Disclosed are devices, systems and surgical methods for treating damaged and / or injured spinal levels involving offset or "slipped" vertebral bodies, such as in the treatment of spondylolisthesis, scoliosis, lateral listhesis and / or retrolisthesis

The present invention provides a single surgical method, procedure and / or system that creates open visual and physical access to an identified spinal treatment site that initially comprises spinal levels to be treated, wherein the spinal levels comprise at least one dorsal root ganglion. A spinal treatment procedure is performed generally in combination with implantation of a neuromodulation system that may comprise placement of electrical lead(s) on the at least one dorsal root ganglion, wherein each lead is in operative connection with a pulse generator that may also be implanted during the surgical method. Electrical stimulation may be generated with the pulse generator through the electrical leads to the at least one dorsal root ganglion during and / or after the closure of the identified spinal treatment site.

Disclosed is a computer-implemented method of registering a digital model of an anatomical body part corresponding to a patient body part. The method encompasses input, to an augmented reality viewing device, of data defining a digital model of an anatomical body part. The model comprises at least one vertex which corresponds to a specific part of the anatomical body part. The specific part is, for example, a landmark easily identifiable for a user, such as a specific vertebra which may be found by palpation. Based on a known orientation of the augmented reality viewing device relative to the anatomical body part, visual information is displayed on a viewing unit of the augmented reality viewing device. The visual information indicates the position of the vertex as an overlay on the position of the specific part of the anatomical body part in the field of view of the augmented reality viewing device.

Various implants and surgical techniques for dynamic spinal tethering systems are discussed. In an example, a spinal tethering system can comprise a flexible elongate spinal tethering cord and a plurality of vertebral implants connecting the cord across at least four spinal levels. In this example, each vertebral implant of the plurality of vertebral implants can include a dynamic head coupling each vertebral implant to the cord. The dynamic head of each vertebral implant can be configured to share cord tension across multiple spinal levels by releasing a first tension generated at a first level between two vertebral implants of the plurality of vertebral implants to generate a second tension across two spinal levels between three vertebral implants of the plurality of vertebral implants, wherein the second tension is lower than the first tension.

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.
