摘要：
A spinal stabilization device includes a rod receiving member, a collet, a plug, and a first bone screw. The rod receiving member defines a first throughhole, a collet recess aligned with the first throughhole, and a rod receiving slot offset from the first throughhole. The collet is insertable into the collet recess and defines an aperture, a plug recess aligned with the aperture, and a wall portion defining a rod securing slot configured to fix the spinal rod therein. The collet is transitionable between a first diameter, where the rod securement region defines a first diameter, and a second diameter, where the rod securement region defines a second diameter. The plug is insertable within the plug recess, and transitions the collet between the first and second diameters. The first bone screw includes a head portion and a threaded portion, and is insertable through the rod receiving member and the collet.
