Follow-Up Study of Modified Luque Instrument (G-Rod) for Spinal Trauma

Luque sublaminar wiring is one of the most rigid spine stabilization techniques, with the advantages of being easy to apply, technically simple, and low in cost [1]. However, its stabilizing capabilities are not perfect, especially against axial loads. The authors have an adaptation of the Luque instrument, called a grooved rod (G-rod), which has a helical groove carved into an original Luque rod (L-rod), with a 2-mm width, an 0.8-mm depth, and a 19-mm pitch. Both rods are shown in Fig. 1.
