Abstract
Abstract An osteosynthetic force transmitting and positioning apparatus has two force transmitting members one of which is slidably telescoped into the other and each of which or at least one of which is connected or is connectable to one or more connecting components for bone screws, bone pins and/or other types of fasteners which secure the connectors to discrete bones, to fragments of bones or to osteosynthetic plates. The connections between the force transmitting members and the connecting components are such that the orientation of the fasteners can be altered in the direction of any one of three axes which are disposed at right angles to each other. Such connections can include fulcra, hinges, pivots, pin-and-hole couplings or others.
