Abstract: Broken bones are externally anchored by various embodiments of the disclosed invention. In each of the embodiments one or more arcuate members pass around the bone to be anchored. Pins extend from the arcuate members to and may also transfix the bone to be anchored. In some embodiments, there are a plurality of arcuate members. In some of the embodiments, the arcuate members encircle the bone. Various auxiliary support pieces are attached on the arcuate members. Some of these auxiliary support pieces help anchor the arcuate members. Other of these auxiliary pieces provide additional supports for additional bone supporting pins. The pins may be held on swivel joints so that the pins may be swiveled for properly engaging a bone. The arcuate members are attached to support supports which enable the anchoring arcuate members to extend to other supporting elements.

Abstract: Apparatus for orienting and securing a rod in a spatially adjusted position comprising a U-shaped element having opposed parallel branches and a bottom portion connecting the branches. At least two superposed plates are disposed between the branches and the plates have mating faces with grooves therein cooperatively defining a hole receiving a rod. A flange is detachably secured to the branches of the U-shaped element to hold the plates and rod between the branches. The top plate is connected to the flange for rotation about an axis parallel to the branches and the bottom plate is rotatable with respect to the U-shaped element about the same axis. As a consequence, the rod can be angularly rotated with the plates in a plane perpendicular to the branches.
