Decompression

The operation requires general anesthesia. First, the exact location
of the spinal canal stenosis is determined by x-ray and the skin
incision is defined. Next, the skin is incised and the muscles of the
back are pushed to either side, allowing the spinal canal to be
opened.

The next step involves decompression of the irritated nerve fibres.
This involves the surgeon removing all bone, joint, ligament or disc
segments that are narrowing the spinal canal.

Implant Selection

Once the spinal canal is widened and the nerve cords are
decompressed, the surgeon chooses the appropriate implant for
insertion. He measures the distance between the spinous processes
with a test implant and determines the correct size of implant
needed.

Implant Insertion

The coflex™ implant is inserted between the adjacent spinous
processes providing a close fit.

Once decompression of the irritated nerve fibres is complete, the
coflex™ implant will permanently stabilize the spinal column.
Maintenance of function is now ensured.

What happens after the operation?

Although the pain in one’s back and at the wound site after surgery
can be uncomfortable, there are good pain remedies available that
will usually relieve the discomfort.

The implant is immediately ready to bear weight and it also
stabilizes the spinal column. You will usually be able to stand up
immediately after the operation.

During the first weeks after surgery you should generally avoid
severe stress on the spine through heavy lifting, twisting and/or
leaning backwards. This will speed up the healing process for the
implant.
