Hello,
I am doing research to better select a artificial disc for my injured and severely degenerated L4/L5 that already has two microdisectomies in 1997 & 2014

On the safety perspective, is it true that the Activ-L has a much safer lateral anterior retroperitoneal approach option for both initial first time surgery as well as revision surgery? (Safer distance from the Veins and Artery?)

Is it true that the Activ-L is safer and easier to remove or re-position if a revision is necessary?

Is M6-L more difficult to revise?

I am no expert but I am thinking the M6 will seat better with the keel but more difficult to revise if problems occur, on the other hand the Activ-L won't fit as secure but safer to remove?

There are many good doctors using either the Activ-L and/or M6-L, but my main concern is which technique and disc is safer if I ever need a revision.

I have not come across anyone that had a problem nor revision @ L4/L5 using the Activ-L...... M6 however I did hear a few people needed revisions.

Any comments or advice is appreciated... PM me also great... Thanks!
