Filter by:Parathyroid (PTH) hormone has been shown to enhance fracture healing in animal studies. There are so far only three published papers concerning humans. Postero-lateral fusions have shown a healing rate of less than 50% after bone. The purpose of this study is to determine if PTH 1-34 (teriparatide) improves the healing rate and the clinical course after spinal stenosis surgery.
The purpose of this study is to determine safety and effectiveness, as measured by changes in pain, disability, patient satisfaction, and claudicatory symptoms, at 6 months following treatment with the Totalis™ Direct Decompression System or Sham Comparator Surgical Procedure in patients with lumbar spinal stenosis
The purpose of this study is to compare the effect and safety of NuCel to DBX on patients undergoing posteriolateral lumbar spinal fusions for degenerative disc disease.
The purpose of this study is to evaluate fusion status and patient outcomes observed from use of the VESUVIUS Demineralized Fibers with the EVEREST Spinal System as compared to the literature reported outcomes of spinal fusion using autograft with posterior stabilization.
Hypothesis: Topical application of Tranexamic acid into the surgical wound during spine surgery will decrease the overall blood loss post-operatively. This reduction in blood loss will reduce the need for transfusion. In addition it will also significantly reduce the cost of the surgical procedure. Specific Aim 1: The goal of this study is to quantitatively assess whether topical application of tranexamic acid placed into the surgical wound during lumbar spine surgery will decrease post-operative blood loss, thus lowering the need for blood transfusions. By reducing the number of transfusions participants can avoid the well-known complications associated with them. The investigators do not plan on measuring serum tranexamic acid levels. Several meta-analyses and level I studies have shown that intravenous (IV) administration of tranexamic acid is effective in reducing postoperative blood loss and the need for transfusion.
The purpose of this study is to evaluate the safety and efficacy of CarboFix' Pedicle Screw System in the lumbar spine.
The purpose of this study is to determine whether NuCel is effective in promoting spinal fusion in degenerative disease of the lumbar spine.
Lumbar Spinal Stenosis (LSS) is a clinical entity were narrowing of the spinal canal gives a compression of the the neural and vascular structures in the spinal canal. This often gives neurogenic claudication and sometimes severe Low Back Pain (LBP). Surgery for LSS is today the most often performed procedure in the adult lumbar spine. Beneficial effect of surgical treatment is well documented by several clinical trials, and a Cochrane review article from 2005 concludes that surgical treatment is superior to non-surgical treatment. The surgical solution is to decompress the stenotic part of the lumbar spine. There is no consensus in the literature of which surgical method that gives best long term clinical results. The investigators are therefore planning a Randomized Controlled Trial, where they will compare clinical and radiological results of three different surgical methods for LSS. The main outcome of this study is to answer which surgical method that gives the best long term clinical results. And, secondary outcome is to find out how much increase of the Dural Sac Cross Sectional Area is needed to give a long time relief of the patients` symptoms.
Introduction: This observational study is designed to test the equivalence between the clinical effectiveness of microdecompression and laminectomy in the surgical treatment of central lumbar spinal stenosis. Lumbar spinal stenosis is the most frequent indication for spinal surgery in the elderly, and as the oldest segment of the population continues to grow its prevalence is likely to increase. However, data on surgical outcomes are limited. Open or wide decompressive laminectomy, often combined with medial facetectomy and foraminotomy, was formerly the standard treatment. In recent years a growing tendency towards less invasive decompressive procedures has emerged. Many spine surgeons today perform microdecompression for central lumbar spinal stenosis. Prospectively registered treatment and outcome data are obtained from the Norwegian Registry for Spine Surgery (NORspine).
The purpose of this study is to assess lumbar fusion using nanOss Bioactive bone void filler
