摘要

The anterior vertebral clamp comprises two parallel bars (3) which fit into bores in connector plates (2) at either end. The bars are locked in place by bolts (10) which fit into vertical bores (9) at their ends. The clamp is anchored to the vertebrae by two bolts (4) which are on opposite sides of each plate and offset with respect to its transverse axis (XX').
