Abstract
Two spacer components and a retaining ring are part of an orthopaedic system. The system may also include trial or implant stem components that are inserted or implanted in the proximal and distal ends of the long bone. One spacer segment has a male portion and the other spacer segment has a transverse female slot. The male portion and female slot are positioned to allow the male portion to be moved into and out of the female slot in a direction other than the proximal-distal direction. The retaining ring is then threaded into a locked position to limit relative movement between the male portion and female slot. The spacer segments can thus be connected after the segments have been connected to the native bone without damaging the soft tissue at the native bone through distraction.
