Abstract: Described is a fixateur consisting of a solid rod designed for bridging two portions of a broken long bone, united or ununited, and maintaining the divided portions of the bone in rigid alignment with each other. The solid rod fixateur is designed to be rigidly attached to the damaged long bone by means of a pair of partly tubular plates at either end of the rod. These plates provide the sole means of attachment of the fixateur to the bone i.e there is has no provision for any attachments along, beside or through any portion of the rod that would allow it to be apposed to, or attached to any portion of the bone for which it is providing support for osteosynthesis.
