MiDura-Study (Neuro-Patch in Duraplasty)

The aim of this study is to collect systematically and proactively data regarding the performance of Neuro-Patch, like complications and handling, under daily clinical practice when used as intended by the manufacturer

Understanding How Methadone Treatment During Surgery Affects Pain Levels and the Need for Pain Medications After Surgery

The researchers are doing this study to find out whether giving methadone during spinal surgery helps manage pain in the first 72 hours after surgery better than other standard pain medications. Participants' pain will be measured by how much pain is reported after surgery, and how much additional pain medication is needed to lower pain levels. The researchers will look at whether giving methadone during surgery reduces the need for other pain medications after surgery. In addition, the team will compare the effects of the two standard treatments- one with methadone and one without methadone to to evaluate which one works best.

Methadone to Reduce Chronic Opioid Use After Major Spine Surgery: The MEND Pilot Feasibility Study

The investigators propose a randomized, triple-blinded (patients, investigators, outcomes assessors), placebo-controlled pilot feasibility trial (Methadone to End Narcotic Dependence, MEND trial) to assess the feasibility and safety of postoperative oral methadone in patients undergoing spine surgery and collect preliminary data to inform a larger clinical trial that will test the opioid-sparing effects of methadone at 3 months after spine surgery.

Staircase Nutritional Intervention for Elderly Patients Undergoing Spinal Fusion Surgery

The goal of this prospective multicenter randomized controlled clinical trial is to evaluate the efficacy of a staircase nutritional intervention in reducing postoperative complications and improving long-term functional recovery in elderly patients aged ≥75 years scheduled for spinal fusion surgery. The main questions it aims to answer are: 1. Does the staircase nutritional intervention reduce the 30-day postoperative complication rate, as measured by the Comprehensive Complication Index (CCI), compared to conventional ERAS diet management? 2. Does the staircase nutritional intervention improve 1-year functional recovery, as assessed by Oswestry/Neck Disability Index (ODI/NDI) and health-related quality of life (EQ-5D), compared to conventional ERAS diet management? Researchers will compare the intervention group receiving MNA - based staircase nutritional intervention (including 14-day preadmission oral nutritional supplementation, perioperative personalized nutritional support, and postdischarge continuous management) combined with surgery-specific prehabilitation training to the control group receiving conventional ERAS diet management to see if the former leads to better clinical outcomes and long-term functional recovery. Participants will Undergo randomization: Be randomly assigned to either the intervention group or the control group. Receive assigned interventions: Control group: Receive conventional ERAS diet management, including preadmission nutritional education and early postoperative oral intake. Intervention group: Undergo MNA - based staircase nutritional intervention and surgery-specific prehabilitation training. Participate in follow-up: Complete short-term (within 90 days postoperatively) and long-term (6 and 12 months postoperatively) follow-up assessments, including laboratory tests, functional evaluations, and satisfaction surveys.

Correlation Analysis of POD and pNCD in Elderly Spinal Surgery Patients

This study is a prospective cohort study to investigate the differences in serum indexes between elderly spinal surgery patients with postoperative delirium (POD) who either develop or do not develop long-term postoperative neurocognitive disorders (pNCD).

Perioperative Rectal Methadone in Spine Surgery

Patients undergoing spinal surgery require pain control medication after their surgery. Investigators have successfully used intravenous Methadone to manage pain after surgery. However, doctors in Canada do not have the intravenous form of Methadone to prescribe to their patients. The investigators in Canada propose a pilot trial to investigate whether Methadone administered rectally could be used to manage pain after spinal surgery. The main questions are: 1. Are investigators able to recruit participants for this trial and learn from this study to plan a larger trial? 2. Does Methadone administered rectally during surgery, reduce participants' pain intensity, use less pain medication, and have a better recovery after surgery? Investigators will compare Methadone to a placebo (a look-alike substance that contains no drug) to see if Methadone works to manage pain after surgery better than the usual pain management. Participants will: * receive either Methadone or placebo during surgery. * be asked some questions about their pain during days 1 to 3 after surgery * be contacted by phone to ask about their recovery At this time, the study aims to recruit 40 participants from St. Michael's Hospital, to learn whether it will be feasible to plan a larger study.

Effects of Three Different Methods Applied to Patients After Spine Surgery on Nausea, Thirst and Comfort

The aim of this study was to determine the effects of postoperative methods on nausea, thirst and comfort levels of patients undergoing spinal surgery.

Esketamine on Postoperative Sleep Disturbance of Patients Undergoing Spinal Surgery

The goal of this clinical trial is to learn about the effect of intraoperative esketamine infusion on postoperative sleep disturbance(PSD) of patients undergoing spinal surgery. The main aims to answer are: * To explore the effect of intraoperative infusion of esketamine on the incidence of postoperative sleep disturbance and sleep quality in patients undergoing spinal surgery. * To explore the effect of intraoperative infusion of esketamine on postoperative pain, anxiety and depression ; Participants will be patients undergoing spinal surgery with general anesthesia at Beijing Tiantan Hospital. 0.3mg/kg/h esketamine or saline will be infused during surgery . The incidence of sleep disturbance , sleep quality, pain scores, hospital anxiety and depression scores and perioperative adverse events after surgery will be investigated.

Study Comparing Arthrodesis Technique of Thoracic and/or Lumbar Spine by Posterior Approach Performed by Robot-assisted Surgery (Robot Mazor X Stealth ™) Versus Conventional Surgery

Osteosynthesis by pedicle screwing is the reference technique since the 1980s, due to the quality of the mechanical grip of the screw in the pedicle, despite difficulties of placing the implant in this narrow tunnel. This precision was improved by fluoroscopy, then by navigation, which made it possible to reduce the extra-pedicular placement of the screws and consequently the complications. Since the 2000s, robotic has been developed in all areas, including medicine and surgery, (Da Vinci robot in urology) and several robots are currently marketed for spinal surgery, Medtronic's Mazor X Stealth ™ robot being the most successful. The aim of this study is to evaluate on a prospective randomized comparative study the quality of the placement of the screws as well as the occurrence of complications, the clinical results and the medico-economic interest that robotic surgery can bring.
