Clinical Expert Advice Forums

Documented expert opinion where it matters

Evidence based medicine and randomized prospective controlled trials are the basis of clinical medicine today. While we strongly rely on this evidence, the practicing surgeon frequently encounters clinical scenarios for which solutions from such trials are not possible.

The AO Spine Clinical Expert Advice Forums aims to fill that void, by documenting experts’ advice on different everyday clinical scenarios, from diagnosis, or management decisions, to intra-op events or post-operative complications.

This year’s working groups include the scenarios detailed below:
