Detailed Description
The utility model is described in further detail below with reference to the attached drawings and embodiments:
as shown in figures 1-2, the novel tibial plateau inner rear side anatomical locking bone plate is 7-shaped, the bone plate is rounded, the tissue around an affected part can be prevented from being damaged, the radius of the rounded edge is 0.3mm, and the radius of the rounded edge is 2mm. The bone fracture plate comprises a proximal transverse arm 1 and a distal longitudinal arm 2, wherein the proximal transverse arm 1 comprises an inner platform section 6 and a rear inner platform section 7, the distal longitudinal arm 2 comprises a metaphyseal section 3 and a shank diaphysis section 4, and pre-bending grooves 5 are respectively formed in two sides of a joint of the proximal transverse arm 1 and the distal longitudinal arm 2. The proximal cross arm 1 supports the inner side and the rear inner side of the tibia platform 14, and the width of the proximal cross arm 1 is 8mm and the length is 35mm; the distal trailing arm 2 is fixed on the posterior side of the upper tibial segment, the distal trailing arm 2 has a width of 10mm, the metaphyseal segment 3 has a length of 15mm, and the tibial diaphysis segment 4 has a length of 55mm. Three first locking screw holes 8 with the diameter of 3.5mm are arranged on the inner platform section 6, the hole spacing is 3mm, and two Kirschner pinholes 15 with the diameter of 1.5mm are additionally arranged on the inner platform section 6. Two second locking screw holes 9 with the diameter of 2.7mm are arranged on the rear inner platform section 7, and the hole spacing is 5mm.
