How would i know if my fracture radius and ulna are healing?

Pain and x-rays: The 2 primary indicators of fracture healing are resolution of pain and x-rays. If your pain is improving or gone then that's usually an excellent indication that the fracture is healing or healed. X-rays are used to confirm fracture healing as well.

Splint or castn is often used until soft tissue swelling reduces EARLY motion MAY be offered but each injury different
