External bracing for open tibiofibular fractures is usually removed in normal adults in about 2 to 3 months, depending on the individual. External brace fixation is a method of fixing the fracture end after reduction directly outside the body. It is mainly for open fractures or postoperative osteomyelitis. Generally, the external fixator can be removed when the X-ray examination shows the fracture is healed in 2~3 months after the operation, but the time of removal may be prolonged when some patients are old or there are other factors affecting the healing of the fracture. If the fixation pinhole is large, it is recommended to take a rest for 3~4 weeks to avoid pinhole fracture; if the pinhole is small, walking exercise can be carried out gradually after removal. It is recommended to consult the relevant doctor for the exact time of removal.
