Abstract
A method and apparatus for the fixation of bone fractures, limb lengthening, and the correction of deformities uses an improved composite plastic carbon fiber ring that is formed in a mold, or machined with a stepped end portion that allows half rings to be assembled in a common plane. The method can use a mold wherein multiple rings can be formed by stacking the rings with a Teflon layer therebetween and wherein circumferential braid reinforcement of carbon fiber adds strength at the circumferential inner and outer curved surfaces of the rings and half rings.
