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.
An external bone-anchoring means, comprising two groups of pins, each group being comprised of at least one pin, or the like, for retaining a bone portion, at least one assembly rod for interconnecting the two groups, and at least one arcuate member of polygonal cross-section connected to the assembly rod adjacent one of the groups of pins, the arcuate member having no discontinuities over its length and having a uniform cross-section over its length for enabling the assembly rod to be connected to the arcuate member anywhere along its length.
