Patient’s feedback at the time of the follow-ups:

1 week after treatment: Overall symptoms have eased. Calf pain and numbness are nearly gone.

1 month after treatment: Condition remained the same as at one week, with no new symptoms.

3 months after treatment: Experienced some lower back pain when sitting, but otherwise able to live normally.

6 months after treatment: Condition has remained the same since improvement, with no recurrence of major symptoms.

The symptoms of spinal canal stenosis of this patient have yet to reappear more than one year after treatment.

Concerning residual symptoms, causes other than the disc itself are possible.

Since pain does not occur when posture is corrected, bone-related factors may be involved.

The patient has been making efforts to correct his posture whenever pain occurs, thereby preventing symptoms from reappearing.

* Note:

Results vary among individuals. Please be aware that identical outcomes cannot be guaranteed.

It generally takes 3 weeks to 3 months for treatment effects to appear.

Our Treatment Method

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.
