Depending the part
Depends on which bone and type of fracture
Humerus and communited fracture-no. The movement of upper arm depends on shoulder& humerus muscles, nerves, tendons & ligaments. Any serious injury to these parts decreases the movement. Radius, ulna, carpals and metacarpals, you can have injury, but still would be able to move. Your orthopedist can guide you about movement. Thanks.
