Abstract

Disclosed is an interspinous process spacer to be interposed between the posterior spinous processes of a vertebral body so as to inhibit stenosis among spinous processes. The disclosed interspinous process spacer comprises a main body having a spacing portion to space interspinous processes apart by a predetermined gap, and a blade portion formed at one side of the spacing portion to prevent the separation of the spacing portion, wherein the main body has a predetermined operating space formed at the other side of the spacing portion, and a separation prevention member installed in the operating space such that the separation prevention member is movable between a first location, which is an insertion location, and a second location for preventing the separation of the main body, wherein the separation prevention member prevents the separation of the spacing portion, and is locked at the second location.
