Hey, she has a fracture of the one of the bones of the wrist. She needs to be given a splintage for support. You can roll a newspaper to form a splint n tie it loosely with a cloth piece, from hand till elbow. Give her some analgesics for pain relief n elevate the wrist by keeping it on 2 pillows besides her. In the morning take her to an orthopaedic surgeon.

There's a fracture at the wrist joint. For temporary pain relief give some pain killer and consult near by orthopaedic surgeon for further management.
