Abstract
The invention relates to the technical field of medical instruments, in particular to a special shape locking bone fixing plate of acetabular posterior column or wall fracture. The bone fixing plate is provided with a thin metal plate body; the plate body is comprehensively shaped like a Y; one side edge of the plate body extends outwards to form an arc plate surface; the shape of the arc plate surface is matched with the shape of an acetabular rear upper edge; at least four asymmetric locking screw holes are formed in the arc plate surface; the upper end of the plate body is divided with two arms; the arm which is on the same side with the arc plate surface is long, and the other arm is short; a lower end arm is extended at the lower end of the plate body; and at least two locking screw holes are formed in each arm respectively. The bone fixing plate is stable and reliable, simple in operation, can be appropriately shaped, and is suitable for a special shape anatomic locking bone fixing plate for internal fixing of the acetabular posterior column or wall fracture.
Description
Technical field
The present invention relates to technical field of medical instruments, the special-shaped locking bone fracture plate of especially a kind of acetabular bone rear pillar or posterior wall fractures.
Background technology
The fracture at position was clinical common Orthopeadic Surgery disease around acetabular bone reached.Acetabular bone rear pillar, posterior wall fractures operation often need some implants to be fixed, with seriality and the stability of keeping fracture.Because of the acetabular bone anatomic form irregular, rear pillar, the posterior wall fractures form of expression are various, existing various internal fixation system is special because of the fracture site anatomic form, fixedly difficulty and poor stability, usually cause acetabular bone rear pillar, posterior wall fractures malreduction, articular surface out-of-flatness, fracture redisplacement, a mortar corresponding relation not normal etc., have in various degree permanent disability and problem such as operation once more.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of acetabular bone rear pillar or posterior wall fractures special-shaped locking bone fracture plate, to solve the technical problem of fixing difficulty of blade plate and poor stability.
The technical solution adopted for the present invention to solve the technical problems is: the special-shaped locking bone fracture plate of a kind of acetabular bone rear pillar or posterior wall fractures, has the metal sheet body, described plate body integral body is " Y " shape, one side of the plate body camber plate face that stretches out, the upper limb shape is complementary behind the shape of arc face and the acetabular bone, the arc face is provided with at least four asymmetric screw hole, two arms are told in the plate body upper end, wherein with arc face homonymy be long-armed, another is a galianconism, a lower end arm is extended in the plate body lower end, respectively is respectively equipped with at least two screw hole on above-mentioned three arms.
Better for the stability that further makes blade plate, the arc face is oval arch incisura, is respectively equipped with at least two and the acutangulate asymmetric screw hole of plate body and at least two and the vertical asymmetric screw hole of plate body on the plate face.
The invention has the beneficial effects as follows that the present invention is fixing reliable, simple to operate, can be suitably moulding, be applicable to that the internal fixation abnormity of acetabular bone rear pillar, posterior wall fractures is dissected locking bone fracture plate.

Among the figure: 1, plate body, 2, the arc face, 3, long-armed, 4, galianconism, 5, the lower end arm, 6 screw hole, 7, ala of ilium, 8, ischium.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The special-shaped locking bone fracture plate of a kind of acetabular bone rear pillar shown in Fig. 1-4 or posterior wall fractures, has the metal sheet body, described plate body integral body is " Y " shape, one side of the plate body camber plate face that stretches out, the upper limb shape is complementary behind the shape of arc face and the acetabular bone, the arc face is provided with at least four screw hole, two arms are told in the plate body upper end, wherein with arc face homonymy be long-armed, long-armedly be fixed on the ala of ilium by screw, another is a galianconism, galianconism is fixed on the incisura ischiadica outer rim ala of ilium by screw, a lower end arm is extended in the plate body lower end, and the lower end arm is fixed near section of ramus of ischium by screw, respectively is respectively equipped with at least two screw hole on above-mentioned three arms.
Better for the stability that makes blade plate, the arc face is oval arch incisura, is respectively equipped with at least two and the acutangulate asymmetric screw hole of plate body and at least two and the vertical asymmetric screw hole of plate body on the plate face.The acetabular bone trailing edge is a part that constitutes hip joint, is globoidal structure, is covered in femoral head, and is very big to integrity and the stable meaning of keeping hip joint.Because of an acetabular bone trailing edge bone ancient piece of jade, round, flat and with a hole in its centre is thinner, nail hole and plate body acutangulate, and hold-down screw is controlled ability by force and be difficult for entering articular cavity and influence hip joint function.Acutangulate and the fixing fracture of vertical asymmetric lock screw formation crossings on different level with plate body, make fixing stronger stablizing, be beneficial to the early stage functional exercise of hip joint.
