AO Spine Classification Systems

AOSpine Injury Classification Systems

 

The AO Spine Knowledge Forum Trauma was given the task to develop and validate a new classification system. The AO Spine Thoracolumbar and Subaxial Classification systems are the result of a systematic assessment and revision of the Magerl classification. The AO Spine Classification Group reached a consensus on a classification that incorporates both fracture morphology and clinical factors relevant for clinical decision making. After the endorsement of the classification by the International Board, the Knowledge Forum Trauma finalized the validation studies.

Spinal lnstability Neoplastic Score (SINS)

SINS is a classification system for tumor-related spinal instability. The tool facilitates appropriate surgical referral of patients. It is highly reliable, reproducible, and a valid assessment tool to address a key question in patients with metastatic spine disease: is the spine "stable" or is there "current or possible instability" that warrants surgical assessment?

It has been validated in spine surgeons, radiation oncologists, radiologists, and spine fellows and residents.
