In the surgical treatment of various types of spinal stenosis, adequate decompression of the nerve roots and maintenance of spinal stability are essential. When spinal instability or degenerative spinal malalignment exists, extensive laminectomy impairs the mechanical integrity of the posterior supportive structures, and acceleration of the spinal instability and symptom recurrence may occur.
