An ulnar radius fracture can be removed from the sling after about 30 to 50 days after surgery. When an ulnar radius fracture is internally fixed after surgery, the sling can usually be removed about 30 to 50 days after surgery. However, it also depends on the patient’s specific recovery. For more serious ulnar radius fracture patients such as comminuted fracture, it is recommended that the braking time can be appropriately extended, and the time of wearing a sling can be extended to about 60 days. This is because the sling not only helps the formation of bone scab, but also promotes venous return, thus helping the symptoms of upper limb swelling disappear. The above situation should be reviewed regularly and the sling should be removed under the doctor’s instruction so as not to affect the normal recovery after surgery.
