“…In this study, there were 3 cases (16.7%) of postoperative instability found in the 'Interspinous U' patient group and 1 case (14.3%) found in the 'DIAM' patient group. In the meantime, there were 3 cases (16.7%) of re-operation in the 'Interspinous U' group and 2 cases (28.6%) observed in the 'DIAM' group, which shows a negative result, compared to the previous researches on PDS, and shows a higher ratio than 12% of re-operation from the research on the longterm prognoses of patients on whom pedicle screw fusion was performed, conducted by Shin et al 15) .…”

ObjectivesRecently posterior dynamic stabilizations (PDS) are increased in degenerative lumbar disease. But, some previous studies had doubts its long term prognosis. Long term clinical and radiological results of PDS using interspinous device (Interspinous U, DIAM) were analyzed.MethodsWe have used the 'interspinous U' and 'DIAM' for patients with lumbar spinal stenosis. We included single level lumbar spinal stenosis patients who completed minimum 60 months follow-up evaluation. All patients checked plain lateral and flexion-extension views at immediately after the surgery and each follow-up. The clinical outcome was measured by Odom's criteria. Complications including post operative infection, bony erosion, device fracture, device malformations, and instabilities were surveyed.ResultsWe included 18 for 'Interspinous U' and 7 patients 'DIAM' groups. Mean follow-up durations for 'Interspinous U' and 'DIAM' were 74.6 and 62.6 months, respectively. Satisfactory groups were 50.0% and 42.9 % for 'Interspinous U' and 'DIAM' groups. In 'Interspinous U' group disc height ratio increased transiently in immediate postoperative period (from 0.18 to 0.21) and then, decreased significantly in last follow-up (0.18). In 'DIAM' group, disc height ratio increased transiently in immediate postoperative period (from 0.18 to 0.19), and then decreased significantly in the last follow-up (0.16). Three (16.7%) and two (28.6%) patients undergo on a re-operation due to severe back pain in 'Interspinous U' and 'DIAM' groups.ConclusionLong term follow up 'Interspinous U' and 'DIAM' group showed low patient satisfaction and poor radiological outcomes. To ascertain the benefit of PDS compare with posterior screw fixation, prospective analysis with larger population and multi-center study will be needed.

“…They showed that the posterior lumbar interbody fusion produces excellent clinical outcomes if the preoperative instability is of a greater degree. Shin et al 17 performed a follow-up over a 10-year period of 44 cases in whom lumbar interbody fusion was performed for the treatment of degenerative lumbar disease. According to these authors, pedicle screw loosening and breakage occurred in three cases.…”

Study DesignA retrospective study.PurposeAn en bloc partial laminectomy and posterior lumbar interbody fusion (PLIF) in spinal stenosis patients with severe foraminal narrowing has a shorter operation time, less neural manipulation and allows indirect decompression by restoring the interforaminal height compared to other procedures. This study investigated the efficacy of the procedure.Overview of LiteraturePLIF is one of the most popular surgery for degenerative spine such as foraminal spinal stenosis, instability spondylolisthesis and discogenic pain. Various techniques for PLIF have their own advantages and disadvantages. But in some severe cases, we need an efficient method of PLIF for decompression and fusion.MethodsThis study examined 61 patients, who had 85 levels treated with PLIF using an en bloc partial laminectomy and facetectomy, and could be followed up for more than 2 years. The mean age of the patients and mean follow up period was 66 years and 39 months, respectively. The clinical results were evaluated using the MacNab's criteria, Visual Analogue Scale (VAS) score, and Korea Version Oswestry Disability Index (KODI). The union of the intervertebral space was evaluated using Lenke's criteria. The intervertebral angle and height of the posterior intervertebral disc were also measured.ResultsExcellent and good results were obtained in 54 cases (89%) according to MacNab's criteria. The VAS and KODI scores were 8.1 and 34.6, preoperatively, and 3.4, and 14.1, postoperatively. Bone union was A and B grades according to Lenke's criteria in 57 cases. The mean segmental angle and mean height of the posterior disc were respectively, 7.4° and 6.5 mm preoperatively, 9.1° and 10.6 mm postoperatively, and 8.0° and 9.7 mm in the last follow-up. There were 5 cases of postoperative infection, 4 cases of junctional problems and 1 case of screw malposition.ConclusionsEn bloc partial laminectomy and PLIF is an effective method for treating severe spinal stenosis with foraminal narrowing.
