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. |
