Filter by:Different procedure of percutaneous endoscopic lumbar discectomy (PELD) was with ventral decompression of dural sac on the lumbar spinal stenosis remains unkonwn.The traditional transforaminal endoscopic spine system (TESSYS) of PELD has been used in clnical for many years, but cannot achieve dorsal decompression. A newly developed modified TESSYS procedure, "U" route PELD combining ventral and dorsal decompression was introduced. Nevertheless, the superior between TESSYS and "U" route PELD procedures on treating LSS remains unknown. This study is desinged to recruit degenerative lumbar spinal stenosis patients who underwent TESSYS or "U" rout PELD, recruited from January 2014 to December 2017. These patients will be followed up for 2 years, and assessed the minimum dura sac cross sectional area (mDCSA) by MRI, and visual analogue scale (VAS) and Oswestry Disability Index (ODI) at pre- and post-operation. The global clinical outcomes were evaluated using modified MacNab criteria postoperatively. Thus, comprehensively evaluate the safety and therapeutic effects of the two PELD procedures on LSS treatments.
Purpose: The incidence of surgery for Degenerative lumbar Disc Disease (DDD). According to the national spine registries in Sweden, Norway and Denmark, there is a difference in surgical incidence between these countries. The cause for this difference is not known. It may reflect a difference in incidence of lumbar disc hernia, but with a similar socio-economic and ethnical background in these countries, it is more likely that the differences are due to varying surgical indications. Comparing indications for surgery, patient reported outcome and factors predictive for outcome after surgery for lumbar disc decease in these countries could provide information about optimal indications for surgery. Hypotheses: (i) there are no differences in patient-reported outcome after surgery between these countries, (ii) there are no differences in indications for surgery between these countries and (iii), factors that predict outcome are similar in these countries. Method of research: By using data from three Nordic national spine registers, investigators will compare baseline data, indications for surgery and patient reported outcome one year after surgery for lumbar disc decease. Register based studies have advantages such as large sample sizes, reflecting real life, but they also have limitations such as lower follow-up rates than clinical trials. A non-response analysis will be performed to take this into account.
