Embodiment Construction

[0009] specific implementation plan

[0010] When undergoing open reduction surgery for anterior acetabular column fractures, the arcuate line to the pubic tubercle is exposed during the operation, the fracture end is reset, and the arc segment twisted in multiple directions corresponds to the arcuate line and the pubic comb. The rear bending section corresponds to the inner surface of the pubic tubercle; there is a deep and smooth concave between the fixation holes of the reconstruction bone plate, which can accurately bend, bend, twist and change the shape of the bone plate, making the bone plate and the bone surface Fitting; the two-way self-pressurization of the two-way self-pressurized fixation of the oval-shaped screw holes, which are shallow at both ends and deep in the middle, adjusts the distance between the fracture ends, and the micro-deformation of the bone plate is produced by screw pressure, so that the bone plate and the bone surface fit more closely. The arc se...

Abstract

The invention relates to a special-shaped bone fracture plate from a pelvis arcuate line to a tuberculum pubicum. The special-shaped bone fracture plate comprises a torsional arc-shaped section and a bended section on the rear side at the rear end, wherein the arc-shaped section of the bone fracture plate corresponds to the pelvis arcuate line and a pecten pubis, the torsional section on the rear side at the rear end of the bone fracture plate corresponds to the inner face of the tuberculum pubicum, and the arc-shaped section of the bone fracture plate is integrally connected with the bended section on the rear side at the rear end to form the reconstructed bone fracture plate which changes three-dimensionally. Two sections of planes of the bone fracture plate are intersected at angles to form a beam-shaped structure. The bone fracture plate has the advantages that the bone fracture plate is good in adaptability, the surgical difficulty and degree of operative wounds are reduced, a fixed bolt is prevented from being implanted into an articular cavity and the like.

Description

technical field [0001] The invention relates to a bone plate for fracture operation treatment, in particular to a special-shaped bone plate from the arcuate line of the pelvis to the pubic tubercle. Background technique [0002] Anterior acetabular column fracture is a joint-involving and unstable fracture, which requires open anatomical reduction and effective internal fixation to facilitate early active movement of the joint and achieve good functional recovery. The bone plate used for internal fixation in surgery requires a good structure and a certain strength to meet the requirements of internal fixation. At present, the internal fixation of anterior acetabular column fractures usually adopts a single-plane arc-shaped reconstruction plate for fixation. Due to the large changes in the three-dimensional curvature and plane of the anatomical arcuate line of the acetabular anterior column to the pubic tuberosity and surgical Insufficient exposure, the shaping of the single...
