Abstract

The invention relates to a bone plate, and in particular relates to a distal fibular anatomic bone plate. The distal fibular anatomic bone plate comprises a fibula body main plate and a fibular main plate, wherein 3 locking compression screw holes and 2 locking screw holes are formed in the fibula body main plate; the fibular main plate comprises a distal fibular plate and a front fibular plate; and through designing the shape of the bone plate to be matched with the human fibula, the distal fibular anatomic bone plate is better attached after being installed, and has smaller influence on skin tension. Moreover, locking screw holes are designed in the distal end of the bone plate, so locking screws are fastened in a multidirectional manner; through the design of the front fibular plate and the screw holes thereof, the screws are fixed from the front side to the rear side during the fixation, and are prevented from entering the articular surface of the fibula, so the fixation strength is improved; and the distal fibular anatomic bone plate can be conveniently applied in clinical surgery, and the pain of a patient is relieved.

Description

A kind of distal fibular flank dissection bone plate
Technical field
The present invention relates to a kind of blade plate, relate in particular to a kind of distal fibular flank dissection bone plate.
Background technology
Ankle fracture is common intra-articular fracture, and is that the topmost heavy burden of joint of the lower extremity one of is closed.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.Research shows in gait posture that 20% upwards strength is absorbed by external malleolus, therefore must do fibula strong interior fixingly, recovers desirable external malleolus length and normal valgus angle, recovers the anatomy relationship of distal fibular and tibia, maintenance Jower tibiofibular joint anatomical structure.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 simultaneously in its back lower place, have apart from the starting point of calf front and back ligament, calcaneofibular ligament at its end, distal fibular unstable fracture has not only been destroyed bone structure complete of external malleolus, affects the seriality of ligament terminal simultaneously.Therefore, the Anatomical Reconstruction of distal fibular fracture and the recovery of ankle stability have dependency.So the treatment of ankle fracture require anatomical reduction and strong fixing requirement higher, to prevent the generation of traumatic arthritis and degenerative arthritis, and the processing of outer fracture of ankle plays a crucial role to the stability of ankle joint.
At present, treatment distal fibular fractures method is various.Kirschner wire, tension band, screw etc. lack to be fixed the strong of fracture far-end, can not meet the fixing requirement that resets completely.And although fracture bone plate has certain constant intensity, but must be moulding, affect the intensity of steel plate, and thicker, skin closure tension force is large, easily occur the complication such as skin healing delay and infection, especially combine with bone piece far away or osteoporotic comminuted fracture for distal fibular comminuted fracture, lower tibiofibula, fracture of distal is still difficult to meet fixing requirement.Existing dissection type bone fracture plate or common locking bone fracture plate, multidirectional fixing for comminuted fractures of distal or bone density reduction person because not possessing screw, make that screw is easy to become flexible, hold weakens, and screw is easy to enter in articular cavity, cause clinical practice difficulty, affect therapeutic effect, cause suffering to patient.
Summary of the invention
The object of the invention is: the deficiency existing for prior art, provides a kind of anatomical features that meets distal fibular, effectively fixing distal fibular flank dissection bone plate.
For realizing the present invention's object, be achieved by the following technical solutions:
A kind of distal fibular flank dissection bone plate, comprises stem body mainboard and flank mainboard, and described stem body mainboard is provided with 3 locking compress screws and 2 locking screws, described flank mainboard comprises far-end wing plate and front side wing, far-end wing plate is provided with 3 locking screws and 4 grams of formula pin holes, described front side wing is provided with 2 locking screws and 2 grams of formula pin holes, angle α between the inclined plane of described front side wing end and the peak horizontal plane of far-end wing plate is 90 °, angle β between the axis of described stem body mainboard and far-end wing plate axis is 30 °, front side wing is designed to be provided with the narrow and thin reconstruction band that is arcuation, stem body mainboard and flank mainboard are with distal fibular the curved shape matching and mutually mate, laminating distal fibular outer surface, far-end wing plate is in the outside of distal fibular leading flank, the end of front side wing is fitted on the leading flank of fibula, screw orientation when the locking screw of least significant end is fixing on front side wing by the front side of distal fibular backward side enter, distal fibular front side and rear side are that two cortex is fixed, avoid screw to enter in distal fibular articular surface, on flank mainboard, screw is designed to insert the distribution that all screws do not clash into mutually after screw, the material of blade plate is steel or titanium-alloy thin-plate, the thickness of flank mainboard is 1.2mm, the thickness of stem body mainboard is 1.6mm.
?compared with prior art, the invention has the beneficial effects as follows: by the hone lamella shape design matching with human body fibula, more laminating after installation, less on skin tension impact.On blade plate far-end, be designed with locking screw simultaneously, make lock screw be multi-direction fixing, simultaneously by the design of front side wing and screw thereof, screw while making to fix is fixed toward rear side from front side, avoid entering articular facet for fibula, improve fixing intensity, in clinical operation, application conveniently, has reduced a lot of miseries to patient.
