<p>The present invention relates to a wedge used during open type HTO surgery for orthopedics. Pain of a patient can be significantly reduced by giving slopes to multi-axis on an upper surface or a lower surface of the wedge, and reducing a period of osteanagenesis of an empty space as front and rear and left and right slopes correspond when applying to a complex empty space formed by neck bone surgery. Also, the present invention can overcome the difference in shapes of the empty spaces which are differently generated in the left and right leg by overturning the wedge.</p> |
