摘要： An adaptable clamping mechanism for coupling an elongate spinal fixation element to a bone anchor is provided. A seat element and a clamp element of the adaptable clamping mechanism adapt to seat and clamp an elongate spinal fixation element whose longitudinal axis is non-perpendicular relative to the as central axis of the bone anchor. One or both of the seat element and the clamp element may adjust to an out-of-plane orientation of the elongate spinal fixation element by pivoting or rotating in one or more directions. One or both of the seat element and the clamp element may have a deformable portion configured to deform to the orientation of a surface of the elongate spinal fixation element. In addition, the seat element may be configured to provide tactile and/or auditory feedback to a surgeon when the seat element and the elongate spinal fixation element are in contact, facilitating proper positioning of the elongate spinal fixation element in the rod seat when using a minimally invasive rod-first surgical technique.

摘要： A rod anchoring system including a bone anchor and a connector is provided. The connector of the rod anchoring system is configured to be inserted in one orientation and then transitioned to a second orientation to connect the rod to the anchor. The bone anchor includes a detachable extension shaft that acts a guide for inserting the connector. In use, once the bone anchor has been implanted at a target site on a vertebra, the connector is placed onto the extension shaft and slid along its length in a first orientation to insert the connector. Once the connector is at the implant site, it is transitioned from the first orientation to the second orientation to connect the rod to the anchor.

摘要： Methods for delivering a spinal fixation element to a surgical site are provided herein. More specifically, the method includes delivering a plurality of percutaneous access devices to a corresponding number of spinal locations, inserting a spinal fixation element through tissue, and manipulating the element through opposed sidewall openings formed in each access device. In an exemplary embodiment, the method can be optimized for position of large-scale fixation elements (e.g., greater than about 95 mm in length). In addition, a manipulation instrument configured to position such spinal fixation elements is also provided herein.
