Interbody vs Instrumented Posterolateral Fusion Following Decompression for Lumbar Spinal Stenosis...
Degenerative SpondylolisthesisSpinal StenosisDegenerative spondylolisthesis describes the slip of one spinal segment relative to the adjacent segment. It is usually associated with spinal stenosis (which limits one's ability to walk and stand) and is the most common indication for surgery in adults over age 65 years. A variety of surgical techniques are available; the most common are the Posterolateral Instrumented Fusion (PLF), and Interbody Fusion (IF) including Posterolateral Interbody Fusion (PLIF), and Transforaminal Interbody fusion (TLIF). IF uses a cage that is placed within the cleaned out disc space between the vertebral bodies being fused. Although this approach achieves a good fusion rate and deformity correction it is associated with a higher surgical cost and potential intra-operative complication rate. What is more, no consensus exists as to whether IF provides better patient rated functional outcome and quality of life. If the advantages of IF do not translate into superior patient rated outcomes, then the risk-benefit ratio would be tipped in favor of PLF. The purpose of this study is to determine if IF is equivalent to PLF for the treatment of degenerative spondylolisthesis. The investigators will conduct a prospective randomized control trial comparing these two procedures. Our primary outcome measure will be the Oswestry Disability Index, which evaluates spinal pain and function.

Clinical Effect of Preventive Use of Tylenol on Fever After Removal of Drainage Tube in Lumbar Fusion...
Lumbar Spinal StenosisLumbar Disc Herniation1 moreThis study evaluates the influence of Non-steroidal Anti-inflammatory Drugs on preventing fever after the removal of drainage tube in the patients who suffered lumbar fusion surgery, if the outcome turn out positive, the preventive use of non-steroidal anti-inflammatory drugs could decrease the possibility of fever happening when we remove the tube.
The Spinal Stenosis Pedometer and Nutrition e-Health Lifestyle Intervention (SSPANLI) Trial
Lumbar Spinal StenosisObesityObesity is one of the most important determinants of quality of life and function. People with lumbar spinal stenosis may be at increased risk of obesity given walking limitations. Spinal stenosis is a very common degenerative condition in people over 45. People with this condition have pain and numbness in the legs during walking, and therefore avoid physical activity. Lack of physical activity is related to weight gain and increased risk of chronic disease. Objective: The objective of this project is test a new e-health (online) pedometer and nutrition intervention aimed at promoting weight loss and increasing physical activity in overweight and obese individuals with spinal stenosis. Methods: The investigators will recruit 88 people with lumbar spinal stenosis who are overweight or obese. Half of these people will receive the 12-week intervention, and the other half will receive usual care (no intervention). In Weeks 1 and 6, people in the intervention group will meet with a Registered Dietitian and an Exercise Physiologist for personalized sessions. They will receive a pedometer and instructions on how to log in to the e-health site (https://sspanli.mtroyal.ca). They will wear the pedometer daily and log in to the website each week for a nutrition education session, a weekly step goal, and tips. The investigators will look to see whether people in the intervention group show greater change in physical activity, body composition and quality of life compared to the individuals who received usual care. Relevance: The increasing number of people with spinal stenosis represents a huge health care burden in Canada. This intervention could provide a new treatment option that would increase mobility, quality of life, and potentially alleviate the need for expensive treatments like surgery. E-health interventions provide an opportunity for patients to take an active role in their own health, and promote behaviour changes that will result in healthier Canadians less likely to access care in the future.

Erector Spinae Plane Block After Lumbar Spinal Stenosis Surgery
Lumbar Spinal StenosisErector Spinae Plane BlockLumbar spinae stenosis surgery is a frequent intervention resulting in important postoperative pain. Management of this postoperative pain is thus important. Different pain management therapies exist. The erector spinae plane (ESP) block was described in 2016. It involves the injection of local anesthetics into the interfascial plane, deep to erector spinae muscle, allowing the blockade of the dorsal and ventral rami of the thoracic spinal nerves. It was initially proposed for analgesia of costal fractures, pulmonary lobectomy and thoracic vertebrae. The ESP block (ESPB) could probably be extended to a large number of surgical procedures. ESPB has so far not been investigated in lumbar spinae stenosis surgery.
Spondylolisthesis Treated With an iO-Flex® System Enabled Decompression
RadiculopathySpondylolisthesis1 moreThe purpose of this study is to evaluate the clinical performance of a decompression using the FDA cleared iO-Flex® System on-label in treating patients with spinal stenosis and stable grade I degenerative lumbar spondylolisthesis using a precision estimate assuming a 55% positive response rate.
Head-neck Coordination Analysis After Minimally Invasive Surgery in the Dorsal Cervical Spine
Multilevel Cervical Spinal StenosisSingle Brachial RadiculopathyTo proof patients' benefit of minimally invasive surgery in the dorsal cervical spine an apparatus to examine head-neck-coordination was constructed. Two different surgical techniques will be compared: Laminoplasty: open approach vs minimally invasive surgery (MIS)-approach; Foraminotomy: open approach vs MIS-approach. Each patient will be tested before surgery, postoperative as well as 3 and 12 month follow-up. Hypothesis is that patients after MIS-approaches perform better in their head-neck-coordination as patients with open approaches.
Prone or Supine Extubation in Lomber Spinal Surgery
Lumbar Spinal StenosisThe aim of this study was to investigate the emergence quality of patients extubated on prone or supine position after lumbar spinal surgery. 60 patients with ASA I-II who underwent lumbar spinal surgery between 18-65 years of age were included in the study. Patients with difficult intubation, BMI> 35kg / m2, asthma and reactive airway problems, cardiovascular disease and obstructive sleep apnea will not be included in the study. Initial data will be recorded after standard monitorization. Induction is made by 2 mg / kg propofol, 1 mg / kg fentanyl and 0.5 mg / kg rocuronium will be added for muscle relaxation. Patients with adequate muscle relaxation will be intubated with appropriate endotracheal tube and mechanical ventilation will be initiated. Patients who are then given prone positions on the operating table will be supported with side gels. The head will be placed in the face gel in a neutral position. For intraoperative analgesia, remifentanil infusion at 0.2mcg / kg / min will be applied. After laminectomy is completed and control of bleeding, 1 mg / kg Tramalol and 2 mg / kg Metaclopromide will be applied to all patients. At the end of the skin stitching, the inhalation agent will be closed and the fresh gas will be turned 6 lt 100% O2. Patients who want to be extubated in the prone position are left in this position while the other patients will be placed on the stretcher in a supine position for a short time. Patients will be decurarized be neostigmin with atropine. Extubation will be performed in both positions when spontanous ventilation begins at a tidal volume of 6ml / kg and a frequency of 12-20 / min. All the measures will be taken to ensure airway safety while the patient is extubated pron. The stretcher will be brought to the side of the operating table, investigator will be ready for reintubation and all the necessary persons will be with the patient. Aspiration frequency will be recorded for each patient. During recovery after extubation, the severity of cough will be evaluated as mild (only once), less (more than one but not continuous) and severe (continuously for 5 seconds). Aldrate scores of patient will be recorded and first 9-10 time is estimated from extubation time. Vomiting, nausea, respiratory insufficiency, inability to control the airway and obvious desaturation if seen are also recorded.
