Abstract
The invention discloses a distal end radius fracture plate, relating to a fixation device for treating bone fracture. The distal end radius fracture plate comprises a T-shaped plate, wherein the T-shaped plate can be partitioned into a transverse part and a longitudinal part; the transverse part and the longitudinal part are provided with 3-7 circular screw holes respectively; Claisen needle holes are formed at intervals on the edge of the transverse part; and an included angle of 140-175 degrees is formed by adjacent positions of the transverse part and the longitudinal part, so that the T-shaped plate has a longitudinal radian which is consistent with a distal end radius dissection bending angle. Due to shape structure design which is consistent with the distal end radius dissection characteristic, the fracture plate is appropriately placed on a distal end palm side of the reset radius, certain mechanical strength is kept, and bone fracture can be fixed tightly; and moreover, the distal end radius fracture plate is easy and reliable for using, and has high practicability.
Description
Technical field
The present invention relates to the fixture for the treatment of fracture, be specifically related to a kind of bone plate for radius far-end fracture.
Background technology
Radius far-end fracture is the modal fracture of upper limb, distal radius is shifted unconspicuous intraarticular and extra-articular fracture, and the unconspicuous stable type intercalation fracture of cripetura, by traditional manual reduction Gypsum Fibrosum or clamping plate extenal fixation, but to fracturing (AO-B type) in partial joint or fracture (AO-type) in perfect joint, the para-position that simple Gypsum Fibrosum extenal fixation is difficult to accomplish that articular surface is good and stable fixing, and then cause oar wrist and articulatio radioulnaris osteoarthritis.Radius far-end fracture, fracture is bordering on metaphysis, sometimes involves articular surface, and this type of fracture requires higher, especially more difficult for C 2,3 type fractures for reset and functional rehabilitation.Restoring board is taked to follow closely the operative therapy of internal fixtion sometimes, but cause locally osteoporosis because plate nail fixedly causes stress shielding, or screw loosening, exit equivalent risk, and the factor such as foreign body rejection, patient often needs to accept second operation, takes out metal inside-fixture.
Summary of the invention
It is simple and reliable that technical problem to be solved by this invention is to provide a kind of use, practical bone plate for radius far-end fracture.
Technical problem to be solved by this invention realizes by the following technical solutions,
A kind of bone plate for radius far-end fracture, comprise T-shaped plate, described T-shaped plate can be divided into lateral part and longitudinal component two parts, described lateral part and longitudinal component are respectively equipped with 3-7 circular screw hole, the edge of described lateral part is also interval with kirschner pin hole, the adjacent regions of described lateral part and longitudinal component forms 140-175 ° of angle, T-shaped plate is had to dissect with distal radius longitudinal radian that angle of bend is consistent.
Described lateral part and the adjacent regions of longitudinal component are provided with the curved slot in two ends.
The end, lateral part of described T-shaped plate is in bending arc-shaped structure.
Described kirschner pin hole is 2-5, rounded or ellipsoidal structure.
The diameter of described circular screw hole is 3-4mm.
The edge of described T-shaped plate is circular shape.
The invention has the beneficial effects as follows: the palm inclination angle due to distal aspect of the radius is 10-15 °, chi drift angle is 20-25 °, the present invention is by meeting the shape and structure design of distal radius anatomical features, make the distal radial palmar be placed on after the reduction of the fracture that blade plate is properer, it is made to keep certain mechanical strength, can fracture be fixedly secured, and use simple and reliable, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, a kind of bone plate for radius far-end fracture, comprise T-shaped plate, T-shaped plate can be divided into lateral part 5 and longitudinal component 2 two parts, 6 circular screw hole 1` are provided with at lateral part 5 place, longitudinal component 2 place is provided with 4 circular screw holes 1, and the diameter of circular screw hole 1,1` is 3.5mm, in order to fixing T-shaped plate; Edge in lateral part 5 is also interval with kirschner pin hole 4, and kirschner pin hole 4 is 4, rounded structure, and it is mainly used in temporary fixed or Post operation and assists fixation, also can pulverize the capable seam of bone block to periphery and be fixed; Lateral part 5 forms about 160 ° of angles with the adjacent regions of longitudinal component 2, T-shaped plate is had to dissect with distal radius longitudinal radian that angle of bend is consistent.
Lateral part 5 is provided with the curved slot 3 in two ends with the adjacent regions of longitudinal component 2, and it suitably can adjust the position of blade plate in fixation procedure, or is screwed in process at screw that to be that fracture end produces pressurization fixing.
The end, lateral part 5 of T-shaped plate is in bending arc-shaped structure, the nearly articular surface place with the metaphysis of distal radius is better fitted, and the edge of T-shaped plate is circular shape, longitudinal component 2 is located the backbone of distal radius, and what the design of T-shaped plate angle made that blade plate can be properer is placed on distal radial palmar.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
