How long can the cast be removed for all limb fractures depends on the patient’s fracture healing condition, generally speaking, the upper limb fracture can be removed after 4~6 weeks, and the lower limb fracture can be removed after 6~8 weeks.
Patients with fractures of all four limbs need to stay in bed for a long time, and the healing time is relatively long. Generally speaking, the upper limb fractures can be removed from the cast after 4~6 weeks of treatment and review x-ray suggesting that the fracture end bone scabs are formed, and the upper limb joints can be flexed, extended and rotated for functional exercises gradually. The fracture of the lower limb should be reviewed after 6~8 weeks and the X-ray will show the formation of bone crust at the fracture end, and the cast can be removed.
The duration of cast immobilization should not be too short to avoid causing instability of the fracture, but also should not be too long to avoid causing stiffness of the hand joints and thus affecting the hand function. Therefore, it is recommended that the patient go to the hospital regularly to review the X-ray of the fracture site, and according to the specific healing situation, the doctor will decide the specific time to remove the cast.
