Description
Technical field
This utility model relates to a kind of blade plate, is mainly used in distal fibular fracture (fracture at external malleolus position, Danis-Weber typing: A/B/C type), tibiofibular syndesmotic injuries etc.
Background technology
As the ankle of one of the weight-bearing joints that lower limb are main, its occur damage be clinical in the most common, account for the first place of intra-articular fracture, and single fracture of ankle beyond fracture of ankle i.e. distal fibular fracture the most common, account for 57.6% of sprained ankle.And along with the generation of high-energy damage, most complicated sprained ankles is all with outer fracture of ankle.Therefore, treatment extremely clinical orthopaedics doctor and the social extensive concern gradually of distal fibular fracture.Distal fibular not only forms Jower tibiofibular joint with distal tibial, form apart from diseased joint with astragalus simultaneously, there is and brevis and brevis tendon ditch in its back lower place simultaneously, the starting point of ligament, calcaneofibular ligament before and after calf is had at its end, distal fibular unstable fracture not only destroys the complete of the bone structure of external malleolus, affects the seriality of ligament terminal simultaneously.Research shows that the upwards strength of in gait posture 20% is absorbed by external malleolus, and the length of external malleolus and para-position are most important links in ankle joint reduction, and secondly person is the reparation to internal malleolus and lower tibiofibula ligament.Therefore, the Anatomical Reconstruction of distal fibular fracture and the recovery of ankle stability have dependency.The treatment of ankle fracture will the portion's of solving reset recover the anatomical structure such as the normal valgus angle of external malleolus and length, to adapt to front lower wide, the rear narrow form of astragalus, and require to reach effective, strong fixing, for early ambulant provides stability, to prevent the generation of traumatic arthritis and degenerative arthritis, and the stability of the process of outer fracture of ankle to ankle joint plays a crucial role.
At present, fixture and the mode for the treatment of outer fracture of ankle are more.Tradition Kirschner wire, tension band and simple screw etc. are fixing all for want of can not meet clinical requirement completely to the strong fixing of fracture far-end.Although common 1/3 cast occurred in recent years, reconstruction plate have certain intensity, but and do not meet external malleolus anatomical features and must be moulding, especially fracture or osteoporotic, comminuted fracture with Weber A far away, Type B for Inferior tibiofibular joint, because not specialized designs is used for external malleolus, make the screw fixed qty of fracture distal part limited and be difficult to meet strong effectively fixing requirement.And though trifolium-shaped fracture bone plate increases to some extent at the screw number that far-end is fixing in recent years, but because distal contact surface is excessive, need soft tissue thoroughly to peel off and damage comparatively large, and the anti-bonding streng of plain screw is more weak, is still difficult to the mechanical requirements meeting syntripsis or osteoporotic fracture.Existingly be specifically designed to the dissection type bone fracture plate of distal fibular or common locking bone fracture plate, though reach anatomical requirements, but the design of its screwed hole is to be fixed in the same way, and the actual screw number that can fix of far-end of fracturing is also very limited, and screw is implanted by intraarticular inside lateral, often take care screw in clinical and enter intraarticular, make, in operation, screw length is all less than actual measured value, make clinical practice and operation are made troubles, and affect fixing active strength and cause being easy to loosening, often therefore need braking and cause patient can not functional exercise too early, especially for Weber A, Type B fracture or osteoporotic, fixing of comminuted fracture is always comparatively thorny.To this, no matter be that orthopedist or patient urgently wish can to create for outer fracture of ankle that a fixing hold is stronger, clinical manipulation is easier, soft tissue tension affects little special external malleolus dissection bone plate, to improve therapeutic effect and to improve the misery that patient must not brake then for a long time.
Utility model content
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provide one to have Double-wing-plate, effective hold-down screw number is many, the external malleolus blade plate that constant intensity is high.
For realizing the object of this utility model, being achieved by the following technical solutions: a kind of external malleolus blade plate, including the mainboard of strip and one-body molded at first wing plate of mainboard near side, end and the second wing plate; Described mainboard is made up of the first plate body connected successively, the second plate body and the 3rd plate body, and the side of described first plate body is straight flange, the curved limit, side of the second plate body and the 3rd plate body; Be all that arc transition is connected between described second plate body and the side of the first plate body, the 3rd plate body, and the second plate body, relative first plate body side, the 3rd plate body side bend in the opposite direction; The first described wing plate and the second wing plate are connected in the arcuate flanks of the 3rd plate body indent, and the first wing plate is near the second plate body, and the second wing plate is in the end of the 3rd plate body away from the second plate body; The first described plate body offers 2-6 locking compress hole, the first plate body has the first pin hole away from the end opens of the second plate body; Position near the first plate body on the second described plate body offers a locking compress sliding eye, and the position near the 3rd plate body on the second plate body offers first lock hole; Position near the first wing plate on described 3rd plate body offers the second lock hole, position near the second wing plate on 3rd plate body offers the 3rd lock hole, position near the second lock hole and away from the 3rd lock hole on 3rd plate body offers second pin hole, and the 3rd plate body offers two the 3rd pin holes between the second lock hole and the 3rd lock hole; The first described wing plate end forms a circular universal orifice plate, and the centre of universal orifice plate offers a universal lock hole, and the angle a formed between universal orifice surface and the 3rd plate body inner surface is 80-90 degree; The second described wing plate end forms a circular locking orifice plate, and the centre of locking orifice plate offers the 5th lock hole, and the angle b formed between described locking orifice surface and the 3rd plate body surface is 100-110 degree; The axis of the first described pin hole, the first lock hole, the second lock hole, the 3rd lock hole and the 5th lock hole is not parallel to each other; The first described wing plate, the second wing plate are all curved in the longitudinal direction.
Compared with prior art, the beneficial effects of the utility model are: described mainboard is integrally made up of three sections of plate bodys, and the second plate body, relative first plate body side, the 3rd plate body side bend in the opposite direction, the connection of such mainboard and fibula meets anatomical features and less to the tension force of skin soft tissue more, the screw thread of the lock hole design on it makes lock screw reduce and enters IA risk, very firm after being connected by lock screw, all directions are all not easy produce displacement; 3rd plate body position is formed multidirectional fixing by arranging two between wing plate and lateral malleous portion, bonding strength is high, is especially suitable for the fixing of the distal fibular fracture of below Inferior tibiofibular joint.The second described lock hole, the 3rd lock hole and the 4th lock hole are near the position of two wing plates, after being fixed by the lock screw of different angles, in addition two wing plates are coordinated, screw orientation not only on it is avoided entering intraarticular, and it is multidirectional stable fixing more to ensure that the external fracture of ankle of blade plate fixedly plays 3 D stereo, be conducive to patient's rehabilitation quickly as before, ensure therapeutic effect.
