A system for spinal fixation with a non-rigid portion at least one of the caudal or cephalad terminus. Various devices and techniques are described for transition from a rigid fixation construct to a less rigid support structure applied to a 'soft zone' that helps share the stress created on the spinal levels caused by the fixed levels below. In some embodiments, the soft zone is provided by terminating the construct with one of a flexible tether or a dampening rod.

Post-operatively adjustable spinal fixation devices

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. More specifically, the application describes instruments and methods for building a posterior fixation construct across one or more segments of the spinal column in a minimally invasive fashion.

Minimally invasive spinal fixation system and related methods

Systems and methods for a guide assembly for introducing a bone anchor to an operative target site. The guide includes an outer sleeve and an inner sleeve. The outer sleeve has a distal anchor engaging end, a proximal end, and a central passage extending from the distal end to the proximal end. The inner sleeve may be situated in the central passage of the outer sleeve. The inner sleeve is movable being between a first position and a second position. The first position permits insertion of the bone anchor in the central passage. The second position releasably fixes the bone anchor to the guide assembly.

Systems and methods for introducing a bone anchor

Disclosed is a surgical alignment and distraction frame and associated methods of use that facilitates correction of a sagittal imbalance. The alignment and distraction frame works in conjunction with pedicle screw installation guide assemblies to impart the desired correction. The alignment frame can be utilized to ensure the pedicle screw housings are aligned (to facilitate rod coupling) in concert with the completion of a correction maneuver.

Spinal alignment frame

A jointed rod assembly for use in a spinal fixation construct involves a caudal rod portion connectable to an adjustment mechanism, and a cranial rod portion connectable to the adjustment mechanism. The adjustment mechanism is configured to rotate the caudal and cranial rod portions relative to one another about a joint axis that is generally perpendicular to the longitudinal axes of the caudal and cranial rod portions. The caudal and cranial rod portions may be dimensioned to be compatible with other pieces of hardware commonly used for spinal fixation, such as bone anchors (e.g., pedicle screws), occipital plates, reducers, and others. The caudal and cranial rod portions are composed of a strong, rigid, non-absorbable, biocompatible material. The jointed rod assembly may be advantageously used in spinal fixation systems and methods of spinal fixation.

Post-operatively adjustable angled rod

A laser or ultrasonic instrument is used to remove tissue during a surgery, such as to form one or more pilot holes in a vertebra or a window in bone. Where a laser is used, interrogative laser pulses can be used to obtain information, such as detecting depth or tissue type.

Robotic surgery

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. Extension guides are provided that attach to bone anchors implanted within the spine. The extension guides have a guide channel that align with a rod channel in the anchor to help direct the rod to the anchor. Instruments are provided to aid in insertion and positioning or the rod.
