Abstract
The disclosed embodiments provide a system including an implant assembly and an instrument configured to work in conjunction to manipulate vertebral bodies to affect derotation. The implant assemblies include a removable attachment element that allows for the attachment of the instrument. The instrument is configured to attach to two implant assemblies that have been inserted bilaterally into a vertebral body. When the instrument is attached to the implant assemblies, forces applied to the instrument are translated and transferred to the implant assemblies and the vertebral body into which the implant assemblies have been inserted thereby providing a rotational force on the vertebral body.
