After the fracture is fixed in a cast, the time for removal of the cast is usually more than 4-5 weeks, but in some cases it may take longer. Especially for elderly patients and weak patients, their fracture healing time may be extended later, so it is necessary to consider delaying the removal of the cast, because the cast is removed too early after the fracture is fixed, which may lead to non-healing or deformed healing of the fracture, and the postoperative patients may also experience infection of the surgical incision and loosening of the internal fixation, which may also lead to serious internal fixation Because the fracture is not completely healed, it may lead to redisplacement of the fracture site and other complications, so for patients with fracture after cast fixation should be reviewed regularly, you can consider x-ray examination, as well as other relevant examinations, because in addition to observing the fracture, the repair of adjacent soft tissues should be considered. Patients with fractures fixed in a cast should pay attention to the protection of the fixed part of the cast, avoid falls, etc., to avoid re-injury to the fracture site, and also regularly perform imaging examinations of the fracture site to determine when the cast can be removed in conjunction with the imaging results.
