摘要:
A method of treating a spinal column shape deformation includes fixing at least two fixation screw assemblies to respective vertebrae, sliding a rod between the arm extensions on each of the fixation screw assemblies, swinging the channels of the screw assemblies relative to the fixation screws so that the channels become less inclined to the axes of the fixation screws, and so that the rod is located generally posteriorly of the spinal column, locking the channel against swinging relative to the screw, rotating the rod about its axis relative to at least one of the channels, and locking the rod against movement relative to the channel.
