Abstract: Methods and devices are disclosed herein that generally involve applying thermal therapy to tissue (e.g., localized cooling or heating of tissue), and in particular applying thermal therapy to the spinal canal, tissue disposed within the spinal canal, and/or nerve roots extending from the spinal canal. In some embodiments, tissue can be cooled or heated by implanting a malleable or deformable thermal device in proximity to the targeted tissue. The thermal device can be left in place following surgery to facilitate application of post-surgical thermal therapy. In some embodiments, the thermal device can be removed post-surgery in a minimally- or non-invasive manner. The thermal device can be connectionless or can include penetrable regions, pre-attached tubing, or detachable connectors to facilitate application of cooling or heating means to the device. Methods are disclosed for utilizing thermal devices and for carrying out various treatment regimens that involve cooling or heating tissue using such devices.

Abstract: Compression-distraction spinal fixation systems, and methods of performing compression-distraction spinal fixation, are provided that include screw-rod constructs having a ratcheting mechanism. Bone screws of the screw-rod constructs can have a pawl that engages ratchet teeth on the rod of the screw-rod construct. The bone screw can be ratcheted along the length of the rod to apply distractive or compressive forces.
