Zusammenfassung:	A height-adjustable vertebral fusion cage, comprising: an inner tube (10), and an outer tube (20) provided as a sleeve on the inner tube (10). The outer tube (20) is connected to the inner tube (10) via a top end. A first notch (210) is provided on the outer tube (20). An outer tube wall between two adjacent first notches (210) forms an expanding portion (220). An end of the first notch (210) is provided with a first position-limiting plate (230) extending along an axial direction of the outer tube (20). A second notch (110) is provided on the inner tube (10). An inner tube wall between two adjacent second notches (110) forms a first supporting portion (120). The position of the first supporting portion (120) corresponds to the position of the first notch (210). In a first compression state, the expanding portion (220) of the outer tube (20) transforms and expands outward and the first position-limiting plates (230) connect to each other. In a second compression state, the first supporting portion (120) of th
