When a bone is broken, apart from severe pain and swelling there will usually be visible deformity with shortening and angulations of the limb.
Arnica 200 should be given immediately with a dose of two to overcome shock and restrict extravasations of blood and fluids into the surrounding tissues.

Skilled attention and immobilization of the affected part with a plaster cast is inevitable in this case. Moreover,
Arnica 30 twice a day for a few days and, thereafter,
Symphytum 30 twice a day for two weeks helps to establish a firm union of the broken bone-segments. This remedy has also proved of great value in cases of persistent non-union of a fracture.
