It is the device in order to do wedge open higher order tibia bone cutting technique, the device where it includes the cut device in order to form the cut for bone cutting technique inside the tibia, as for the particular cut device, paralleling to the cut surface and the particular cut surface inside the tibia, the boundary line because the terminal it can point the cut which you can do includes the target device in order to specify, at the same time as for the aforementioned boundary line, inside the tibia inclination of the front - rear of the tibia vis-a-vis parallel is arranged parallel into the correct inside pages of the patient. To be method in order to do wedge open higher order tibia bone cutting technique, paralleling to the cut surface and the particular cut surface inside the tibia and the boundary line because the terminal it can point the cut which is formed and, it is the step which positions the positioning target device in order to specify, at the same time as for the aforementioned boundary line, to the inclination of the front - rear of the tibia being parallel in inside the tibia, are arranged parallel into the correct inside pages of the patient to the aforementioned step and the aforementioned cut surface which, paralleling the bone the cut and the aforementioned cut in the aforementioned boundary line the terminal in order to form wedge condition opening inside step and the bone which it can point,The step which makes the bone separate which is located on both sides of the aforementioned cut relatively and the step which makes the bone stabilize and, the method of including.楔開き高位脛骨骨切り術を行うための装置であり、脛骨内に骨切り術用切り込みを形成するための切り込み装置を含み、当該切り込み装置は、脛骨内に切り込み面と当該切り込み面に沿ってなされる切り込みを終端させるための境界線とを特定するための目標装置を含み、前記境界線は、脛骨内で脛骨の前-後傾斜に対して平行に且つ患者の正中面に平行に配置されている装置。楔開き高位脛骨骨切り術を行うための方法であり、脛骨内の切り込み面と、当該切り込み面に沿って形成される切り込みを終端させるための境界線と、を特定するための位置決め目標装置を位置決めするステップであり、前記境界線は、脛骨内において脛骨の前-後傾斜に平行で且つ患者の正中面に平行に配置される前記ステップと、前記切り込み面に沿って骨を切り込み、前記切り込みを前記境界線において終端させるステップと、骨内に楔状開口を形成
