AOSpine Knowledge Forum Deformity

The AOSpine KF Deformity is an international working group composed of 10 steering committee members who meet on a regular basis to discuss research, assess the best evidence for current practices, and formulate clinical studies in the domain of spinal deformities. It is charged with conducting clinical research, developing AOSpine classifications, guidelines, and outcome measures.

Project overview

Status: Planning
​Project Title ​Investigator(s) ​Aim Outcomes
Scoli-RISK-1:
5-year extension
Evaluation of neurologic compli-cations associated with surgical correction of adult spinal defor¬mity (Scoli-RISK 1): a prospective, observational, multi-center study ​PI: Lawrence Lenke
Co-PI: Michael Fehlings

To establish the long term risk of neurologic deficit related to surgical correction of adult spinal deformity and to identify characteristics associated with increased risk of neurologic complications related to the surgery at 5-year postoperative.

​CCS-SDS ​Complication Classification System of Spinal Deformity Surgery (CCS-SDS) ​PI: Sigurd Berven
Co-PI: Lawrence Lenke, Christopher Shaffrey

​To develop and validate a reliable system for categorizing and classifying various complications during and following adult spinal deformity surgery.

Status: Executing​ ​ ​ ​
​Project Title ​Investigator(s) ​Aim Outcomes
FLEXIS ​FLEXIbility in Scoliosis (FLEXIS): Comparison of dynamic radiographs in determining fusion level in adolescent idiopathic scoliosis correction
PI: Kenny Kwan
Co-PI: Kenneth Cheung, Ahmet Alanay

To identify the dynamic radiograph(s) that can most accurately predict the curve behavior after surgical correction in patients diagnosed with adolescent idiopathic scoliosis.



PEEDS &
PEEDS: 5-year extension
​Prospective Evaluation of Elderly Deformity Surgery (PEEDS): a prospective observational, multicenter study ​PI: Stephen Lewis
Co-PI: Sigurd Berven

​To show an improvement in SRS-22 total score between baseline and 24 months and 5 years after surgery in patients at age 60 or older treated with major spinal reconstruction (spinal fusion of at least 5 levels) for adult spinal deformity.

Publication summary
​ASD Consensus ​An international consensus on the appropriate treatment for adults with spinal deformity ​PI: Sigurd Berven
Co-PI: Marinus de Kleuver

​To identify goals of care and management strategies that are appropriate for adult spinal deformity patients based upon worldwide expert opinion.

Status: Completed ​ ​ ​ ​
​Project Title ​Investigator(s) ​Aim Outcomes

PI: Marinus de Kleuver
Co-PI: Manabu Ito
