[0002] The ilium is a component of the hip bone, forming the posterosuperior part of the hip bone. It is divided into the ischial body and the iliac wing. The iliac wing is wide in the front and narrow in the back. The projections below them are called the anterior inferior iliac spine and the posterior inferior iliac spine, respectively. Below the posterior inferior iliac spine is the deep greater sciatic notch. The inner surface of the iliac wing is smooth and slightly concave, called the iliac fossa. The lower boundary of the fossa is the prominent arcuate line, and the auricular surface is located above and behind it, forming the sacroiliac joint with the sacrum.
[0003] Car accidents, falls from heights, and other injuries often result in displacement and comminuted fracture fragments, which are difficult to treat with simple reduction and fixation. Posterior column fractures of the acetabulum often involve the posterior column, a complex area that is frequently combined with other serious injuries, such as hip dislocation and femoral head fractures, increasing the difficulty of treatment. For trauma involving central hip dislocation combined with acetabular fracture, existing technologies lack effective treatment aids. Therefore, this utility model proposes an integrated internal iliac ischium plate for reduction and fixation to solve the problems existing in the prior art. Utility Model Content

[0006] The beveled plate, connecting plate, and arc-shaped plate are all provided with fixing holes, and there are multiple sets of fixing holes.
[0007] A further improvement is that the bottom of the beveled plate is arc-shaped, and one side of the bottom of the beveled plate is provided with an inner bevel. The arc surface of the bottom of the beveled plate is adapted to the curvature of the iliac crest, and the inner bevel is adapted to the tilt angle of one side of the iliac crest.
[0008] A further improvement is that one end of the iliac wing is connected to the ischium body, and the ischium body is provided with an arcuate line. The bottom of the arcuate plate is provided with an inner arc chamfer, and the inner arc chamfer is adapted to the arcuate line.
[0009] A further improvement is that: one side between the iliac wing and the ischium is the greater sciatic notch, the inner extension protrusion extends to the greater sciatic notch, and the inner groove is inserted into the inner side of the greater sciatic notch.
[0010] A further improvement is that the connecting plate and one side of the inner extension protrusion form an angle opening, and the angle opening is adapted to the transition angle between the iliac wing and the greater sciatic notch.
[0011] A further improvement is that the beveled plate, the connecting plate, and the arc-shaped plate are integrally formed.
