AO Spine classification systems
The AO Spine classification systems is a group of imaging morphology-based classification system, combined with clinical factors for injury of spinal trauma. It is designed to be a simple and reproducible method of describing injury patterns.
At the time of writing (Oct 2018), the 4 published classification systems are:
- AO Spine: upper cervical classification system
- AO Spine: subaxial cervical classification system
- AO Spine: thoracolumbar classification system
- AO Spine: sacral classification system
The AO Spine group is an 'international community of spine surgeons generating, distributing, and exchanging knowledge to advance science and the spine care profession through research, education, and community development. With this collaborative approach, AO Spine continues to advance spine care worldwide' 2.
