Description
Technical Field
The utility model relates to a medical fixed plate of orthopedics especially relates to a tibial plateau back outer side fixed plate.
Background
Tibial plateau fractures are common fractures in orthopedics clinic, the incidence rate of combined posterior lateral plateau fractures is high, and the incidence rate of the combined posterior lateral plateau fractures accounts for 44% of tibial plateau fractures in literature reports. The presence of fibula, lateral collateral ligament, common peroneal nerve, and external inferior knee artery around the posterolateral tibial plateau leads to difficulties in exposure, reduction, and fixation. Through single anterolateral approach, lack the fixed steel sheet of the outside platform after being used for specially at present, current steel sheet is difficult to realize putting the nail through anterolateral approach to the outside platform after and fixes, and uses the fix with screw to the cracked outside platform fracture after of rear cortex purely, is difficult to realize supporting role.
Therefore, the utility model provides a tibial plateau posterolateral fixed plate, which can realize effective supporting and fixing of a posterolateral platform through single anterolateral approach, the first part of the fixed plate can realize the support of a posterolateral platform joint surface through screws, and simultaneously, a steel plate is fixed around the posterolateral platform; the second part of fixed plate can realize the support to the bone piece of back outside platform, prevents that the bone piece from shifting to the rear, and the fixed strength of fixed plate and rear platform can be increased to the friction reinforcing portion of surface design, and it need not to put the design of nail and has solved the difficult problem of nail difficulty to the back outside platform of the way of going into simultaneously in the anterolateral.
SUMMERY OF THE UTILITY MODEL
In order to realize the purpose of the utility model, the following technical scheme is adopted to realize:
a tibial plateau posterolateral fixation plate, wherein: the tibial plateau back outer side fixing plate comprises a strip-shaped fixing plate main body, the strip-shaped fixing plate main body comprises a first portion and a second portion, one side edge of the first portion is flush with one side of the second portion, the other side edge of the second portion extends outwards from the other side edge of the first portion and bends downwards to form a bending portion, a through hole is formed in the first portion, and a friction enhancing portion is arranged on the second portion.
The tibial plateau posterolateral fixation plate, wherein: a row of through holes are formed in the first portion along the length direction, and the number of the row of through holes is at least two.
The tibial plateau posterolateral fixation plate, wherein: the friction enhancing portion is provided on a lower surface of the second portion.

Detailed Description
The following describes in detail embodiments of the present invention with reference to fig. 1-2.
As shown in fig. 1 and 2, the tibial plateau posterior-lateral fixation plate of the present invention includes a bar-shaped fixation plate main body, the bar-shaped fixation plate main body includes a first portion 1 and a second portion 2, one side edge of the first portion 1 is flush with one side of the second portion 2, and the other side edge of the second portion 2 extends outward from the other side edge of the first portion 1, so that the width of the second portion 2 is greater than the width of the first portion 1. The widening of the second portion 2 increases the support area for the rear platform and increases the support strength.
The first portion 1 is bent downward such that the fixing plate body has an arc shape and the upper and lower surfaces of the first portion 1 are smoothly connected with the upper and lower surfaces of the second portion 2.
The outwardly extending edge of the second portion is bent downwardly to form a bend 22, the bend 22 being at an angle of between 15 and 30 degrees.
A row of through holes have been seted up on the length direction along first portion 1, a row of through holes includes the round hole 11 at both ends, and the sliding hole 12 in the middle of two round holes 11, sliding hole 12 shape is rectangular shape. The through hole is used for passing through a fixing screw to fix the tibial plateau.
Two rows of teeth 21 protruding outwards are arranged on the lower surface of the second part 2, an included angle a of the top side wall of each tooth 21 is an acute angle, and the angle range of the included angle a is as follows: 20 DEG-a-45 DEG, said angle a preferably being 30 DEG, wherein a row of teeth 21 is arranged on the bend 22 of the second part.
The material of the tibial plateau posterolateral fixing plate is stainless steel, titanium alloy and the like.
The utility model discloses an outside fixed plate behind tibial plateau is fixed through single anterolateral approach when using, is satisfying the back that resets to the outside platform of back, places the fixed plate along the platform edge, makes fixed plate first portion and outside platform edge laminating, and the fixed plate second part is laminated with the rear platform. Firstly, the sliding hole cortical bone screw is placed in the direction from the back to the front, and the fixing plate is pressurized, so that the teeth of the second part of the fixing plate are attached to the rear platform. Then, two locking screws are arranged in front and at the back, so that the support of the collapsed joint surface of the back outer side platform is realized while the steel plate is fixed.
Through the utility model discloses, can realize that the single anterolateral approach is to the effective fixed of posterolateral side platform, solve the anterolateral approach and implanted the difficult problem of difficulty to the fixed time screw of posterolateral side platform, the structural design of fixed plate second part has realized the effective support to the rear platform simultaneously, can prevent the aversion to the rear of posterolateral side platform bone piece.
