Degenerative spondylolisthesis with spinal stenosis is common in elderly patients. When symptomatic, the resultant neurogenic claudication often leads to a diminished quality of life. A nonsurgical approach is an appropriate first step. Maximizing the chance of a solid arthrodesis improves the possibility of a successful long-term outcome. Treatment of this ...
