An expandable spinal implant includes a flexible body, an expander component, a fastener and an anti-reverse mechanism. The flexible body includes a base portion and flexible arms each having a free end and a fixed end connecting the base portion. The flexible arms surround an installation space. The expander component is partially in the installation space and exerts pressure on the free ends to move the free ends away from one another. The fastener includes a head portion and a screw portion. The head portion and the expander component are at opposite sides of the base portion. The screw portion passes through the base portion and screwed into the expander component. The anti-reverse mechanism is fixed to the base portion and blocks one side of the head portion located away from the expander component. The anti-reverse mechanism and the expander component are at opposite sides of the base portion.
