The vast majority of patients with ischemic low-grade spondylolisthesis is clinically asymptomatic. Failure of conservative procedures indicates surgical treatment.
The basic pillar of surgical care is instrumented spondylodesis, with or without decompression. In our retrospective study of prospectively collected data, we present a group of 22 patients with low-grade isthmic spondylolisthesis treated primarily by posterior reduction and fusion of the affected segment without decompression of the spinal canal with subsequent anterior interbody fusion autografts.
