The distraction system for long bones includes a guide socket (42) and an intramedullary pin (10). It will make possible, in addition to elongation, also a segmental dislocation, as well as a segmental dislocation in combination with an elongation without repeated surgical intervention, while assuring a sufficient pressure on the bone contact surfaces of the docking site. Intramedullary pin (10) is thus provided on its outside wall with a projection (41) which engages in a longitudinal hole (43) in guide socket (42), whereby intramedullary pin (10) is secured against rotation by means of guide socket (42) attached in the long bone, but can be displaced axially.
