The device comprises common sized superior and inferior elements, that articulate with a variable sized central spacer. The central spacer is available in 12mm to 16mm with 2mm increments to accommodate different anatomies. The superior and inferior elements have toothed edges to assist fixation to the bone.
S1 HOOK IMPLANT
A lot of interspinous implants cannot be implanted at the L5/S1 level because of the lack of a spinal process on the sacral prominence. Accordingly, hpi’s innovative solution is the design of an S1 hook implant, allowing the surgeon to create an artificial S1 spinous process that the Flexis can be placed onto.
