I've found interesting post "The difference between Smith's Fracture and Co…" using MEDizzy app. Click the link to view it ;-) https://s4pqd.app.goo.gl/foyggz2KmApa4KhW9
Both are exactly opposite of each other...smiths fracture happens due to fall on dorsal forearm or flexed wrist... Where as colle fracture occurs due to falling on extended wrist
Distal fracture fragment is displaced ventrally in smith fracture..
A Smith's fracture, also sometimes known as a reverse Colles' fracture or Goyrand-Smith's, is a fracture of the distal radius. It is caused by a direct blow to the dorsal forearm or falling onto flexed wrists, as opposed to a Colles' fracture which occurs as a result of falling onto wrists in extension.
If the fracture occurs outside it is colles # and if it occurs inside it is called smiths #
