Abstract
Apparatus for the external setting or securing of the parts of a fractured bone, comprising an elongate central body member comprised of two parts mutually displaceable parallel to the longitudinal axis of said member, whereby each part of the central body member supports a clamping device for the pins to be inserted into a part of the bone. The two mutually displaceable parts are engaged by a pressing and tensioning device causing the mutual longitudinal displacement of the part. When the pins are inserted in the bone parts to be pressed together, the pressing and tensioning device is actuated until the two bone sections abut against each other at the required pressure. Then the securing devices fix the two parts of the central body member into their position. Subsequently, the pressing and tensioning device is removed from the central body member since it is no longer required. For reliable guidance the two parts of the central body member are telescopically inserted one within the other and universal joints are provided between the central body member and the clamping devices for compensation. These universal joints after being mounted on the bone to be put in splints are adapted to be fixed by fixing devices, so that a completely stable position of the whole apparatus is provided. The pins to be inserted into the bone parts for reliable anchorage, in view of the tractive forces occurring at least in the section of the pin insertable in the bone, are provided with an external thread.
