Spinal implants or instrumentation have been used for many years for the re-alignment and stabilization of unstable or deformed spine. A pedicle screw is a particular type of bone screw designed for implementation into vertebral pedicle. These screws are used to correct deformity or treat trauma and also are used to immobilize part of spine to assist fusion by holding vertebrae together. Over the years, pedicle fixation systems have proved to be biomechanically superior for segmental fixation. Thus, numerous systems and variations are being developed.
