昂贵

PMMA is the most used lesion filling at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage; Bolster for self-replacement can rebound vertebral body height, and Balloon-PKP and Sky-PKP can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used.

Germ depends on, ability of child make a clear distinction between right and wrong is poor, lack controls oneself; Educational means is drab, learning environment is as dry as a chip and drab; Guide be short of break, grooming besides study and specialty still is these, and recreational activities of the other in the life little, and the recreational place spending of and so on of such as cinema is high, your child too far behind to catch up with, bring about the child to feel the life lacks colour very, produce repugn tired thereby, it is inimical behavior even.
