with spinal stenosis undergoing back surgery with the coflex® implant, and to look at their
outcomes and the cost-effectiveness of this procedure.


Inclusion Criteria:

1. Patient is skeletally mature and has at least moderate impairment in function,
experiences relief in flexion from his/her symptoms of leg/buttocks/groin pain, with
or without back pain, and has undergone at least 6 months of non-operative treatment;

2. Radiographically compromised vertebral bodies at any lumbar level(s) caused by current
