At the accident and emergency department, doctors will assess the injury and determine the extent of the damage—usually with the help of an X-ray. This allows them to estimate how long healing may take and decide on the appropriate treatment. Treatment may involve applying an arm cast with a sling or, in more severe cases, surgery to realign the bones. When a cast is used, the immobilised joints often become stiff, and the muscles weaken. Although strength and range of motion may return with everyday use, recovery is typically slow and may not be complete. This can make simple tasks, like turning a doorknob, challenging.
