We reported a rare case of severe OPLL in an adult case of vitamin-D resistant rickets.
The case was 56-year-old female. We started 50-150 thousand units of vitamin-D treatment about 16 years ago.
About 2 years before operation, she was complaint of gait disturbance and dysuria.
X-ray examination showed a severe OPLL from C1 to Th2 (max. stenosis 79%, C1, 2).
We performed a surgery of canal-expansive laminoplasty and suboccipital craniectomy.
