SIJ surgery

The missing therapeutical link?

Since 2009 thirteen new SIJ fusion systems were presented which raises huge expectations for the medical device industry and for patients. SIMEG is not recommending or prefering any technique, efficacy needs to be approved by appropriate clinical studys (see our study page). The development of an international register to collect the product features is duscussed. Basically there are three SIJ fusion principles:

1. Posterolateral approach: Mechanical primary stabilization utilizing one or more percutanous, transgluteal screws or dowels transfixing the ilial and sacral bone for secondary arthrodesis.

 

 

2. Posterior approach: Transfixing dorsolateral technique like (1) with our without additional bonegrafting.

3. Posteromedial: Distraction of the joint space and realignment of the dislocated articular surfaces primary fusion with temporary mechanical immobilisation in mini-open technique via a posterior midline approach. 

Non-surgical treatment is mandadory prior to considering surgery. A consensus about the definition 'end of therapy' should be found.
