Abstract
Tether clamping assemblies, such as clamping assemblies used to clamp a tether about a spinal feature to assist in spinal fixation, and related methods and systems. In some embodiments, the assembly may comprise a tether configured to engage a bone or other anatomical feature, an inner coupling piece, and an outer coupling piece. A first passage may be at least partially defined by an inner surface of the outer coupling piece and an outer surface of the inner coupling piece. The first passage may be configured such that the tether can be clamped in between the inner surface and the outer surface to allow the tether to move through the first passage in a first direction and apply a force differential such that movement of the tether in a second direction opposite the first direction is made more difficult.
