When comminuted fracture occurs for acetabular bone, the extruding that rear pillar and Sifang District dislocates by late-segmental collapse, inwardly shiftings mostly
Position, from the perspective of mechanics stabilization, the barrier force of internal fixation steel plate is preferably from inside to outside.And steel plate used in the prior art is more
It fixes from top to down, positioned at arciform edge, the upper surface of ilium shame tuberosity and superior ramus of pubis, not only steel plate is difficult to moulding, is not easy docile
Bone face, and Laws of Mechanics is not met, rear pillar and Sifang District cannot be made to obtain good mechanical support.It is provided by the utility model
Arciform balsh plate, rear pillar ilium sit steel plate and Sifang District steel plate is placed in arciform edge and Sifang District inner surface, inside with fracture of acetabulum
What is shifted is contrary, can stop the interior shifting of acetabular posterior column and Sifang District from inside to outside just, be more from mechanics principle
Matched fixation, and Sifang District bone face is more smooth, steel plate is easy to moulding, docile bone face.Additionally by single preceding road, using rear pillar
Ilium sits Interal fixation rear pillar, can replace " two windows " screw substantially, avoids unnecessary risk, and fixation is more firm, and for
The low level rear pillar fracture for involving ischial spine, also can reach the fixation across fracture line, belongs to the absolute indication of this block steel plate.
It is different from the more smooth Sifang District in bone face and arciform edge medial surface, the dissection knot above acetabular anterior wall and arciform edge
Structure out-of-flatness, and be in multi-direction more planar distortions, therefore steel plate bending moulding is difficult, is difficult to be attached to bone face；Simultaneously as ilium
The outer arteriovenous of ilium and femoral nerve are close in shame tuberosity and superior ramus of pubis upper surface, need to dissect ligamentum inguinale, remove tough and tensile ilium
The structures such as shame bow, pectineal ligament, lacunar ligament, the nervus vasculairs that could dissociate appear arciform edge top and acetabular anterior wall bone face
To place steel plate, increase surgical procedure difficulty, and operation wound is larger.But in the fracture of acetabulum for merging antetheca fracture, no
It obtains and does not place one block of steel plate here, and antetheca steel plate and pubis steel plate provided in the utility model are strip steel plate,
Independent plasticity can be carried out for the shape for involving antetheca or fracture of pubis.
In addition, working as arciform the first screw hole of edge, the second screw hole of arciform edge, arciform edge third screw hole and bow provided by the present invention
When the 4th screw hole of shape edge is ellipse combination screw hole, user can be according to individual anatomical variation and a variety of different fracture classes
Type selects other steel plates to be combined with arciform balsh plate, and carries out sliding fine tuning by the oblong screw hole of steel plate, uses
When it is more convenient.
