摘要:
A spanning connector for connecting an offset bone anchor to a previously inserted spinal fixation element and method of use is provided. The spanning connector includes a first connecting mechanism for connecting the spanning connector to the bone anchor, and a second connecting mechanism for connector the spanning connector to the previously inserted spinal fixation element. The spanning connector also includes a connector body for coupling the first connecting mechanism and the second connecting mechanism. Embodiments of a spanning connector may also reduce a separation distance between the bone anchor and the spinal fixation element. Embodiments of a spanning connector are configured, sized and dimensioned for use in a minimally invasive surgical technique, such as a rod-first spinal surgical technique.
