Therefore, the fixing tool is closely fixed to a tibia, which has been cut open due to a procedure of a high tibial osteotomy, thereby enabling solid union of the tibia. ## Claims ### Claim 1 A fixing tool for an open-wedge high tibial osteotomy, which is adapted to be installed on a tibia cut open due to an open-wedge tibial osteotomy, the fixing tool comprising: a fixing plate which includes a head portion that has a plurality of nut holes, and an elongated plate portion that has a plurality of nut holes and a long hole and is formed to protrude from one side of the head portion; screws which are coupled to the nut holes; and a block which is detachably installed by the long hole by using a fixing screw, the block having two tapered protrusions protruding from a body of the block, wherein the tapered protrusions are tapered along a distal facing surface of the protrusions so that a first side of the distal facing surface is thicker than a second side of the distal facing surface. ### Claim 2 (depends on 1) The fixing tool of claim 1, wherein the head portion has a predetermined curvature. ### Claim 3 (depends on 2) The fixing tool of claim 2, wherein the screws installed in the head portion are inclined toward a center of the curvature. ### Claim 4 (depends on 2) The fixing tool of claim 2, wherein tips of the screws, which are installed toward a centerline that connects a center of the head portion and a center of the curvature, and installed at opposing sides of the center of the head portion, are spaced apart from the centerline. ### Claim 5 (depends on 1) The fixing tool of claim 1, wherein the nut hole formed in the head portion is inclinedly formed to have a gradient of 8 to 12 degrees in a direction toward the elongated plate portion. ### Claim 6 (depends on 1) The fixing tool of claim 1, wherein an opposite side of the head portion is inclined at an inclination angle with respect to a longitudinal axis of the elongated plate portion. ### Claim 7 (depends on 6) The fixing tool of claim 6, wherein the inclination angle is 5 to 7 degrees. ### Claim 8 (depends on 1) The fixing tool of claim 1, wherein a part of the elongated plate portion connected with the head portion is bent to have a bending angle. ### Claim 9 (depends on 8) The fixing tool of claim 8, wherein the bending angle is 13 to 16 degrees. ### Claim 10 (depends on 1) The fixing tool of claim 1, wherein a width of the elongated plate portion has a predetermined curvature. ### Claim 11 (depends on 1) The fixing tool of claim 1, wherein the block includes an upper plate; and the protrusions protrude from a side surface of the upper plate. ### Claim 12 (depends on 11) The fixing tool of claim 11, wherein the other side surface of the upper plate is a curved surface having a predetermined curvature. ### Claim 13 (depends on 12) The fixing tool of claim 12, wherein the elongated plate portion is curved in a width direction to have a predetermined curvature, and the curvature of the elongated plate portion and the curvature of the upper plate are equal to each other. ### Claim 14 (depends on 1) The fixing tool of claim 1, wherein a ratio between a distance between opposing corners of the protrusions on the second side to a distance between opposing corners of the protrusions on the first side is 2:3. ### Claim 15 (depends on 1) The fixing tool of claim 1, wherein the head portion includes at least two guide holes formed such that guide pins are installed in at least two guide holes. ### Claim 16 (depends on 1) The fixing tool of claim 1, wherein the protrusions are symmetric about a midpoint of a space between the protrusions. ### Claim 17 (depends on 16) The fixing tool of claim 16, wherein the block comprises a hole for the fixing screw in the space between the protrusions. ### Claim 18 (depends on 1) The fixing tool of claim 1, wherein outer faces of the protrusions are adapted to support exposed surfaces of the tibia.
