1. A device comprising: a. an internal fixator for spanning a fracture, the internal fixator having a plurality of layers, each layer of the plurality of layers including a thermoplastic component and a fiber component and each layer of the plurality of layers having a selected fiber angle pattern, wherein the internal fixator defines a first aperture transverse to a longitudinal axis of the internal fixator, the first aperture having a central axis, and wherein the internal fixator includes one or more radio-opaque markers that extend substantially parallel to the central axis of the first aperture, b. the selected fiber angle patterns being arranged symmetrically from a first layer to a last layer, and c. the symmetrical arrangement of fiber angle patterns including at least two layers having generally opposing fiber angle patterns.
