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.
