Current National Collaboration Projects
Prospective Registry Projects
Canadian Spine Outcomes and. Research Network (CSORN) substudy: Surgical Treatment of Adult Spinal Deformity
• To identify if significant regional variation occurs in the referral pattern and surgical treatment of adult spinal deformity patients in Canada.
• To determine if specific variables independently predict the clinical outcome of surgical intervention for adult spinal deformity.
• To determine if specific variables independently predict adverse events associated with adult spinal deformity surgery.
• To determine if specific variables independently predict the radiographic outcome of surgical intervention for adult spinal deformity.
Canadian Spine Outcomes and. Research Network (CSORN) substudy: Cervical Spondylotic Myelopathy
• To determine the natural history of CSM patients selected for conservative management based on mild non progressive symptoms or patients preference not to undergo surgery
• To determine the outcomes of patients decompressed anteriorly, posteriorly and with a combined anterior/posterior approach.
• To determine differences in outcome for patients undergoing laminectomy and fusion (LF) versus laminoplasty (LP) for multi-level CSM based on a Standardized Clinical Assessment and Management Plan (SCAMP)
• To perform cost-utility analysis for different surgical and non-surgical management strategies for CSM
Canadian Spine Outcomes and. Research Network (CSORN) substudy: Prediction of Neuropathic Pain Post Cervical Compressive Myelopathy Decompressive Surgery
• The objective is to determine if the occurrence of Neuropathic Pain Post Cervical Compressive Myelopathy
Decompressive Surgery be predicted preoperatively.
• To determine the prevalence rate and effects of Neuropathic pain on patients undergoing Cervical
Compressive Myelopathy Decompressive Surgery.
Canadian Spine Outcomes and. Research Network (CSORN) substudy: Surgical Treatment of Degenerative Spondylolisthesis: A Standardized Clinical Assessment and Management Plan (SCAMPS) Canadian Spine Society (CSS) Multicentre Prospective Cohort Study
• A prospective observational study aiming to classify surgical techniques for the management of degenerative spondylolisthesis based on the stability of the pathology.
Pediatric Spine Sub Study: PERFORM
•This multicentre Canadian study will prospectively enrol pediatric patients with spinal pathology requiring surgical treatment. The Canadian Pediatric Spine Society Sub-Study PERFORM (Pediatric Registry For Spine Outcomes and Research Metrics). The objective of the PERFORM sub-study is to track specific outcome measures of different surgical techniques. Data collection will be comprised primarily of pediatric participant and physician reported outcomes.
Retrospective Registry Projects
Conus medullaris recovery in motor strength, bowel and bladder function.
•Examine factors association with neurological improvements and the recovery of the bowel and bladder sphincters in patients with Conus Medullaris Injury using the Canadian Rick Hansen Spinal Cord Injury Registry (RHSCIR) from Praxis Spine Institute.
•Determine incidence and causes of conus medullaris injuries in a Canadian population
Multi-Level Decompression/Fusions are as Effective as Single Level Lumbar Spinal Stenosis Operations
• To determine if an increase in the number of segments fused in thoracolumbar spinal fusion surgeries effects intraoperative and long-term patient outcomes.
• Collaboration with St. Michael’s Hospital’s Dr. Ahn and CSORN registry
Postoperative Recovery Patterns Following Discectomy Surgery for Lumbar Radiculopathy
• To identify the trajectories of pain and disability in patients who underwent lumbar discectomy surgery, and to investigate the construct validity of the trajectory subgroups based on clinically meaningful changes.
• Collaboration with the CSORN registry
Exploring the Impact of the Covid-19 Lockdown on Spine Surgery Patients in Canada Introduction
• Determine if the emergence of a global pandemic affected the biopsychosocial profile of patients waiting for spine surgery across Canada.
• Determine if the emergence of a global pandemic affected the biopsychosocial profile of patients in early recovery from spine surgery across Canada.
• Collaboration with the CSORN registry
Are There Gender Based Differences in Outcomes for Elective Lumbar Spine Surgery in Canada?
• The purpose of this study was to determine gender differences in the outcome for lumbar decompression, microdiscectomy, and lumbar decompression and fusion, utilizing the national CSORN registry.
• Collaboration with St. Michaels Hospital Dr. Ahn and the CSORN registry.
Preoperative depression risk is associated with unfavorable trajectories of neck and arm pain following anterior cervical discectomy and fusion
• Identify postoperative trajectories of neck and arm pain in patients undergoing ACDF.
• Investigate the associations between preoperative depression and trajectory subgroup membership.
• Collaboration with the CSORN registry.
An Examination of Life Satisfaction(LS) Following Traumatic Spinal Cord Injury induced Quadriplegia (QP) and Paraplegia (PP): Comparing Society’s Expectations to Patient reported Life Satisfaction
• To see though the general population and individuals living with QP or PP will report average or above average LS, the no paralysis group will report higher levels of LS than individuals living with paralysis.
• To determine if unaffected individuals will report lower levels of LS when asked to imagine that they are living with paralysis, as compared to their actual levels of LS.
• To determine if individuals who imagine that they are living with paralysis will report lower LS than the LS reported by individuals actually living with paralysis.
• To determine if LS associated with living with QP will be lower than LS associated with living with PP in both the real paralysis and imagined paralysis groups.
• Collaboration with the Praxis Spinal Cord Institute and the University of New Brunswick Saint John
Opioid Prescribing Patterns of Spine Surgeons in Canada: Preliminary Investigation
• To investigate the opioid and nonsteroidal anti-inflammatory drug prescribing patterns of spine surgeons in Canada
• Collaboration with the Canadian Spine Society membership and CSORN registry.
