Why does distal radius fracture cause visible deformity after injury?

The distal radius forms the wrist end of one of the forearm bones. When it breaks, the bone fragments can shift or tilt, especially during the force of a fall onto the hand. That change in alignment can create a bend, step, or altered profile at the wrist. Swelling and bruising can make the outline look more pronounced.

The appearance gives a clinician a reason to assess the wrist, but it does not show the exact fracture pattern or alignment. X-rays and an examination help determine the position of the bone and check the skin, circulation, nerves, and finger movement.

Support the arm in the position found and avoid trying to straighten the wrist. Remove rings before swelling develops, keep the hand elevated if comfortable, and protect the area from further impact. A temporary support can reduce movement while you arrange medical care, but it should not be tight. Follow professional instructions about food, drink, and pain relief if a procedure may be needed.

Arrange urgent medical assessment for a wrist that looks bent after an injury, particularly when pain, swelling, or loss of movement is present. Seek emergency help if the fingers are numb, cold, pale, blue, or difficult to move, or if bone has broken through the skin. Do not wait for the appearance to improve on its own.

What does the imaging show about alignment and the joint surface? Will the wrist need a cast, reduction, or another treatment? How should I protect the hand, and when will movement therapy start?
