Combined acetabular bone fracture fixation plate

Abstract

The invention discloses a combined acetabular bone fracture fixation plate, and relates to the technical field of internal bone fracture fixation plates. The combined acetabular bone fracture fixationplate comprises a reconstruction boone fracture fixation plate, a supporting bone fracture fixation plate main plate, a supporting bone fracture fixation plate auxiliary plate and a reinforcement plate; the reconstruction bone fracture fixation plate is in a straight shape or an arc shape for adapting to the shape of the inner wall of the pelvis, is provided with a plurality of reconstruction bone fracture fixation plate screw holes at intervals and can be fixed to the anterior and posterior columns of the acetabular bone through first screws; the supporting bone fracture fixation plate mainplate comprises a main plate body part and main plate end parts, the main plate end parts are connected to the left and right ends of the main plate body part, the main plate body part is provided with a plurality of main plate screw holes at intervals, and each main plate end part is provided with an oval screw hole and can be fixedly connected with the reconstruction bone fracture fixation platethrough a second screw. According to the combined acetabular bone fracture fixation plate, the supporting bone fracture fixation plate main plate and the supporting bone fracture fixation plate auxiliary plate can be spread by supporting screws, so that the fracture is reset and fixed, the effect is good, and the screws are prevented from piercing the bone while the requirement for providing thefixation effect on some parts is met.

Description

technical field [0001] The invention relates to the technical field of fracture internal fixation bone plate, in particular to a combined acetabular bone plate. Background technique [0002] Acetabular fracture is a serious trauma, and many wounded lose their lives. Even if they are out of danger after rescue, patients often suffer long-term pain caused by traumatic arthritis of the hip joint and necrosis of the femoral head in the later stage. [0003] With the development of medical technology, the effect of surgical treatment on patients with significantly displaced acetabular fractures has been greatly improved, but fractures involving the medial wall of the acetabulum are difficult to expose and reduce due to their deep location and complex surrounding anatomy. , because the bone is thin and close to the femoral head, it cannot be fixed and becomes a difficult point in treatment. [0004] Since Hirvensalo applied the Stoppa approach to the treatment of acetabular fract...
