				 Dss 
 I too was wondering the logic behind the addition of the DSS.  From the CT scan and subsequent explanation from your previous post, it seems apparent that some sort of decompression would be in order.  If you don't mind elaborating, what is the logic behind the adding of more hardware to your spine?  I understand that extensive decompressions can lead to instability and a PDS device can be used to offset this potential result.  Is this the case here?
