Specific Indication

For patients who fail conservative treatment, but who are not
candidates for a complete laminectomy or an irreversible
procedure such as fusion, functional interlaminar implants are the
answer.

Main indication: Radiographically confirmed moderate
to severe stenosis with neural element compromise resulting
in claudication and/or radicular symptoms isolated
to 1 or 2 levels, in the region of L1 to L5 with or without
concomitant low back pain including conditions such as stable grade
1 spondylolisthesis. Interlaminar stabilization is performed after
microsurgical decompression of stenosis at the affected level(s).
The coflex™ implant may also be used in up to 2 lumbar motion
segments adjacent to fused level(s).

Research Activities

Research activities include:

Instability (rotational or vertical) associated with recurrent
herniations

Large voluminous primary disc herniations

Adjunctive therapy for stabilizing levels above or below a fusion
("topping off") in the same procedure to minimize adjacent level
degeneration.

Conjunctive therapies to be envisioned:

Combination with nucleus replacements

Combination with total disc replacements with mild to
moderate facet degeneration.
