The best way to treat a HGDS is to correct the multidirectional deformity of the lumbosacral junction with minimal neurological risks.
The advent of intraoperative 3D navigation systems permit safe and accurate instrumentation and decompression; [sup], however, there are few report available on its use in the treatment of the HGDS. The purpose of this study is to review a consecutive series of patients with high-grade dysplastic L5/S1 spondylolisthesis, who underwent posterior reduction and monosegmental fusion assisted by the intraoperative 3D navigation system, and to estimate the efficacy of this technique.
Although there is a general consensus on the need for surgical treatment of HGDS patients, the optimal surgical approach and techniques remain controversial.
A major concern in any reduction procedure of L5/S1 spondylolisthesis is injury to the L5 nerve root that ranges from 11% to 30% in the posterior reduction of HGDS. In our series, only one patient presented transient postoperative neurological deficits.
After excluding patients who had previously been designated as having "borderline or indeterminate" serrated polyp, the prevalence of SSA/P with LGD, HGD, and CRC in our cohort (7.7%, 0.59%, and 0.03%, respectively) was still lower than the reported rates in the prior study from this institution (12%, 2%, and 1%).
