Bone peg with reposition and pressurization functions

The invention provides a bone peg with the reposition and pressurization functions. The bone peg comprises a rod body, a sleeve and a head part. A first male thread and a second male thread are formed at the two opposite ends of the rod body, wherein the first male thread is used for being fixed to a broken bone on a far side. The sleeve is used for being inserted into a broken bone on a close side and provided with a through hole, a female thread meshed with the second male thread of the rod body is arranged on the inner wall of one side of the through hole, the sleeve is made to be annularly connected to the end, provided with the second male thread, of the rod body, and then the broken bone on the close side and the broken bone on the far side are connected. The head part is arranged on the outer wall of the other side, close to the sleeve, of the through hole in an integrally formed mode and used for abutting against one surface of the broken bone on the close side. Consequently, when the head part rotates, relative displacement can be formed between the rod body and the sleeve, and then the two broken bones can oppositely move.
