Abstract
|
|
|
Lumbar spine fusion has become a widely accepted surgery for the management of spinal disorders. However, one of the disadvantages of conventional surgery is the extensive soft tissue dissection that is necessary in order to expose the anatomic landmarks for screw insertion and the fusion bed. The tissue injury that occurs during the surgical approach can result in increased postoperative morbidity, pain, infection and impaired spinal function. Therefore, the goals of the minimally invasive spinal fusion procedure are to minimize tissue injury.
The application of percutaneous lumbar pedicle fixation techniques to the lumbar spinal diseases is theoretically sound. However, the indication and technology are currently in evolution. Although the percutaneous pedicle screw fixation technique has a logical basis and is appealing to the patient and surgeon alike, long-term studies will clearly determine their advantages compared with conventional open surgeries
