Method and apparatus for the fixation of bone fractures, limb lengthening and the correction of deformities

摘要

Apparatus for the fixation of bone fractures, limb lengthening, and the correction of deformities comprises an improved composite plastic carbon fibre ring that is formed in a mould, or machined with a stepped end portion that allows half rings to be assembled in a common plane. In the manufacture of the apparatus a mould may be used wherein multiple rings can be formed by stacking the rings with, eg. a polytetrafluoroethylene layer therebetween and wherein circumferential braid reinforcement of carbon fibre adds strength at the circumferential inner and outer curved surfaces of the rings and half rings.
