to find, or screw tail groove injury shallow, or nail, pin, wire broken, removal of the trouble, or even can not be removed. Experienced orthopedic surgeons will deal with the patient appropriately according to the specific situation.
