Problems solved by technology
At present, in the reduction operation of the comminuted acetabular wall, it is very difficult to place multiple fracture fragments in their original positions, resulting in long operation time, uneven placement of fracture fragments, and many other problems, and even had to discard some of them. Fracture Fragment
So far, how to completely reduce multiple fracture fragments in the treatment of comminuted fractures of the acetabular wall has not been well resolved in clinical operations

Embodiment Construction
[0018] The present invention is made up of supporting plate 3 and clamping device 4.
[0019] The figure shows that the supporting plate 3 is a flat plate with a radian, and the radian of the supporting plate 3 matches the curvature of the rear wall of the acetabular wall 1, and the area of the supporting plate 3 is larger than the fractured area of the acetabular wall 1. The clamping device 4 is connected to the rear bottom edge of the supporting plate 3, and the clamping devices 4 are respectively located on both sides of the supporting plate 3, and the distance between the clamping devices 4 on both sides is greater than the transverse width of the fracture of the acetabular wall 1, and the clamping device 4 is clamped The device 4 is respectively clamped on the intact acetabular wall 1 on both sides of the fractured part. In order to better place the fracture fragment 2, the lower edge of the supporting plate 3 may have an upward raised edge, which blocks the fracture ...

An acetabular wall fracture auxiliary reduction shaping device belongs to the technical field of orthopedic medical instruments and is used for clinically realizing shaping reduction for acetabular wall fracture orthopedically. The technical scheme includes that the acetabular wall fracture auxiliary reduction shaping device consists of a supporting plate and clamping devices, the supporting plate is a flat plate with radian, the radian of the supporting plate matches with that of an acetabular wall, the area of the supporting plate is larger than the fracture area of the acetabular wall, andthe clamping devices are connected onto the rear bottom edge of the supporting plate, are respectively located on two sides of the supporting plate and respectively correspond to non-fractured acetabular walls on two sides of a fracture portion. During usage, the supporting plate is placed below the fracture position of the acetabular wall, the plate surface of the supporting plate is flushed with the rear wall surface of the acetabular wall, the supporting plate is fixed with the acetabular wall via the clamping devices, and a fracture block is placed on the upper surface of the supporting plate, so that perfect reduction of the fracture block is realized. The acetabular wall fracture auxiliary reduction shaping device is simple in structure and convenient in operation, resolves the difficult problem in terms of reduction of the comminuted fracture block of the acetabular wall by the aid of quite simple tools, and can be used for clinical treatment of fracture of various portions.
Description
technical field [0001] The invention relates to an orthopedic clinical appliance for plastic reduction of acetabular wall fractures, which belongs to the technical field of orthopedic medical devices. Background technique [0002] An acetabular fracture is an extremely serious injury. In recent years, acetabular fractures caused by high-energy injuries have been increasing, and surgical treatment has become the gold standard for the treatment of displaced acetabular fractures. With the development of internal fixation technology, the cure rate of acetabular fracture surgery has been significantly improved, but due to the complex anatomical characteristics and functional requirements of the fracture site, the incidence of postoperative complications of acetabular fracture remains high. Traumatic arthritis is one of the main postoperative complications. If it can be effectively controlled, it will greatly improve the quality of life of patients. Studies have shown that the r...
