Abstract
The utility model relates to a bone plate and in particular to a fibular distal flank anatomic bone plate. The fibular distal flank anatomic bone plate comprises a stem body main plate and a flank main plate, wherein 2-4 locking compression screw holes and 0-4 locking screw holes are arranged in the stem body main plate; the flank main plate comprises a distal flange plate and a front side flange plate; and through designing the shape of the bone plate to be matched with a human fibula, the fibular distal flank anatomic bone plate is better attached after being installed, and has smaller influence on skin tension. Meanwhile, locking screw holes are designed in the distal end of the bone plate, so locking screws are fastened in a multidirectional mode; meanwhile, through a design of the front side flange plate and the screw holes thereof, the screws are fixed from the front side to the rear side during fixation, and are prevented from entering into the articular surface of the fibula, so the fixation strength is improved; and the fibular distal flank anatomic bone plate can be conveniently applied in clinical surgery, and pain of a patient is relieved.
Description
Technical field
This utility model relates to a kind of blade plate, relates 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 the ankle joint reduction, and secondly the person is the reparation to internal malleolus and lower tibiofibula ligament.Studies show that in the gait posture that 20% upwards strength is absorbed by external malleolus, so must do fibula strong interior fixingly, recovers desirable external malleolus length and normal valgus angle, recover the anatomy relationship of distal fibular and tibia, maintenance Jower tibiofibular joint anatomical structure.Distal fibular not only consists of Jower tibiofibular joint with distal tibial, consist of apart from diseased joint with astragalus simultaneously, and brevis and brevis tendon ditch is arranged in its back lower place simultaneously, have apart from the starting point of calf front and back ligament, calcaneofibular ligament at its end, the distal fibular unstable fracture has not only been destroyed bone structure complete of external malleolus, affects simultaneously the seriality of ligament terminal.Therefore, the Anatomical Reconstruction of distal fibular fracture and the recovery of ankle stability have dependency.So the treatment of ankle fracture requires anatomical reduction and strong fixing requirement higher, preventing 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 satisfy the fixing requirement that resets fully.Although and fracture bone plate has certain constant intensity, but must be moulding, affected the intensity of steel plate, and thicker, skin closure tension force is large, the complication such as skin healing delay and infection occur easily, especially unite with bone piece far away or osteoporotic comminuted fracture for distal fibular comminuted fracture, lower tibiofibula, fracture of distal still is difficult to satisfy 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 the articular cavity, cause the clinical practice difficulty, affect therapeutic effect, cause suffering to the patient.
Summary of the invention
The purpose of this utility model is: the deficiency for prior art exists provides a kind of anatomical features that meets distal fibular, effectively fixing distal fibular flank dissection bone plate.
For realizing the purpose of this utility model, 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 2～4 locking compress screws and 0～4 locking screw; Described flank mainboard comprises far-end wing plate and front side wing, the far-end wing plate is provided with 3～5 locking screws and 2～4 gram formula pin holes, described front side wing is provided with 2 locking screws and 2 gram formula pin holes, angle α between the peak plane of the inclined plane of described front side wing end and far-end wing plate is 80 °～100 °, and the angle β between the axis of the axis of described stem body mainboard and far-end wing plate is 0 °～30 °.
As preferably, described front side wing is provided with the reconstruction band that is arcuation.
As preferably, the material of described blade plate is steel or titanium-alloy thin-plate, and thickness is 1mm～4mm.
Compared with prior art, the beneficial effects of the utility model are: by the hone lamella shape design that matches with the human body fibula, more fit after the installation, and less on the skin tension impact.Simultaneously be designed with the locking screw at the blade plate far-end, so that lock screw is multi-direction fixing, the simultaneously design by front side wing and screw thereof, so that the screw fixedly the time is fixed toward rear side by the front side, avoid entering articular facet for fibula, improve fixing intensity, it is convenient to use in the clinical operation, has reduced a lot of miseries to the patient.
