Goals

AO Spine KF Deformity at the Global Spine Congress 2019 in Toronto, ON, Canada

AO Spine KF Deformity aims to improve the care for patients with a spinal deformity by generating and disseminating meaningful and impactful clinical evidence.

They do this by engaging leading clinicians, researchers, and spine centers from around the world to perform evidence-based research and by disseminating the research findings and newfound knowledge through publications and presentations.

Ongoing research projects

AO Spine Knowledge Forum Deformity Focus Issue

Principal investigator:

Stephen Lewis

Co-Principal investigators:

Lawrence Lenke

Goals:

Aims to provide a thorough review of the current status of adult spinal deformity surgery and highlight areas of controversy. The issue will provide guidance through the current literature and help identify future directions to help answer some of the difficulties encountered in treating this complex and highly variable disorder.
Tension Parameters in Junctional Tethers for Proximal Junctional Kyphosis (PJK)

Principal investigator:

Tim O’Connor

Co-Principal investigators:

Mary O’Hehir, Jeffrey Mullin

Goals:

Aims to determine optimal tension parameters in junctional tethers for PJK
AO Spine Comprehensive Classification of Adult Spinal Deformity (AOASD)

Principal investigator:

J Naresh-Babu

Co-Principal investigators:

Manabu Ito, Jong-Beom Park, Kenny Kwan

Goals:

Aims to develop comprehensive classification that separates patients into clinically different subgroups that require different treatment strategies

Documents:

AO Spine ASD Patient Profile
*/** Spinal Deformity Intraoperative Monitoring (SDIM)

Principal investigator:
Stephen Lewis
Co-Principal investigators:
Lawrence Lenke, Nasir Quraishi
Goals:
Aims to determine the incidence of intraoperative neuromonitoring alerts in complex, high-risk, spinal deformity surgeries and identify the events that lead to such alerts
Remark:
This project was awarded with a Standard Research Grant (2018) from the Scoliosis Research Society (SRS).

Complication Classification System of Spinal Deformity Surgery (CCS-SDS)

Principal investigator:

Sigurd Berven

Co-Principal investigators:

Lawrence Lenke, Christopher Shaffrey

Goals:

Aims to develop and validate a reliable system for categorizing and classifying various complications during and following adult spinal deformity surgery
* Evaluation of neurologic complications associated with surgical correction of adult spinal deformity (Scoli-RISK 1): five-year extension

A prospective, observational, multi-center study

Principal investigator:

Lawrence Lenke

Co-Principal investigators:

Michael Fehlings

Goals:

Aims to establish the long-term risk of neurologic deficit related to the surgical correction of adult spinal deformity and to identify characteristics associated with an increased risk of neurologic complications related to surgery at five-year postoperative

ClinicalTrials.gov Identifier: NCT02949245
* Prospective Evaluation of Elderly Deformity Surgery (PEEDS): five-year extension

A prospective observational, multicenter study

Principal investigator:

Stephen Lewis

Co-Principal investigators:

Sigurd Berven

Goals:

Aims to show an improvement in SRS-22 total score between baseline and 24 months and five years after surgery in patients at age 60 or older treated with major spinal reconstruction (spinal fusion of at least five levels) for adult spinal deformity

Documents:

Publication summary

ClinicalTrials.gov Identifier: NCT02035280

* This AO Spine-sponsored study is executed with support from the AO Innovation Translation Center (AO ITC).
