High-grade spondylolisthesis (HGS), however, is much less frequent, which makes it difficult to develop a general recommendation for its treatment. Posterior transdiscal fixation was proposed in 1994 for HGS, and the use of spine navigation could make this technique more accessible and reduce the morbidity associated with the procedure. The purpose of this study was to present a case series involving adult patients with HGS and correct spinal alignment who were treated with transdiscal pedicle screw placement guided with neuronavigation and compare the results to those achieved previously without image guidance.<\/jats:p>\n <\/jats:sec>\n \n METHODS<\/jats:title>\n The authors reviewed all cases in which adult patients with correct spinal alignment were treated for HGS with posterior transdiscal instrumentation placement guided with navigation between 2014 and 2016 at their institution. The authors compared preoperative and postoperative spinopelvic parameters on standing radiographs as well as Oswestry Disability Index (ODI) scores and visual analog scale (VAS) scores for low-back pain. Follow-up CT and MRI studies and postoperative radiographs were evaluated to identify any screw malplacement or instrumentation failure. Any other intraoperative or postoperative complications were also recorded.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n Eight patients underwent posterior transdiscal navigated instrumentation placement during this period, with a mean duration of follow-up of 16 months (range 9\u201324 months). Six of the patients presented with Meyerding grade III spondylolisthesis and 2 with Meyerding grade IV. In 5 cases, L4\u2013S1 instrumentation was placed, while in the other 3 cases, surgery consisted of transdiscal L5\u2013S1 fixation. There was no significant difference between preoperative and postoperative spinopelvic parameters. However, there was a statistically significant improvement in the mean VAS score for low-back pain (6.5 \u00b1 1.5 vs 4 \u00b1 1.7) and the mean ODI score (49.2 \u00b1 19.4 vs 37.7 \u00b1 22) (p = 0.01 and p = 0.012, respectively). Six patients reduced their use of pain medication. There were no intraoperative or postoperative complications during the hospital stay, and as of the most recent follow-up, no complications related to pseudarthrosis or hardware failure had been observed.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS<\/jats:title>\n Treatment with posterior transdiscal pedicle screws with in situ fusion achieved good clinical and radiological outcomes in patients with HGS and good sagittal spinal balance. The use of navigation and image guidance was associated with improved results in this technique, including a reduction in postoperative and intraoperative complications related to screw malplacement, pseudarthrosis, and instrumentation failure.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2017.10.focus17557","type":"journal-article","created":{"date-parts":[[2018,1,1]],"date-time":"2018-01-01T03:36:42Z","timestamp":1514777802000},"page":"E9","source":"Crossref","is-referenced-by-count":11,"title":["Image guidance in transdiscal fixation for high-grade spondylolisthesis in adults with correct spinal balance"],"prefix":"10.3171","volume":"44","author":[{"given":"Juan","family":"Delgado-Fern\u00e1ndez","sequence":"first","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University Hospital La Princesa, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paloma","family":"Pulido","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University Hospital La Princesa, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda \u00c1ngeles","family":"Garc\u00eda-Pallero","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University Hospital La Princesa, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillermo","family":"Blasco","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University Hospital La Princesa, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia","family":"Frade-Porto","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University Hospital La Princesa, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafael G.","family":"Sola","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, University Hospital La Princesa, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Spine (Phila Pa 1976)","first-page":"710","article-title":"Pedicular transvertebral screw fixation of the lumbosacral spine in spondylolisthesis.
