Supplementary Information on the Cellgel Method
Cost of the Cergel Method:
¥1,320,000 / 1 site (tax included)
to ¥1,760,000 / 5 sites (tax included)
Risks and Side Effects:
Temporary pain may occur after treatment.
Nerve injury is theoretically possible due to the nature of the procedure, but no such cases have been reported in our own experience or in published studies.
Extremely rare risk of allergic reaction to local anesthetic.
Symptoms may temporarily worsen for 1–2 weeks after treatment, believed to be due to decompression effects of the implant pulling on surrounding tissue.
If the disc is severely collapsed or nearly gone, treatment may not be possible.
The physician will discuss suitable treatment options with each patient depending on their condition.
