摘要： Disclosed herein is a spinal interbody cage, comprising an upper plate, a lower plate, a screw arbor and two slide blocks. The screw arbor includes a first section with an outer thread and a second section with an outer thread. The outer threads of the first and second sections have opposite directions. The upper plate respectively has a pair of upper plate slanted surfaces proximate to the first and second sections of the screw rod. The lower plate respectively has a pair of lower plate slanted surfaces proximate to the first and second sections. The screw rod is disposed in and cooperates with the inner threads of the slide blocks. The screw rod and slide blocks are arranged between the upper and lower plates. The slide blocks respectively have two slide block slanted surfaces, each abutting and cooperating with one of the upper and lower plate slanted surfaces so as to distance the upper plate from the lower plate when the slide blocks are distanced from each other by rotating the screw rod in one direction.
