Spinal tethering devices, systems, and methods

A spinal tethering system comprising:

• a flexible elongate cord;
• and
• a first vertebral implant, a second vertebral implant, and a third vertebral implant, each of the first vertebral implant, the second vertebral implant, and the third vertebral implant comprising:
• an anchor insertable within a respective vertebral body;
• a fastener including a shank at a distal end that is insertable into the respective vertebral body through a central passage within the anchor, the fastener including a saddle at a proximal end;
• and
• an assembly comprising a cord clamp and a set screw, the cord clamp comprising a clamp extension extending beyond the saddle when the cord clamp is secured within a cord recess;
• wherein the cord clamp is insertable into a proximal end of the saddle;
• wherein the cord clamp and the saddle define the cord recess for the flexible elongate cord;
• and
• wherein the set screw is operable to secure the flexible elongate cord within the cord recess.

A spinal tethering system comprising:

• a plurality of vertebral implants, each vertebral implant of the plurality of vertebral implants implantable into a lateral portion of a respective vertebral body, each vertebral implant of the plurality of vertebral implants comprising:
• a fastener including a shank at a distal end and a saddle at a proximal end, the shank operable to be inserted into a respective vertebral body, the saddle including a first saddle arm and a second opposing saddle arm;
• a cord clamp insertable into a proximal end of the saddle, wherein the cord clamp, the first saddle arm, and the second opposing saddle arm define a cord recess operable to receive a flexible elongate cord;
• and
• a set screw operable to secure the flexible elongate cord, once received, within the cord recess;
• wherein the cord clamp is engaged with at least one surface of the first saddle arm and the second opposing saddle arm when the flexible elongate cord is secured within the cord recess;
• wherein a bore of the cord clamp extends between a first surface of the cord clamp and a second surface of the cord clamp, the bore is dimensioned to receive an extension of the set screw when the flexible elongate cord is secured within the cord recess;
• and
• wherein the extension extends through the bore and beyond the second surface when the flexible elongate cord is secured within the cord recess.
