Randomized Controlled Trial Comparative Study
[Clinical study on unilateral pedicle screw fixation and interbody fusion for the treatment of lumbar degenerative diseases under Quadrant system].
To compare the clinical effects of unilateral pedicle screw fixation (uni-PS) assisted by Quadrant system and bilateral pedicle screw fixation (bi-PS) for the treatment of lumbar degenerative diseases. ⋯ Minimally invasive unilateral pedicle screw fixation is a safe and feasible method for the treatment of lumbar degenerative diseases. It is as effective as the bilateral fixation in lumbar spinal fusion. In addition, it has the advantages of short operative time, less volume of blood loss, high fusion rate, etc.

To investigate the clinical effects of spinal canal decompression and pedicle screw reduction and fixation, and intervertebral bone grafting fusion for the treatment of lumbar spondylolisthesis associated with nerve compression symptoms. ⋯ Postlaminectomy reconstruction of the vertebral lamina and pedicle screw reduction and fixation can achieve satisfactory reduction and spine biomechanical stability in the treatment of lumbar spondylolisthesis, and can prevent latrogenic stenosis of the vertebral canal due to nerve oppression by the postoperative scar and nerve adhesion, with good early and medium-term curative effects. In addition, it provides a new way of thinking in the treatment of lumbar spondylolis-thesis.

To investigate the clinical effects of limited decomression, fixation, and fusion in treating degenerative scoliosis with spinal stennosis. ⋯ Surgical treatment with limited decompression, pedicle screw fixation and fusion is effective method for degenerative scoliosis with spinal stenosis, individualized surgery design should be made according to clinical symptoms, signs and imaging features.
-
To investigate the surgical outcomes of unilateral lumbar pedicle screw fixation and intervertebral body fusion in treating far lateral lumber disc herniation. ⋯ Unilateral lumbar pedicle screw fixation and intervertebral body fusion could increase the initial stability after fusion, restore and maintain the intervertebral height, and elevate the improvement rate in treating far lateral lumber disc herniation. The surgical method is safe, effective and reliable, but need to strictly control indications.
