Description
Technical field
The present invention relates to medical instruments field, be meant outside blade plate behind a kind of tibial plateau that is used for posterior cruciate ligament stop place fracture especially.
Background technology
When the treatment fracture of the tibial plateau, all be to utilize blade plate the tibia main body to be fixed generally in the prior art in the front side of tibia.In recent years it is theoretical tibial plateau three posts to have occurred, and the clinicist begins to stress that os metastyloideum is folded into row directly to be resetted and support fixation.Also there is technology to notice at present to use the inboard or outside, the back dissection bone plate for locking in back to support and fixes.But when these technological means are all not to be noted treated complicated fracture of the tibial plateau; Processing to the posterior cruciate ligament stop bone piece that involved; The blade plate that special fixedly complicated fracture is involved back vent ligament stop does not appear in prior art as yet, has influenced the healing of this place's fracture.
Summary of the invention
The technical problem that the present invention will solve provides outside blade plate behind a kind of tibial plateau that is used for posterior cruciate ligament stop place fracture, is applicable to the treatment of complicated fracture of the tibial plateau.
For solving the problems of the technologies described above, embodiments of the invention provide technical scheme following:
On the one hand; Outside blade plate behind a kind of tibial plateau that is used for posterior cruciate ligament stop place fracture is provided; Comprise that the side of propping up plate portion with the suitable handle shape of proximal tibia rear side metaphysis part, with the suitable master of tibial plateau posterior lateral margin and covering posterior cruciate ligament stop place surface of bone props up plate portion; Thereby the front end of said handle shape part and said master prop up plate portion and are connected and constitute T-shaped or L shaped blade plate integral body; Said blade plate integral body have one be used to contact bone bottom side and one group of screw hole; Partly there is certain radian in the handle shape of said blade plate, can make said blade plate be attached on the tibial plateau rear pillar fully and make said master prop up plate portion to be attached at the tibial plateau posterior lateral margin, and said side is propped up the surface of bone that plate portion is covered in intersection stop place, back.
Wherein, the side of said blade plate is propped up plate portion and is become hook-type, and is covered in posterior cruciate ligament stop place surface of bone.
Wherein, the bottom side of said blade plate is the anatomical shape on tibial plateau rear pillar surface.
Wherein, the said blade plate master screw hole that props up plate portion points to the subchondral bone at tibial plateau rear respectively.
Wherein, said screw hole is the overlapping hole of screw hole, slip pressurization hole or slide pressurization hole and screw hole.
Wherein, become intersecting angle between the adjacent screw hole on the said blade plate handle shape part.
Wherein, the head end of the handle shape of a said blade plate part and main plate portion attenuation and be arc gradually.
Embodiments of the invention have following beneficial effect:
In the such scheme; Being used for behind the tibial plateau of posterior cruciate ligament stop place fracture the side of outside blade plate props up plate portion and becomes hook-shaped; Can be covered in posterior cruciate ligament stop place's surface of bone and it carried out effectively fixing, the handle shape partly has certain radian, when the complicated fracture of the tibial plateau of treatment; The handle shape part of the blade plate of present embodiment can attach good with metaphysis; Outer rim attaches well behind a main plate portion and the tibial plateau, and using this blade plate can fixedly secure the complicated fracture of the tibial plateau that involves the posterior cruciate ligament stop, is beneficial to the healing of patient's fracture.
Description of drawings
The structural representation of outside blade plate behind the tibial plateau that Fig. 1 is used for fracturing at posterior cruciate ligament stop place for embodiments of the invention;
Fig. 2 is used for outside blade plate behind the tibial plateau of posterior cruciate ligament stop place fracture for embodiments of the invention, place the sketch map at proximal tibia rear.
The specific embodiment
For technical problem, technical scheme and advantage that embodiments of the invention will be solved is clearer, will combine accompanying drawing and specific embodiment to be described in detail below.
Structural representation for outside blade plate behind the tibial plateau that is used for posterior cruciate ligament stop place fracture of the embodiment of the invention shown in Figure 1; As shown in Figure 1; Behind the tibial plateau that is used for posterior cruciate ligament stop place fracture of present embodiment outside blade plate comprise the handle shape part 1 suitable with tibial metaphysis, with tibia after the suitable master of outside joint margins prop up plate portion 2; And the side that covers posterior cruciate ligament stop place surface of bone is propped up plate portion 3; Thereby the front end of handle shape part 1 is connected with a main plate portion 2 and constitutes T-shaped or L shaped blade plate integral body; Blade plate integral body has a top side face, to be used to contact bottom side and one group of screw hole 4 of bone, and wherein blade plate handle shape part all has certain radian with a plate portion, makes blade plate can be attached at the tibial plateau rear pillar fully; And make a main plate portion be attached at the tibial plateau posterior lateral margin, side is propped up the surface of bone that plate portion is covered in intersection stop place, back.
Wherein, the bottom side of blade plate is the anatomical shape on tibial plateau rear pillar surface, can make the applying of blade plate and tibial plateau rear pillar tightr.Particularly, the bottom side of handle shape part 1 is the sagittal anatomical shape of proximal tibia rear side, can be attached to the sagittal plane of proximal tibia rear side fully; The bottom side of a main plate portion 2 is the anatomical shape of outside hat/frontal plane behind the proximal tibia, can be attached to the hat/frontal plane of proximal tibia rear side fully, and side is propped up 3 one-tenth hook-types of plate portion, is covered in the surface of bone at posterior cruciate ligament stop place.
Wherein, screw hole 4 can as shown in Figure 1ly be a screw hole, and further, screw hole 4 can also be the overlapping hole of slide pressurization hole or slide pressurization hole and screw hole.Particularly, the diameter of screw hole 4 can be 2.7mm～5mm.
