The present invention provides an interlocked bone plate system, which comprises an outer bone plate, an inner bone plate, and at least one screw. The outer bone plate is arranged outside a bone, and the inner bone plate is set in the medullary cavity to correspond to the outer bone plate. Each screw is set through the outer bone plate, the bone, and the inner bone plate to interlock the outer bone plate with the inner bone plate. Thus, the inner bone plate may provide further supporting effect to enhance the strength of the overall fixing structure and reduce the probability of failure of surgery.一種互鎖式骨板系統,包含有一外骨板、一內骨板以及至少一螺絲,外骨板設置於骨頭外,內骨板對應外骨板而設置於骨髄腔,各螺絲穿過外骨板、骨頭以及內骨板,使外骨板與內骨板相互鎖固,藉此內骨板可以提供進一步的支撐效果,使整體固定結構強度增加,而降低手術失敗的機率。10...互鎖式骨板系統12...外骨板121...第一穿孔122...第一內螺紋14...內骨板141...第二穿孔142...第二內螺紋16...螺絲161...頭部162...身部163...第一外螺紋164...第二外螺紋18...骨幹部20...骨骺部201...突伸片22...幹骺端部
