The first bone plate 100 is provided with a bar-shaped hole 110 penetrating in the longitudinal direction at the center thereof. Preferably, grooves 120 for sliding connection with the second bone plate 200 are provided at left and right edges of the lower end surface of the first bone plate 100, respectively. Further preferably, limit stops 130 for preventing the second bone plate 200 from slipping are provided at both ends of the recess 120, respectively.
The second bone plate 200 is made of an alloy material. The second bone plate 200 is positioned on the upper end surface of the first bone plate 100 and is slidably coupled to the first bone plate 100. Preferably, bending parts 210 matched with the grooves 120 are respectively arranged at the left edge and the right edge of the second bone plate 200, so as to realize sliding connection of the second bone plate and the first bone plate. As a further preferred aspect, the thickness of the lower end surface of the bending part 210 is smaller than the depth of the groove 120, so as to reduce the contact area with the cortical bone. Because there is the periosteum that is used for keeping normal blood circulation on the surface of cortical bone, need peel off periosteum and cortical bone closely laminating when fixed in the clinical bone plate, consequently can lead to periosteum damage area great, influence blood circulation, in this embodiment, because the thickness of the lower terminal surface of kink is less than the degree of depth of recess, then terminal surface forms less area of contact with cortical bone under the first bone plate, furthest's protection periosteum protects human blood circulation, is favorable to accelerating patient and resumes.
