Labelling is following among the figure: acetabular bone wall 1, sclerite 2, supporting plate 3, clamping device 4, buckle 5, alligator clamp 6.
The specific embodiment
This utility model is made up of supporting plate 3 and clamping device 4.
Show among the figure that supporting plate 3 is for there being the flat board of radian, the radian of the radian of supporting plate 3 and acetabular bone wall 1 rear surface is complementary, and the area of supporting plate 3 is greater than the area of acetabular bone wall 1 fracture.Clamping device 4 is connected on the back base of supporting plate 3; Clamping device 4 lays respectively at the both sides of supporting plate 3; Distance between the both sides clamping device 4 is greater than the transverse width of acetabular bone wall 1 fracture, and clamping device 4 is clamped in respectively on the intact acetabular bone wall 1 with the fracture portions both sides.In order to reach the purpose of better putting sclerite 2, the lower limb of supporting plate 3 can have lug upwards, and lug blocks sclerite 2, can prevent that sclerite 2 to lower slider, is convenient to the doctor and operates better.
