How long does it take for a fracture to be cast?

Plaster external fixation after fracture is a commonly used treatment method in clinical practice. The specific fixation time is affected by many factors, such as the location of the fracture, the age of the patient, the severity of the fracture and the healing of the fracture. The shortest time is three weeks, and the longest is 2~3 months. Basically, the younger the patient is, the stronger the healing ability of the fracture, and the shorter the plaster fixation time. Diaphysis is cortical bone, dense and hard, and the time of fixation after fracture is relatively long, because metaphysis is mostly cancellous bone, and the speed of good blood circulation is faster. Fractures of upper limbs are relatively lower limbs fractures, plaster fixation time is shorter, because lower limbs bones are thick, limb weight is large, attached muscle strength is large and also plays a role in supporting weight, so the fixation time is longer, so that the fracture healing is stronger and then the plaster is removed, in case the fracture is broken during the activity. Specific to a certain patient, to the expected time to remove the cast, before removal, but also to carry out x-ray examination and physical examination, to determine whether the fracture healing can be removed cast standards.
