    摘要： A spinal stabilization device (700) includes a rod receiving member (701), a collet (200), a plug (300) and a first bone screw (400). The rod receiving member defines a first throughhole (710), a collet recess (720) aligned with the first throughhole, and a rod receiving slot (730) 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. The rod receiving member includes a second bone screw, with the axis of the second hole offset from that of the first hole.

    摘要： A spinal stabilization system (100) includes a shaped spinal rod (10) and a plurality of bone screws (50). The shaped spinal rod includes a body portion (30), a head portion (20) and a neck portion (40) connecting the body portion to the head portion. The shaped spinal rod provides coronal rigidity for a complex deformity construct, and allows for rotation of the shaped spinal rod in a medial and lateral direction to facilitate insertion into the screw head. The bone screws include a housing portion (60) and a screw shaft (52) distally extending from the housing portion. The housing portion includes an inner housing (64) and an outer housing (62) slidably surrounding at least a portion of the inner housing. The inner housing defines a slot (70) configured and dimensioned to releasably secure the body portion of the shaped spinal rod therein. The outer housing is movable relative to the inner housing between an unlock state and a locked state.
