AO Spine Knowledge Forum Spinal Cord Injury (SCI)

A global clinical research group addressing critical knowledge gaps for SCI patients

How the AO Spine Knowledge Forum SCI improves patient care

AO Spine Knowledge Forum Spinal Cord Injury (KF SCI) is an international group of dedicated spine surgeons who seek to define new treatment approaches and address critical knowledge gaps to enhance outcomes for both traumatic and non-traumatic spinal cord injury patients by performing research projects that bring significant impact to the spine surgeon community.

They will do this by addressing the following knowledge gaps:

  • Central cord pattern of incomplete tetraplegia in the setting of a mechanically stable cervical spine: what is the role of early surgery?
  • What tools could be used to better understand and characterize a cord injury? For example, MRI, intraoperative ultrasound?
  • What is the best way of achieving decompression?
  • What additional guidelines are necessary for surgeons treating SCI patients?
  • Filling the knowledge gaps in degenerative cervical myelopathy (DCM) through the AO Spine RECODE project.

Practical tools for clinicians developed by the Knowledge Forum SCI

These selected clinical tools and papers will help clinicians in planning appropriate treatments and research projects, assessing patient progress, and providing the best evidence to support decision-making, ultimately enhancing clinical practice and outcomes for patients who have sustained a spinal cord injury.
Clinical Practice Guidelines

Guidelines for the Management of Acute Spinal Cord Injury

A new set of clinical practice guidelines has been published by the AO Spine Knowledge Forum Spinal Injury and the Praxis Spinal Cord Institute in 2024. They combine top evidence and expert opinions to offer clinicians evidence-based treatment recommendations for the following topics:

  1. The role and timing of surgical decompression after acute traumatic SCI;
  2. The hemodynamic management of acute traumatic SCI; and 
  3. The definition, diagnosis, and management of intra-operative SCI.

Clinical Practice Guidelines
 
Guidelines for the Management of Degenerative Cervical Myelopathy and Traumatic Spinal Cord Injury

In 2017, the AO Spine Knowledge Forum Spinal Cord Injury developed a set of clinical practice guidelines for the management of Degenerative Cervical Myelopathy (DCM) and Traumatic Spinal Cord to support clinicians in their decision-making. 
Clinical Practice Recommendations

The ultimate goal is to re-invigorate the multidisciplinary, global community and focus on knowledge to action strategies.

    1. ACT 1 – Teach: Education syllabus
    2. ACT 2 – Detect: Diagnostic criteria
    3. ACT 3 – Origins: Definition for patients with acute spinal cord compression (ASCC) and guidelines for how to monitor patients with ASCC or DCM not managed surgically
    4. ACT 4 – Image: Guidelines on spinal cord imaging for DCM
    5. ACT 5 – Early Recovery After Surgery (ERAS) guidelines on the perioperative management in DCM
    6. ACT 6 – Bridge: Minimum data set for preclinical research in DCM
